reported in PR 49080. I did look in the package configury to figure
out which ones were mutually connected, but I may have gotten it
wrong as there's a monumental maze of m4 autotoolery.

Unflushed (broken) stdout seen on Darwin was fixes.
|
|
---------------------
- Now compiles on GNU/kFreeBSD
- Pool: `AF_PIPE` address fixed so that it works on recent Windows versions
in combination with Python 2.7.7.
- Pool: Fix for `Supervisor object has no attribute _children` error.
- Pool: Fixed bug with human_status(None).
- Pool: shrink did not work properly if asked to remove more than 1 process.

mk-configure>=0.27.0 is required for build.
Option -X was introduced to paexec(1) for ignoring
calculator's stdout.
PAEXEC_ENV environment variable sets a list of variables passed to
the calculator.
PAEXEC_TRANSPORT environment variable sets the transport unless
option -t was applied.
PAEXEC_NODES environment variable sets the nodes unless
option -n was applied.
pareorder(1) is a synonym for paexec_reorder(1)

Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Fix PR pkg/48777
|
|
|

This seems to have been fixed in a previous version. At least "import
billiard" works from the interpreter. From CHANGES.txt:
- Fixes SemLock on Python 3.4 (Issue #107) when using
``forking_enable(False)``.
- Pool: Include more useful exitcode information when processes exit.

|
|

These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or
ignored otherwise.

Fixes issues where a newer GCC has been chosen by the user but the GCC_REQD
was forcing an older (and broken) one to be pulled regardless.

using it.

1) The shared library isn't installed with py33. The package uses a pure
python implementation;
2) The connection and reduction functions are installed in different
directory names depending on python major version. From CHANGES.txt:
3.3.0.16 - 2014-02-11
---------------------
- Previous release was missing the billiard.py3 package from MANIFEST
so the installation would not work on Python 3.
3.3.0.15 - 2014-02-10
---------------------
- Pool: Fixed "cannot join process not started" error.
- Now uses billiard.py2 and billiard.py3 specific packages that are installed
depending on the python version used.
This way the installation will not import version specific modules (and
possibly crash).
3.3.0.14 - 2014-01-17
---------------------
- Fixed problem with our backwards compatible ``bytes`` wrapper
(Issue #103).
- No longer expects frozen applications to have a valid ``__file__``
attribute.

sge_conf(5) are now 100 without CSP. See
<http://arc.liv.ac.uk/SGE/howto/sge-security.html>
* RPM layout changed to put relevant ones under noarch (on RHEL6 and
recent Fedora), with a separate guiinst package
* Memory values can be input and output in TB or tB (possible
incompatibility parsing output)
* Reduce execd CPU time reading large smaps files from Linux /proc and
provide USE_SMAPS in execd_params to turn it on (default now off
because huge smaps are generated by some programs)

* Make SGE template an RPM conf file
* Incompatible changes

* Enhancements
* SGE_BINDING is set in the environment for all types of binding
* New jobstats(1) provides historical job summary
* Berkeleydb spools can optionally be opened "private" to allow
operation on NFS3 filesystems. Currently no installer support, but

* Improve install template defaults
* GPU load sensor (dist/util/resources/loadsensors/gpu-loadsensor.c)
* Allow building Kerberos/GSSAPI security modules against Heimdal
(but GSS is still not properly usable)
* Support arm and mipsel on GNU/Linux, completing the set
of official Debian Linux-based ports
* Support for OpenBSD (untested)
* Preliminary support for Cygwin: everything builds, clients work
(lightly tested), daemons need fixing
* Add ja_task_id to expandable variables in ckpt_command and similar
methods
* distinst supports installation with install(1) for use with -local
* Incompatible changes
* The CA directory is now /var/lib/sgeCA instead of /var/sgeCA
but installation will offer to move it [fixme]
* Drop (any pretence at) support for Cray/Unicos, NEC SX, Darwin 6
* The spool format for parallel job tasks has changed from any previous
version built with qsort_args (as above), which will make live
upgrades from such a version fail on nodes running parallel jobs
* Other changes
* Extensive internal changes to improve robustness, e.g. of
string-handling against buffer overruns -- somewhat error-prone
and may have caused regressions; more required
* Install script allows rsh et al to be omitted from binary distribution
in favour of ssh
Version 8.1.0
-------------
* Security fix
* Prevent users other than root deleting entries with sgepasswd
* Version numbering
* Switch to a more logical numbering scheme now that the Univa
baseline is irrelevant
* Bug fixes
* Other changes
* Hadoop support now for a more recent Hadoop distribution (see
README.BUILD)
Version 8.0.0e
--------------
Mostly build and security issues
* Bug fixes
* Security fixes
The first fix is for a trivial remote root by a valid user. The
others, including fixes for potential buffer overruns in daemon and
setuid programs, may or may not be exploitable.
* Sanitize the environment before executing remote startup programs etc.
Somewhat incompatible: LD_LIBRARY_PATH etc. may need to be set
differently. See the security notes in remote_startup(5) and
sge_conf(5). (CVE-2012-0208, thanks to William Hay)
* Don't write initial log messages in /tmp. Somewhat
incompatible: initial messages now in syslog.
* Avoid using mktemp. (Probably not a significant problem.)
* Control core dumps under setuid etc. with SGE_ENABLE_COREDUMP.
(Not normally a security issue.)
* Bounds checking in replace_params
* Avoid execd crash and possible overruns
* Fixes for buffer overrun and other improvements for (setuid
program) sgepasswd

Based on work of Jason Bacon published in WIP.
* Changes in Slurm 2.6.4
========================
-- Fixed sh5util to print its usage.
-- Corrected commit f9a3c7e4e8ec.
-- Honor ntasks-per-node option with exclusive node allocations.
-- sched/backfill - Prevent invalid memory reference if bf_continue option is
configured and slurm is reconfigured during one of the sleep cycles or if
there are any changes to the partition configuration or if the normal
scheduler runs and starts a job that the backfill scheduler is actively
working on.
-- Update man pages information about acct-freq and JobAcctGatherFrequency
to reflect only the latest supported format.
-- Minor document update to include note about PrivateData=Usage for the
slurm.conf when using the DBD.
-- Expand information reported with DebugFlags=backfill.
-- Initiate jobs pending to run in a reservation as soon as the reservation
becomes active.
-- Purged expired reservation even if it has pending jobs.
-- Corrections to calculation of a pending job's expected start time.
-- Remove some vestigial logic treating job priority of 1 as a special case.
-- Memory freeing up to avoid minor memory leaks at close of daemons
-- Updated documentation to give correct units being displayed.
-- Report AccountingStorageBackupHost with "scontrol show config".
-- init scripts ignore quotes around Pid file name specifications.
-- Fixed typo about command case in quickstart.html.
-- task/cgroup - handle new cpuset files, similar to commit c4223940.
-- Replace the tempname() function call with mkstemp().
-- Fix for --cpu_bind=map_cpu/mask_cpu/map_ldom/mask_ldom plus
--mem_bind=map_mem/mask_mem options, broken in 2.6.2.
-- Restore default behavior of allocating cores to jobs on a cyclic basis
across the sockets unless SelectTypeParameters=CR_CORE_DEFAULT_DIST_BLOCK
or user specifies other distribution options.
-- Enforce JobRequeue configuration parameter on node failure. Previously
always requeued the job.
-- acct_gather_energy/ipmi - Add delay before retry on read error.
-- select/cons_res with GRES and multiple threads per core, fix possible
infinite loop.
-- proctrack/cgroup - Add cgroup create retry logic in case one step is
starting at the same time as another step is ending and the logic to create
and delete cgroups overlaps.
-- Improve setting of job wait "Reason" field.
-- Correct sbatch documentation and job_submit/pbs plugin "%j" is job ID,
not "%J" (which is job_id.step_id).
-- Improvements to sinfo performance, especially for large numbers of
partitions.
-- SlurmdDebug - Permit changes to slurmd debug level with "scontrol reconfig"
-- smap - Avoid invalid memory reference with hidden nodes.
-- Fix sacctmgr modify qos set preempt+/-=.
-- BLUEGENE - fix issue where node count wasn't set up correctly when srun
preforms the allocation, regression in 2.6.3.

"sbatch --depend=afterok:123_4 ...") or all elements of a job array (e.g.
"sbatch --depend=afterok:123 ...").
-- Add support for new options in sbatch qsub wrapper:
-W block=true (wait for job completion)
Clear PBS_NODEFILE environment variable
-- Fixed the MaxSubmitJobsPerUser limit in QOS which limited submissions
a job too early.
-- sched/wiki, sched/wiki2 - Fix to work with change logic introduced in
version 2.6.3 preventing Maui/Moab from starting jobs.
-- Updated the QOS limits documentation and man page.
* Changes in Slurm 2.6.3
========================
-- Add support for some new #PBS options in sbatch scripts and qsub wrapper:
-l accelerator=true|false (GPU use)
-l mpiprocs=# (processors per node)
-l naccelerators=# (GPU count)
-l select=# (node count)
-l ncpus=# (task count)
-v key=value (environment variable)
-W depend=opts (job dependencies, including "on" and "before" options)
-W umask=# (set job's umask)
-- Added qalter and qrerun commands to torque package.
-- Corrections to qstat logic: job CPU count and partition time format.
-- Add job_submit/pbs plugin to translate PBS job dependency options to the
extend possible (no support for PBS "before" options) and set some PBS
environment variables.
-- Add spank/pbs plugin to set a bunch of PBS environment variables.
-- Backported sh5util from master to 2.6 as there are some important
bugfixes and the new item extraction feature.
-- select/cons_res - Correct MacCPUsPerNode partition constraint for CR_Socket.

-- Fix issue when a user has held a job and then sets the begin time
into the future.
-- Scontrol - Enable changing a job's stdout file.
-- Fix issues where memory or node count of a srun job is altered while the
srun is pending. The step creation would use the old values and possibly
hang srun since the step wouldn't be able to be created in the modified
allocation.
-- Add support for new SchedulerParameters value of "bf_max_job_part", the
maximum depth the backfill scheduler should go in any single partition.
-- acct_gather/infiniband plugin - Correct packets_in/out values.
-- BLUEGENE - Don't ignore a conn-type request from the user.
-- BGQ - Force a request on a Q for a MESH to be a TORUS in a dimension that
can only be a TORUS (1).
-- Change max message length from 100MB to 1GB before generating "Insane
message length" error.
-- sched/backfill - Prevent possible memory corruption due to use of
bf_continue option and long running scheduling cycle (pending jobs could
have been cancelled and purged).
-- CRAY - fix AcceleratorAllocation depth correctly for basil 1.3
-- Created the environment variable SLURM_JOB_NUM_NODES for srun jobs and
updated the srun man page.
-- BLUEGENE/CRAY - Don't set env variables that pertain to a node when Slurm
isn't doing the launching.

file as a fatal error.
-- Fixed for if hours are specified as 0 the time days-0:min specification
is not parsed correctly.
-- switch/nrt - Fix for memory leak.
-- Subtract the PMII_COMMANDLEN_SIZE in contribs/pmi2/pmi2_api.c to prevent
certain implementation of snprintf() to segfault.
* Changes in Slurm 2.6.2
========================
-- Fix issue with reconfig and GrpCPURunMins
-- Fix of wrong node/job state problem after reconfig
-- Allow users who are coordinators update their own limits in the accounts
they are coordinators over.
-- BackupController - Make sure we have a connection to the DBD first thing
to avoid it thinking we don't have a cluster name.
-- Correct value of min_nodes returned by loading job information to consider
the job's task count and maximum CPUs per node.
-- If running jobacct_gather/none fix issue on unpacking step completion.
-- Reservation with CoreCnt: Avoid possible invalid memory reference.
-- sjstat - Add man page when generating rpms.
-- Make sure GrpCPURunMins is added when creating a user, account or QOS with
sacctmgr.
-- Fix for invalid memory reference due to multiple free calls caused by
job arrays submitted to multiple partitions.
-- Enforce --ntasks-per-socket=1 job option when allocating by socket.
-- Validate permissions of key directories at slurmctld startup. Report
anything that is world writable.
-- Improve GRES support for CPU topology. Previous logic would pick CPUs then
reject jobs that can not match GRES to the allocated CPUs. New logic first
filters out CPUs that can not use the GRES, next picks CPUs for the job,
and finally picks the GRES that best match those CPUs.
-- Switch/nrt - Prevent invalid memory reference when allocating single adapter
per node of specific adapter type
-- CRAY - Make Slurm work with CLE 5.1.1
-- Fix segfault if submitting to multiple partitions and holding the job.
-- Use MAXPATHLEN instead of the hardcoded value 1024 for maximum file path
lengths.
-- If OverTimeLimit is defined do not declare failed those jobs that ended
in the OverTimeLimit interval.
* Changes in Slurm 2.6.1
========================
-- slurmdbd - Allow job derived ec and comments to be modified by non-root
users.
-- Fix issue with job name being truncated to 24 chars when sending a mail
message.
-- Fix minor issues with spec file, missing files and including files
erroneously on a bluegene system.
-- sacct - fix --name and --partition options when using
accounting_storage/filetxt.
-- squeue - Remove extra whitespace of default printout.
-- BGQ - added head ppcfloor as an include dir when building.
-- BGQ - Better debug messages in runjob_mux plugin.
-- PMI2 Updated the Makefile.am to build a versioned library.
-- CRAY - Fix srun --mem_bind=local option with launch/aprun.
-- PMI2 Corrected buffer size computation in the pmi2_api.c module.
-- GRES accounting data wrong in database: gres_alloc, gres_req, and gres_used
fields were empty if the job was not started immediately.
-- Fix sbatch and srun task count logic when --ntasks-per-node specified,
but no explicit task count.
-- Corrected the hdf5 profile user guide and the acct_gather.conf
documentation.
-- IPMI - Fix Math bug getting new wattage.
-- Corrected the AcctGatherProfileType documentation in slurm.conf
-- Corrected the sh5util program to print the header in the csv file
only once, set the debug messages at debug() level, make the argument
check case insensitive and avoid printing duplicate \n.
-- If cannot collect energy values send message to the controller
to drain the node and log error slurmd log file.
-- Handle complete removal of CPURunMins time at the end of the job instead
of at multifactor poll.
-- sview - Add missing debug_flag options.
-- PGSQL - Notes about Postgres functionality being removed in the next
version of Slurm.
-- MYSQL - fix issue when rolling up usage and events happened when a cluster
was down (slurmctld not running) during that time period.
-- sched/wiki2 - Insure that Moab gets current CPU load information.
-- Prevent infinite loop in parsing configuration if including file containing
one blank line.
-- Fix pack and unpack between 2.6 and 2.5.
-- Fix job state recovery logic in which a job's accounting frequency was
not set. This would result in a value of 65534 seconds being used (the
equivalent of NO_VAL in uint16_t), which could result in the job being
requeued or aborted.
-- Validate a job's accounting frequency at submission time rather than
waiting for it's initiation to possibly fail.
-- Fix CPURunMins if a job is requeued from a failed launch.
-- Fix in accounting_storage/filetxt to correct start times which sometimes
could end up before the job started.
-- Fix issue with potentially referencing past an array in parse_time()
-- CRAY - fix issue with accelerators on a cray when parsing BASIL 1.3 XML.
-- Fix issue with a 2.5 slurmstepd locking up when talking to a 2.6 slurmd.
-- Add argument to priority plugin's priority_p_reconfig function to note
when the association and QOS used_cpu_run_secs field has been reset.
* Changes in Slurm 2.6.0
========================
-- Fix it so bluegene and serial systems don't get warnings over new NODEDATA
enum.
-- When a job is aborted send a message for any tasks that have completed.
-- Correction to memory per CPU calculation on system with threads and
allocating cores or sockets.
-- Requeue batch job if it's node reboots (used to abort the job).
-- Enlarge maximum size of srun's hostlist file.
-- IPMI - Fix first poll to get correct consumed_energy for a step.
-- Correction to job state recovery logic that could result in assert failure.
-- Record partial step accounting record if allocated nodes fail abnormally.
-- Accounting - fix issue where PrivateData=jobs or users could potentially
show information to users that had no associations on the system.
-- Make PrivateData in slurmdbd.conf case insensitive.
-- sacct/sstat - Add format option ConsumedEnergyRaw to print full energy
values.
* Changes in Slurm 2.6.0rc2
===========================
-- HDF5 - Fix issue with Ubuntu where HDF5 development headers are
overwritten by the parallel versions thus making it so we need handle
both cases.
-- ACCT_GATHER - handle suspending correctly for polling threads.
-- Make SLURM_DISTRIBUTION env var hold both types of distribution if
specified.
-- Remove hardcoded /usr/local from slurm.spec.
-- Modify slurmctld locking to improve performance under heavy load with
very large numbers of batch job submissions or job cancellations.
-- sstat - Fix issue where if -j wasn't given allow last argument to be checked
for as the job/step id.
-- IPMI - fix adjustment on poll when using EnergyIPMICalcAdjustment.
* Changes in Slurm 2.6.0rc1
===========================
-- Added helper script for launching symmetric and MIC-only MPI tasks within
SLURM (in contribs/mic/mpirun-mic).
-- Change maximum delay for state save from 2 secs to 5 secs. Make timeout
configurable at build time by defining SAVE_MAX_WAIT.
-- Modify slurmctld data structure locking to interleave read and write
locks rather than always favor write locks over read locks.
-- Added sacct format option of "ALL" to print all fields.
-- Deprecate the SchedulerParameters value of "interval" use "bf_interval"
instead as documented.
-- Add acct_gather_profile/hdf5 to profile jobs with hdf5
-- Added MaxCPUsPerNode partition configuration parameter. This can be
especially useful to schedule systems with GPUs.
-- Permit "scontrol reboot_node" for nodes in MAINT reservation.
-- Added "PriorityFlags" value of "SMALL_RELATIVE_TO_TIME". If set, the job's
size component will be based upon not the job size alone, but the job's
size divided by it's time limit.
-- Added sbatch option "--ignore-pbs" to ignore "#PBS" options in the batch
script.
-- Rename slurm_step_ctx_params_t field from "mem_per_cpu" to "pn_min_memory".
Job step now accepts memory specification in either per-cpu or per-node
basis.
-- Add ability to specify host repitition count in the srun hostfile (e.g.
"host1*2" is equivalent to "host1,host1").
* Changes in Slurm 2.6.0pre3
============================
-- Add milliseconds to default log message header (both RFC 5424 and ISO 8601
time formats). Disable milliseconds logging using the configure
parameter "--disable-log-time-msec". Default time format changes to
ISO 8601 (without time zone information). Specify "--enable-rfc5424time"
to restore the time zone information.
-- Add username (%u) to the filename pattern in the batch script.
-- Added options for front end nodes of AllowGroups, AllowUsers, DenyGroups,
and DenyUsers.
-- Fix sched/backfill logic to initiate jobs with maximum time limit over the
partition limit, but the minimum time limit permits it to start.
-- gres/gpu - Fix for gres.conf file with multiple files on a single line
using a slurm expression (e.g. "File=/dev/nvidia[0-1]").
-- Replaced ipmi.conf with generic acct_gather.conf file for all acct_gather
plugins. For those doing development to use this follow the model set
forth in the acct_gather_energy_ipmi plugin.
-- Added more options to update a step's information
-- Add DebugFlags=ThreadID which will print the thread id of the calling
thread.
-- CRAY - Allocate whole node (CPUs) in reservation despite what the
user requests. We have found any srun/aprun afterwards will work on a
subset of resources.
* Changes in Slurm 2.6.0pre2
============================
-- Do not purge inactive interactive jobs that lack a port to ping (added
for MR+ operation).
-- Advanced reservations with hostname and core counts now supports asymetric
reservations (e.g. specific different core count for each node).
-- Added slurmctld/dynalloc plugin for MapReduce+ support.
-- Added "DynAllocPort" configuration parameter.
-- Added partition paramter of SelectTypeParameters to override system-wide
value.
-- Added cr_type to partition_info data structure.
-- Added allocated memory to node information available (within the existing
select_nodeinfo field of the node_info_t data structure). Added Allocated
Memory to node information displayed by sview and scontrol commands.
-- Make sched/backfill the default scheduling plugin rather than sched/builtin
(FIFO).
-- Added support for a job having different priorities in different partitions.
-- Added new SchedulerParameters configuration parameter of "bf_continue"
which permits the backfill scheduler to continue considering jobs for
backfill scheduling after yielding locks even if new jobs have been
submitted. This can result in lower priority jobs from being backfill
scheduled instead of newly arrived higher priority jobs, but will permit
more queued jobs to be considered for backfill scheduling.
-- Added support to purge reservation records from accounting.
-- Cray - Add support for Basil 1.3
* Changes in SLURM 2.6.0pre1
============================
-- Add "state" field to job step information reported by scontrol.
-- Notify srun to retry step creation upon completion of other job steps
rather than polling. This results in much faster throughput for job step
execution with --exclusive option.
-- Added "ResvEpilog" and "ResvProlog" configuration parameters to execute a
program at the beginning and end of each reservation.
-- Added "slurm_load_job_user" function. This is a variation of
"slurm_load_jobs", but accepts a user ID argument, potentially resulting
in substantial performance improvement for "squeue --user=ID"
-- Added "slurm_load_node_single" function. This is a variation of
"slurm_load_nodes", but accepts a node name argument, potentially resulting
in substantial performance improvement for "sinfo --nodes=NAME".
-- Added "HealthCheckNodeState" configuration parameter identify node states
on which HealthCheckProgram should be executed.
-- Remove sacct --dump --formatted-dump options which were deprecated in
2.5.
-- Added support for job arrays (phase 1 of effort). See "man sbatch" option
-a/--array for details.
-- Add new AccountStorageEnforce options of 'nojobs' and 'nosteps' which will
allow the use of accounting features like associations, qos and limits but
not keep track of jobs or steps in accounting.
-- Cray - Add new cray.conf parameter of "AlpsEngine" to specify the
communication protocol to be used for ALPS/BASIL.
-- select/cons_res plugin: Correction to CPU allocation count logic in for
cores without hyperthreading.
-- Added new SelectTypeParameter value of "CR_ALLOCATE_FULL_SOCKET".
-- Added PriorityFlags value of "TICKET_BASED" and merged priority/multifactor2
plugin into priority/multifactor plugin.
-- Add "KeepAliveTime" configuration parameter controlling how long sockets
used for srun/slurmstepd communications are kept alive after disconnect.
-- Added SLURM_SUBMIT_HOST to salloc, sbatch and srun job environment.
-- Added SLURM_ARRAY_TASK_ID to environment of job array.
-- Added squeue --array/-r option to optimize output for job arrays.
-- Added "SlurmctldPlugstack" configuration parameter for generic stack of
slurmctld daemon plugins.
-- Removed contribs/arrayrun tool. Use native support for job arrays.
-- Modify default installation locations for RPMs to match "make install":
_prefix /usr/local
_slurm_sysconfdir %{_prefix}/etc/slurm
_mandir %{_prefix}/share/man
_infodir %{_prefix}/share/info
-- Add acct_gather_energy/ipmi which works off freeipmi for energy gathering
* Changes in Slurm 2.5.8
========================
-- Fix for slurmctld segfault on NULL front-end reason field.
-- Avoid gres step allocation errors when a job shrinks in size due to either
down nodes or explicit resizing. Generated slurmctld errors of this type:
"step_test ... gres_bit_alloc is NULL"
-- Fix bug that would leak memory and over-write the AllowGroups field if on
"scontrol reconfig" when AllowNodes is manually changed using scontrol.
-- Get html/man files to install in correct places with rpms.
-- Remove --program-prefix from spec file since it appears to be added by
default and appeared to break other things.
-- Updated the automake min version in autogen.sh to be correct.
-- Select/cons_res - Correct total CPU count allocated to a job with
--exclusive and --cpus-per-task options
-- switch/nrt - Don't allocate network resources unless job step has 2+ nodes.
-- select/cons_res - Avoid extraneous "oversubscribe" error messages.
-- Reorder get config logic to avoid deadlock.
-- Enforce QOS MaxCPUsMin limit when job submission contains no user-specified
time limit.
-- EpilogSlurmctld pthread is passed required arguments rather than a pointer
to the job record, which under some conditions could be purged and result
in an invalid memory reference.
* Changes in Slurm 2.5.7
========================
-- Fix for linking to the select/cray plugin to not give warning about
undefined variable.
-- Add missing symbols to the xlator.h
-- Avoid placing pending jobs in AdminHold state due to backfill scheduler
interactions with advanced reservation.
-- Accounting - make average by task not cpu.
-- CRAY - Change logging of transient ALPS errors from error() to debug().
-- POE - Correct logic to support poe option "-euidevice sn_all" and
"-euidevice sn_single".

-- POE - With the srun --launch-cmd option, report proper task count when
the --cpus-per-task option is used without the --ntasks option.
-- POE - Fix logic binding tasks to CPUs.
-- sview - Fix race condition where new information could of slipped past
the node tab and we didn't notice.
-- Accounting - Fix an invalid memory read when slurmctld sends data about
start job to slurmdbd.
-- If a prolog or epilog failure occurs, drain the node rather than setting it
down and killing all of its jobs.
-- Priority/multifactor - Avoid underflow in half-life calculation.
-- POE - pack missing variable to allow fanout (more than 32 nodes)
-- Prevent clearing reason field for pending jobs. This bug was introduced in
v2.5.5 (see "Reject job at submit time ...").
-- BGQ - Fix issue with preemption on sub-block jobs where a job would kill
all preemptable jobs on the midplane instead of just the ones it needed to.
-- switch/nrt - Validate dynamic window allocation size.
-- BGQ - When --geo is requested do not impose the default conn_types.
-- CRAY - Support CLE 4.2.0
-- RebootNode logic - Defers (rather than forgets) reboot request with job
running on the node within a reservation.
-- switch/nrt - Correct network_id use logic. Correct support for user sn_all
and sn_single options.
-- sched/backfill - Modify logic to reduce overhead under heavy load.
-- Fix job step allocation with --exclusive and --hostlist option.

progressing, holding job #"
-- checkpoint/blcr - Reset max_nodes from zero to NO_VAL on job restart.
-- launch/poe - Fix for hostlist file support with repeated host names.
-- priority/multifactor2 - Prevent possible divide by zero.
-- srun - Don't check for executable if --test-only flag is used.
-- energy - On a single node only use the last task for gathering energy.
Since we don't currently track energy usage per task (only per step).
Otherwise we get double the energy.
* Changes in Slurm 2.5.6
========================
-- Gres fix for requeued jobs.
-- Gres accounting - Fix regression in 2.5.5 for keeping track of gres
requested and allocated.
* Changes in Slurm 2.5.5
========================
-- Fix for sacctmgr add qos to handle the 'flags' option.
-- Export SLURM_ environment variables from sbatch, even if "--export"
option does not explicitly list them.
-- If node is in more than one partition, correct counting of allocated CPUs.

-- Cray - Disable enforcement of MaxTasksPerNode, which is not applicable
with launch/aprun.
-- Accounting - When rolling up data from past usage ignore "idle" time from
a reservation when it has the "Ignore_Jobs" flag set. Since jobs could run
outside of the reservation in it's nodes without this you could have
double time.
-- Accounting - Minor fix to avoid reuse of variable erroneously.
-- Reject job at submit time if the node count is invalid. Previously such a
job submitted to a DOWN partition would be queued.
-- Purge vestigial job scripts when the slurmd cold starts or slurmstepd
terminates abnormally.
-- Add support for FreeBSD.
-- Add sanity check for NULL cluster names trying to register.
-- BGQ - Push action 'D' info to scontrol for admins.
-- Reset a job's reason from PartitionDown when the partition is set up.
-- BGQ - Handle issue where blocks would have a pending job on them and
while it was free cnodes would go into software error and kill the job.
-- BGQ - Fix issue where if for some reason we are freeing a block with
a pending job on it we don't kill the job.
-- BGQ - Fix race condition were a job could of been removed from a block
without it still existing there. This is extremely rare.
-- BGQ - Fix for when a step completes in Slurm before the runjob_mux notifies
the slurmctld there were software errors on some nodes.
-- BGQ - Fix issue on state recover if block states are not around
and when reading in state from DB2 we find a block that can't be created.
You can now do a clean start to rid the bad block.
-- Modify slurmdbd to retransmit to slurmctld daemon if it is not responding.
-- BLUEGENE - Fix issue where when doing backfill preemptable jobs were
never looked at to determine eligibility of backfillable job.

-- CRAY - Fix memory issue with reading in the cray.conf file.
-- CRAY - If hostlist is given with srun make sure the node count is the same
as the hosts given.
-- CRAY - If task count specified, but no tasks-per-node, then set the tasks
per node in the BASIL reservation request.
-- CRAY - fix issue with --mem option not giving correct amount of memory
per cpu.
-- CRAY - Fix if srun --mem is given outside an allocation to set the
APRUN_DEFAULT_MEMORY env var for aprun. This scenario will not display
the option when used with --launch-cmd.
-- Change sview to use GMutex instead of GStaticMutex

cpu count would be reflected correctly.
-- BGQ - fix for handling half rack system in STATIC of OVERLAP mode to
implicitly create full system block.
-- CRAY - Dynamically create BASIL XML buffer to resize as needed.
-- Fix checking if QOS limit MaxCPUMinsPJ is set along with DenyOnLimit to
deny the job instead of holding it.
-- Make sure on systems that use a different launcher than launch/slurm not
to attempt to signal tasks on the frontend node.
-- Cray - when a step is requested count other steps running on nodes in the
allocation as taking up the entire node instead of just part of the node
allocated. And always enforce exclusive on a step request.
-- Cray - display correct nodelist, node/cpu count on steps.
* Changes in Slurm 2.5.4
========================
-- Fix bug in PrologSlurmctld use that would block job steps until node
responds.
-- CRAY - If a partition has MinNodes=0 and a batch job doesn't request nodes
put the allocation to 1 instead of 0 which prevents the allocation to
happen.
-- Better debug when the database is down and using the --cluster option in
the user commands.
-- When asking for job states with sacct, default to 'now' instead of midnight
of the current day.

a base value of zero.
-- Fix for priority/multifactor2 plugin to not assert when configured with
--enable-debug.
-- Select/cons_res - If the job request specified --ntasks-per-socket and the
allocation using is cores, then pack the tasks onto the sockets up to the
specified value.
-- BGQ - If a cnode goes into an 'error' state and the block containing the
cnode does not have a job running on it do not resume the block.

at least 3.5.0. This avoids a stack overflow when running jobs on
more than 120k nodes.
-- BLUEGENE - If we made a block that isn't runnable because of a overlapping
block, destroy it correctly.
-- Switch/nrt - Dynamically load libnrt.so from within the plugin as needed.
This eliminates the need for libnrt.so on the head node.
-- BLUEGENE - Fix in reservation logic that could cause abort.
* Changes in SLURM 2.5.1
========================
-- Correction to hostlist sorting for hostnames that contain two numeric
components and the first numeric component has various sizes (e.g.
"rack9blade1" should come before "rack10blade1")
-- BGQ - Only poll on initialized blocks instead of calling getBlocks on
each block independently.

node).
-- Add launch and acct_gather_energy plugins to RPMs.
-- Restore support for srun "--mpi=list" option.
-- CRAY - Introduce step accounting for a Cray.

instead of putting 0's into the database we put NO_VALS and have sacct
figure out jobacct_gather wasn't used.
-- Cray - Prevent calling basil_confirm more than once per job using a flag.
-- Fix bug with topology/tree and job with min-max node count. Now try to
get max node count rather than minimizing leaf switches used.

task count is not a multiple of the node count. Work by Hongjia Cao, NUDT.
-- Completed integration with IBM Parallel Environment including POE and IBM's
NRT switch library.

a reservation and automatically change the reservation when nodes are
added to or removed from the reservation. Based upon work by
Bill Brophy, Bull.

nodes. Current limiations: homogeneous cluster, nodes idle when reservation
created, and no more than one reservation per node. Code is still under
development. Work by Alejandro Lucero Palau, et. al, BSC.
-- Add DebugFlag of Switch to log switch plugin details.
-- Correct job node_cnt value in job completion plugin when job fails due to
down node. Previously was too low by one.
-- Add new srun option --cpu-freq to enable user control over the job's CPU
frequency and thus it's power consumption. NOTE: cpu frequency is not
currently preserved for jobs being suspended and later resumed. Work by
Don Albert, Bull.
-- Add node configuration information about "boards" and optimize task
placement on minimum number of boards. Work by Rod Schultz, Bull.

you query against that with -N and -E you will get all jobs during that
time instead of only the ones running on -N.
-- BGP - Fix for HTC mode
-- Accounting - If a job start message fails to the SlurmDBD reset the db_inx
so it gets sent again. This isn't a major problem since the start will
happen when the job ends, but this does make things cleaner.
-- If an salloc is waiting for an allocation to happen and is canceled by the
user mark the state canceled instead of completed.
-- Fix issue in accounting if a user puts a '\' in their job name.
-- Accounting - Fix for if asking for users or accounts that were deleted
with associations get the deleted associations as well.
-- BGQ - Handle shared blocks that need to be removed and have jobs running
on them. This should only happen in extreme conditions.
-- Fix inconsistency for hostlists that have more than 1 range.
-- BGQ - Add mutex around recovery for the Real Time server to avoid hitting
DB2 so hard.
-- BGQ - If an allocation exists on a block that has a 'D' action on it fail
job on future step creation attempts.
* Changes in SLURM 2.4.4
========================
-- BGQ - minor fix to make build work in emulated mode.
-- BGQ - Fix if large block goes into error and the next highest priority jobs
are planning on using the block. Previously it would fail those jobs
erroneously.
-- BGQ - Fix issue when a cnode going to an error (not SoftwareError) state
with a job running or trying to run on it.
-- Execute slurm_spank_job_epilog when there is no system Epilog configured.
-- Fix for srun --test-only to work correctly with timelimits
-- BGQ - If a job goes away while still trying to free it up in the
database, and the job is running on a small block make sure we free up
the correct node count.
-- BGQ - Logic added to make sure a job has finished on a block before it is
purged from the system if its front-end node goes down.
-- Modify strigger so that a filter option of "--user=0" is supported.
-- Correct --mem-per-cpu logic for core or socket allocations with multiple
threads per core.
-- Fix for older < glibc 2.4 systems to use euidaccess() instead of eaccess().
-- BLUEGENE - Do not alter a pending job's node count when changing it's
partition.
-- BGQ - Add functionality to make it so we track the actions on a block.
This is needed for when a free request is added to a block but there are
jobs finishing up so we don't start new jobs on the block since they will
fail on start.
-- BGQ - Fixed InactiveLimit to work correctly to avoid scenarios where a
user's pending allocation was started with srun and then for some reason
the slurmctld was brought down and while it was down the srun was removed.
-- Fixed InactiveLimit math to work correctly
-- BGQ - Add logic to make it so blocks can't use a midplane with a nodeboard
in error for passthrough.
-- BGQ - Make it so if a nodeboard goes in error any block using that midplane
for passthrough gets removed on a dynamic system.
-- BGQ - Fix for printing realtime server debug correctly.
-- BGQ - Cleaner handling of cnode failures when reported through the runjob
interface instead of through the normal method.
-- smap - spread node information across multiple lines for larger systems.
-- Cray - Defer salloc until after PrologSlurmctld completes.
-- Correction to slurmdbd communications failure handling logic, incorrect
error codes returned in some cases.
* Changes in SLURM 2.4.3
========================
-- Accounting - Fix so complete 32 bit numbers can be put in for a priority.
-- cgroups - fix if initial directory is non-existent SLURM creates it
correctly. Before the errno wasn't being checked correctly
-- BGQ - fixed srun when only requesting a task count and not a node count
to operate the same way salloc or sbatch did and assign a task per cpu
by default instead of task per node.
-- Fix salloc --gid to work correctly. Reported by Brian Gilmer
-- BGQ - fix smap to set the correct default MloaderImage
-- BLUEGENE - updated documentation.
-- Close the batch job's environment file when it contains no data to avoid
leaking file descriptors.
-- Fix sbcast's credential to last till the end of a job instead of the
previous 20 minute time limit. The previous behavior would fail for
large files 20 minutes into the transfer.
-- Return ESLURM_NODES_BUSY rather than ESLURM_NODE_NOT_AVAIL error on job
submit when required nodes are up, but completing a job or in exclusive
job allocation.
-- Add HWLOC_FLAGS so linking to libslurm works correctly
-- BGQ - If using backfill and a shared block is running at least one job
and a job comes through backfill and can fit on the block without ending
jobs don't set an end_time for the running jobs since they don't need to
end to start the job.
-- Initialize bind_verbose when using task/cgroup.
-- BGQ - Fix for handling backfill much better when sharing blocks.
-- BGQ - Fix for making small blocks on first pass if not sharing blocks.
-- BLUEGENE - Remove force of default conn_type instead of leaving NAV
when none are requested. The Block allocator sets it up temporarily so
this isn't needed.
-- BLUEGENE - Fix deadlock issue when dealing with bad hardware if using
static blocks.
-- Fix to mysql plugin during rollup to only query suspended table when jobs
reported some suspended time.
-- Fix compile with glibc 2.16 (Kacper Kowalik)
-- BGQ - fix for deadlock where a block has error on it and all jobs
running on it are preemptable by scheduling job.
-- proctrack/cgroup: Exclude internal threads from "scontrol list pids".
Patch from Matthieu Hautreux, CEA.
-- Memory leak fixed for select/linear when preempting jobs.
-- Fix if updating begin time of a job to update the eligible time in
accounting as well.
-- BGQ - make it so you can signal steps when signaling the job allocation.
-- BGQ - Remove extra overhead if a large block has many cnode failures.
-- Priority/Multifactor - Fix issue with age factor when a job is estimated to
start in the future but is able to run now.
-- CRAY - update to work with ALPS 5.1
-- BGQ - Handle issue of speed and mutexes when polling instead of using the
realtime server.
-- BGQ - Fix minor sorting issue with sview when sorting by midplanes.
-- Accounting - Fix for handling per user max node/cpus limits on a QOS
correctly for current job.
-- Update documentation for -/+= when updating a reservation's
users/accounts/flags
-- Update pam module to work if using aliases on nodes instead of actual
host names.
-- Correction to task layout logic in select/cons_res for job with minimum
and maximum node count.
-- BGQ - Put final poll after realtime comes back into service to avoid
having the realtime server go down over and over again while waiting
for the poll to finish.
-- task/cgroup/memory - ensure that ConstrainSwapSpace=no is correctly
handled. Work by Matthieu Hautreux, CEA.
-- CRAY - Fix for sacct -N option to work correctly
-- CRAY - Update documentation to describe installation from rpm instead
or previous piecemeal method.
-- Fix sacct to work with QOS' that have previously been deleted.
-- Added all available limits to the output of sacctmgr list qos
* Changes in SLURM 2.4.2
========================
-- BLUEGENE - Correct potential deadlock issue when hardware goes bad and
there are jobs running on that hardware.
-- If job is submitted to more than one partition, it's partition pointer can
be set to an invalid value. This can result in the count of CPUs allocated
on a node being bad, resulting in over- or under-allocation of its CPUs.
Patch by Carles Fenoy, BSC.
-- Fix bug in task layout with select/cons_res plugin and --ntasks-per-node
option. Patch by Martin Perry, Bull.
-- BLUEGENE - remove race condition where if a block is removed while waiting
for a job to finish on it the number of unused cpus wasn't updated
correctly.
-- BGQ - make sure we have a valid block when creating or finishing a step
allocation.
-- BLUEGENE - If a large block (> 1 midplane) is in error and underlying
hardware is marked bad remove the larger block and create a block over
just the bad hardware making the other hardware available to run on.
-- BLUEGENE - Handle job completion correctly if an admin removes a block
where other blocks on an overlapping midplane are running jobs.
-- BLUEGENE - correctly remove running jobs when freeing a block.
-- BGQ - correct logic to place multiple (< 1 midplane) steps inside a
multi midplane block allocation.
-- BGQ - Make it possible for a multi midplane allocation to run on more
than 1 midplane but not the entire allocation.
-- BGL - Fix for syncing users on block from Tim Wickberg
-- Fix initialization of protocol_version for some messages to make sure it
is always set when sending or receiving a message.
-- Reset backfilled job counter only when explicitly cleared using scontrol.
Patch from Alejandro Lucero Palau, BSC.
-- BLUEGENE - Fix for handling blocks when a larger block will not free and
while it is attempting to free underlying hardware is marked in error
making small blocks overlapping with the freeing block. This only
applies to dynamic layout mode.
-- Cray and BlueGene - Do not treat lack of usable front-end nodes when
slurmctld deamon starts as a fatal error. Also preserve correct front-end
node for jobs when there is more than one front-end node and the slurmctld
daemon restarts.
-- Correct parsing of srun/sbatch input/output/error file names so that only
the name "none" is mapped to /dev/null and not any file name starting
with "none" (e.g. "none.o").
-- BGQ - added version string to the load of the runjob_mux plugin to verify
the current plugin has been loaded when using runjob_mux_refresh_config
-- CGROUPS - Use system mount/umount function calls instead of doing fork
exec of mount/umount from Janne Blomqvist.
-- BLUEGENE - correct start time setup when no jobs are blocking the way
from Mark Nelson
-- Fixed sacct --state=S query to return information about suspended jobs
current or in the past.
-- FRONTEND - Made error warning more apparent if a frontend node isn't
configured correctly.
-- BGQ - update documentation about runjob_mux_refresh_config which works
correctly as of IBM driver V1R1M1 efix 008.

paexec: Fix for segfault seen on Linux
|
|
This release of paexec was successfully tested on the following
platforms: NetBSD-6.1/amd64, OpenBSD-5.3/i386, FreeBSD-8.3/i386,
Solaris-10/sparc, Solaris-11/amd64 and diverse Linux/{i386,amd64}.
paexec is now selfcontained, libmaa is not needed anymore.
Presentation paexec.pdf was added to presentation/. I hope it will
help easier understand how "paexec" works. It is installed to
${DOCDIR}.
paexec:
- POSIX-2008 getline(3) is used for reading lines
instead of home-made function.
- t '' is equivalent to "no transport", spaces are trimmed.
- "-n +NNN" has higher priority than -t, i.e. if they both are
specified, transport is ignored.
- Fix for -W1.
- Environment variable PAEXEC_EOT was introduced.
- Option -y was added to paexec(1) and paexec_reorder(1).
- Option -C was added to paexec(1).
paexec_reorder:
- Option -x was added to paexec_reorder(1).
A number of fixes and improvements in regression tests.
|
|
2.7.3.31 - 2012-07-04
---------------------
- Recent changes broke support for running without C extension (Issue #57).
