- max_memory_per_child was measured in kilobytes on Linux, but bytes on
*BSD/MacOS, it's now always kilobytes.
- Windows: Adds support for max_memory_per_child, but requires the
``psutil`` package to be installed.
- Fixed bug in ForkingPickler.loadbuf, where it tried to pass
a BytesIO instance directly to ``pickle.loads`` on Python 2.7.

Version 1.11.2
--------------
* Improve support for Intel Knights Landing Xeon Phi on Linux:
+ Group local NUMA nodes of normal memory (DDR) and high-bandwidth memory
(MCDRAM) together through "Cluster" groups so that the local MCDRAM is
easy to find.
- See "How do I find the local MCDRAM NUMA node on Intel Knights
Landing Xeon Phi?" in the documentation.
- For uniformity across all KNL configurations, always have a NUMA node
object even if the host is UMA.
+ Fix the detection of the memory-side cache:
- Add the hwloc-dump-hwdata superuser utility to dump SMBIOS information
into /var/run/hwloc/ as root during boot, and load this dumped
information from the hwloc library at runtime.
- See "Why do I need hwloc-dump-hwdata for caches on Intel Knights
Landing Xeon Phi?" in the documentation.
Thanks to Grzegorz Andrejczuk for the patches and for the help.
* The x86 and linux backends may now be combined for discovering CPUs
through x86 CPUID and memory from the Linux kernel.
This is useful for working around buggy CPU information reported by Linux
(for instance the AMD Bulldozer/Piledriver bug below).
Combination is enabled by passing HWLOC_COMPONENTS=x86 in the environment.
* Fix L3 cache sharing on AMD Opteron 63xx (Piledriver) and 62xx (Bulldozer)
in the x86 backend. Thanks to many users who helped.
* Fix the overzealous L3 cache sharing fix added to the x86 backend in 1.11.1
for AMD Opteron 61xx (Magny-Cours) processors.
* The x86 backend may now add the info attribute Inclusive=0 or 1 to caches
it discovers, or to caches discovered by other backends earlier.
Thanks to Guillaume Beauchamp for the patch.
* Fix the management on alloc_membind() allocation failures on AIX, HP-UX
and OSF/Tru64.
* Fix spurious failures to load with ENOMEM on AIX in case of Misc objects
below PUs.
* lstopo improvements in X11 and Windows graphical mode:
+ Add + - f 1 shortcuts to manually zoom-in, zoom-out, reset the scale,
or fit the entire window.
+ Display all keyboard shortcuts in the console.
* Debug messages may be disabled at runtime by passing HWLOC_DEBUG_VERBOSE=0
in the environment when --enable-debug was passed to configure.
* Add a FAQ entry "What are these Group objects in my topology?".

* Changes in pdsh-2.31 (2013-11-07)
===================================
-- Fix issue 56: slurm: Allow mixed use of -P, -w and -j options.
-- Fix issue 59: pdsh very slow when using a few thousand hosts
and genders.
-- testsuite: Expanded tests for genders module (Pythagoras
Watson)
* Changes in pdsh-2.30 (2013-03-02)
===================================
-- Fix issue 55: genders -X option removes more hosts than
expected.
(This was a generic fix for hostname matching, so it probably
affected -x and other options as well.)
-- testsuite: Add test for issue 55.

Upstream changes:
20160822
- Bug fixes and man page updates.
20160722
- env_parallel is now ready for wider testing. It is still beta
quality.
- env_parallel is heavily modified for all shells and testing has been
increased.
- Selectively choosing what to export using --env now works for
env_parallel (bash, csh, fish, ksh, pdksh, tcsh, zsh).
- --round-robin now gives more work to a job that processes faster
instead of same amount to all jobs.
- --pipepart works on block devices on GNU/Linux.
- Bug fixes and man page updates.
20160622
- $PATH can now be exported using --env PATH. Useful if GNU Parallel
is not in your path on remote machines.
- If --block is left out, --pipepart will use a block size that will
result in 10 jobs per jobslot.
- Bug fixes and man page updates.
20160522
- niceload --net pauses the program if the internet connection is
overloaded.
- Bug fixes and man page updates.
20160422
- :::+ and ::::+ work like ::: and :::: but links this input source to
the previous input source in a --xapply fashion. Contrary to
--xapply values do not wrap: The shortest input source determines
the length.
- --line-buffer --keep-order now outputs continously from the oldest
job still running. This is more what you would expect than the
earlier behaviour where --keep-order had no effect with
--line-buffer.
- env_parallel supports tcsh, csh, pdksh. In fish it now supports
arrays. In csh/tcsh it now supports variables, aliases, and arrays
with no special chars. In pdksh it supports aliases, functions,
variables, and arrays.
- Function exporting on Mac OS X works around old Bash version.
- Better CPU detection on OpenIndiana.
- Bug fixes and man page updates.
20160322
- env_parallel is a function that exports the environment (functions,
aliases, variables, and arrays) to GNU Parallel. Run 'man
env_parallel' for details.
- niceload --prg now searches for substrings if no process with the
name is found.
- Bug fixes and man page updates.
20160222
- Bug fixes and man page updates.
20160122
- --sql DBURL uses DBURL as storage for jobs and output. It does not
run any jobs so it requires at least one --sqlworker. DBURL must
point to a table.
- --sqlworker DBURL gets jobs from DBURL and stores the result back to
DBURL.
- --sqlandworker is a shorthand for --sql and --sqlworker.
- --sqlworker requires the output of a single job to fit in memory.
- --results now also saves a file called 'seq' containing the sequence
number.
- If $PARALLEL_ENV is a file, then that file will be read into
$PARALLEL_ENV.
- man parallel_tutorial has been given an overhaul.
- --workdir now accepts replacementstrings.
- Bug fixes and man page updates.
20151222
- --transfer is now an alias for --transferfile {}.
- --transferfile works like --transfer, but takes an argument like
--return. This makes it possible to combine transferring files
with multiple input sources: parallel -S server --tf {1} wc {2}
{1} ::: * ::: -l -w -c
- total_jobs() can now be used in {= =}: parallel echo job {#} of '{=
$_=total_jobs() =}' ::: {1..50}
- Bug fixes and man page updates.
20151122
- Bug fixes and man page updates.
20151022
- --plus makes it possible to use {##} as a shorthand for
{= $_=$Global::JobQueue->total_jobs() =} which gives the the number
of jobs to run in total.
- {= $_=$Global::JobQueue->total_jobs() =} is incompatible with -X,
-m, and --xargs.
- GNU Parallel is now mostly compatible with lsh
(http://www.lysator.liu.se/~nisse/lsh/) and somewhat compatible with
autossh (http://www.harding.motd.ca/autossh/).
- --workdir ... now also works when run locally.
- Bug fixes and man page updates.
20150922
- Bug fixes and man page updates.
20150822
- If $job->skip() is called in {= =} the job will not be run.
- @arg can now be used in {= =}: parallel echo '{= $arg[2] < 5 and
$_="j" =}' ::: 1 2 3 ::: 4 5 6
- Bug fixes and man page updates.
20150722
- If a record fits in a block, --block only reads upto the size of
--block. If not: --block reads a full --block more.
- Due to widely spread distributions still using --tollef even after a
year of being retired following a year of being obsolete, --tollef
now gives an error unless used with --gnu.
- --nice now uses a perl wrapper instead of the nice command.
- Bug fixes and man page updates.
20150622
- --halt has been rewritten completely. You can now combine
percentages with success or fail. See the man page.
- Exit values 102..254 have been removed. 101 means more than 100 jobs
failed.
- Killing through --timeout, --memfree, or --halt is now done as a
process group.
- --termseq determines which signals are sent when a job is killed.
- An empty argument would previously cause no string to be
inserted. This is now changed to '' being inserted, thus prepending
a space to the output of: parallel echo {} b ::: ''
- $PARALLEL_ENV can now be set to an environment prepending the
command. Used in env_parallel as mentioned in the manpage.
- --retry-failed will retry all failed jobs in a joblog. It will
ignore any command given.
- --ssh and $PARALLEL_SSH can be used to set the command used for
ssh. The command is assumed to behave the same way as ssh.
- --fifo now works in csh, too.
- Q(...) can be used in {= =} to shell quote a string.
- Bug fixes and man page updates.
20150522
- Security: The security issue for --sshlogin + --fifo/--cat has been
fixed. Thereby all issues with
http://lists.gnu.org/archive/html/parallel/2015-04/msg00045.html
have been fixed.
- Security: After further security analysis the issue fixed in
20150422 also fixed the problem for --tmux.
- Bug fixes and man page updates.
20150422
New in this release:
- Security fix. An attacker on the local system could make you
overwrite one of your own files with a single byte. The problem
exist when you use --compress or --tmux or --pipe or --cat or
--fifo. The attacker must figure out the randomly chosen file name
and create a symlink within a time window of 15 ms.
- --shuf will generate all jobs, and shuffle them before running
them. This is useful to get a quick preview of the results before
running the full batch.
- Bug fixes and man page updates.
20150322
New in this release:
- --number-of-cores respects 'taskset' on GNU/Linux.
- --joblog --pipe gives the data send and received in the log.
- Bug fixes and man page updates.
20150222
- --tmux has gotten a major overhaul.
- Bug fixes and man page updates.
20150122
- Remote jobs now send stderr (standard error) to stderr (standard
error) instead of stdout (standard output).
- Remote execution command is now packed using base64 encoded
bzip2. This means that big environments (app. 100 KB) can be
transferred. This change makes remote execution alpha quality.
- --semaphoretimeout now takes a negative value. This means give up if
the semaphore is not gotten within the timeout.
- --halt -1 and -2 now means halt if a job succeeds (so the opposite
of 1 and 2).
- --no-keep-order will reverse --keep-order.
- Bash's second fix of shellshock caused --env to break again when
exporting functions. This has been fixed again.
- A semibig refactoring of big functions. All non-trivial functions
are now less than 100 lines. The refactoring makes this release beta
quality.
- A description of the design decisions for GNU Parallel can be found
in 'man parallel_design'.
- A bug fix in replacement strings caused rewrite of the replacement
function. This makes use of replacement strings alpha quality.
- Bug fixes and man page updates.
20141122
- Remote systems can be divided into hostgroups (e.g. web and db) by
prepending '@groupname/' to the sshlogin. Multiple groups can be
given by separating groups with '+'. E.g. @web/www1 @web+db/www2
@db/mariadb
- Remote execution can be restricted to servers that are part of one
or more groups by '@groupname' as an sshlogin. Multiple groups can
be given by separating groups with '+'. E.g. -S @web or -S @db+web
- With --hostgroup you can restrict arguments to certain hostgroups by
appending '@groupname' to the argument. Multiple groups can be
given by separating groups with '+'. E.g. my_web_arg@web
db-or-web-arg@db+web db-only-arg@db Thanks to Michel Courtine for
developing a prototype for this.
- Bug fixes and man page updates.
20141022
- --env was changed to deal with Bash's new way of exporting a function.
- Bug fixes and man page updates.
20140922
- If the file give as --sshloginfile is changed it will be re-read
when a job finishes though at most once per second. This makes it
possible to add and remove hosts while running.
20140822
- GNU Parallel now uses the same shell it was started from as the
command shell for local jobs. So if GNU Parallel is started from
tcsh it will use tcsh as its shell even if the login $SHELL is
different. For remote jobs the login $SHELL will be used.
- The whole current environment in bash can be copied by using a shell
wrapper function (Search manual for env_parallel).
- --plus adds the replacement strings {+/} {+.} {+..} {+...} {..}
{...} {/..} {/...}. The idea being that '+foo' matches the opposite
of 'foo' and {} = {+/}/{/} = {.}.{+.} = {+/}/{/.}.{+.} = {..}.{+..}
= {+/}/{/..}.{+..} = {...}.{+...} = {+/}/{/...}.{+...}
- GNU Parallel now deals correctly with the combination
rsync-3.1.X-client and rsync-2.5.7-server
- Bug fixes and man page updates.
20140722
- {= perl expression =} can be used as replacement string. The
expression should modify $_. E.g. {= s/\.gz$// =} to remove .gz from
the string. This makes replacement strings extremely flexible.
- Positional perl expressions (similar to {2}) are given as {=2 perl
expression=} where 2 is the position.
- One small backwards incompatibility: {1}_{2} will replace {2} with
the empty string if there is only one argument. Previously {2} would
have been left untouched.
- Replacement strings can be defined using --rpl. E.g. parallel --rpl
'{.gz} s/\.gz$//' echo {.gz} ::: *.gz
- The parenthesis around {= perl expression =} can be changed with
--parens.
- --tmux will direct the output to a tmux session instead of
files. Each running jobs will be in its own window.
- --halt 10% will stop spawning new jobs if 10% failed so far.
- Bug fixes and man page updates.
20140622
- --shebang and --shebang-wrap now works on FreeBSD.
- --pipepart works with --header, --regexp, --cat and --fifo.
- ./configure --disable-documentation will not build documentation.
- {%} works as job slot.
- Bug fixes and man page updates.
20140522
- Use --semaphoretimeout to ignore the semaphore lock after a while.
- {%} introduced as job slot replacement string. It has known bugs.
- --slotreplace changes slot replacement string.
- Bug fixes and man page updates.
20140422
- --pipepart is a highly efficient alternative to --pipe if the input
is a real file and not a pipe.
- If using --cat or --fifo with --pipe the {} in the command will be
replaced with the name of a physical file and a fifo respectively
containing the block from --pipe. Useful for commands that cannot
read from standard input (stdin).
- --controlmaster has gotten an overhaul and is no longer
experimental.
- --env is now copied when determining CPUs on remote system. Useful
for copying $PATH if parallel is not in the normal path.
- --results now chops the argument if the argument is longer than the
allowed path length.
- Build now survives if pod2* are not installed.
- Bug fixes and man page updates.
20140322
- Bug fixes and man page updates.
20140222
- --tollef has been retired.
- --compress has be redesigned due to bugs.
- Format of --eta and --joblog has changed slightly.
- Bug fixes and man page updates.
20140122
- Bug fixes and man page updates.
20131222
- GNU Parallel now has a motto: For people who live life in the
parallel lane.
- Detect if the buffer dir $TMPDIR runs out of space. This changes a
central piece of code, making this release alpha quality.
- --keep-order --(n)onall will sort according to the sshlogin.
- Detect the number of CPUs on DEC Tru64.
- GNU sql: --list-tables for sqlite3.
- Bug fixes and man page updates.
20131122
- A citation notice is printed on stderr only if stderr is a terminal,
the user has not specified --no-notice and the user has not run
--bibtex once. This makes the release alpha quality.
- --compress will compress temporary files. If the output is big and
very compressible this will take up less disk space in $TMPDIR and
possibly be faster due to less disk I/O.
- --compress-program comtrols which program to use for compressing
temporary files.
- --bar show progress as a progress bar compatible with zenity.
- --resume can now be used with --result: Jobs already run will be
skipped.
- --transfer and --basefile support paths relative to the --workdir by
inserting /./ into the path.
- Bug fixes and man page updates.
20131022
- --transfer files with /./ in the path will copy the files relative
to the --workdir.
- The maximal command length is now cached in a file halfing the
startup time.
- Bug fixes and man page updates.
20130922
- PDF-files of documentation is now included.
- Bug fixes and man page updates.
20130822
- A tutorial showing much of GNU Parallel's functionality. Spend an
hour walking through the tutorial. Your commandline will love you
for it. man parallel_tutorial
- --line-buffer will buffer output on line basis. --group keeps the
output together for a whole job. --ungroup allows output to mixup
with half a line coming from one job and half a line coming from
another job. --line-buffer fits between these two; it prints a full
line, but will allow for mixing lines of different jobs.
- --record-env records all variables and functions set. Useful to
record the normal environment before using --env _.
- --env _ exports all functions and variables to the remote server
except for the ones recorded.
- New signing key. Due to recommendations from NIST
http://www.keylength.com/en/4/ the signing key was changed from
1024D/ID:FFFFFFF1 to 9888R/ID:88888888.
- Bug fixes and man page updates.
20130722
- --round-robin with --pipe will write all blocks to already running
jobs.
- --env can now transfer Bash function for remote execution. That is
pretty cool!
- Quite a few bug fixes and man page updates.
20130622
- --xapply now recycles arguments if an input source has more
arguments than others.
- The sleep time between jobs is now both increased and decreased
exponentially.
- 10 seconds installation check the signature using GnuPG if GnuPG is
installed.
- Bug fixes and man page updates.
20130522
- --ctrlc is now default if --pipe is not used; thus making it
possible to kill remotely started jobs simply by pressing Ctrl-C.
- --timeout 200% now means kill jobs that take more than twice the
time of the median run time of a job.
- Jobs are now distributed round robin when having mulitiple
--sshlogin instead of filling up one --sshlogin at a time.
- niceload: darwin version of --io --mem --swap. Thanks to Anders F
Bjorklund.
- Bug fixes and man page updates.
20130422
- 10 seconds installation: wget -O - pi.dk/3 | sh
- HPUX CPU/core detection. Thanks to Javier Tarradas.
- CPU detection for HURD, IRIX, SCO OpenServer and (old) HPUX.
- --ctrlc will send SIGINT to tasks running on remote computers and
thus killing them.
- --load now uses 'ps' to see immediately see the number of running
processes instead of 'uptime' thus making --load react much faster.
- Testing on Centos 3.9 and FreeBSD 7 revealed a lot of compability
bugs. Some of these required quite extensive changes making this
release beta quality.
- --retries works with --onall.
- The new --load computation now works on FreeBSD 7.
- --nice works under tcsh.
- Bug fixes and man page updates.
20130222
- --resume works with --pipe.
- --resume-failed will go through --joblog, redo the failed jobs and
then continue like --resume.
- Negative positional arguments count from the end: {-1} means the
last argument, {-2} the second to last.
- NetBSD CPU detection.
- --blocksize increases exponentially if it smaller than a full
record.
- Processing n-line records (--pipe -L n) is now much faster.
- --tollef is obsoleted after discussion on the mailing list.
- Bug fixes and man page updates.

** version numbering scheme. The v1.10.x release series is based on
** the v1.8.x series, but with a few new features. v2.x will be the
** next series after the v1.10.x series, and complete the transition
** to the new version numbering scheme. See README for more details
** on the new versioning scheme.

1.7.4
-----
**********************************************************************
* CRITICAL CHANGE
*
* As of release 1.7.4, OpenMPI's default mapping, ranking, and binding
* settings have changed:
*
* Mapping:
* if #procs <= 2, default to map-by core
* if #procs > 2, default to map-by socket
* Ranking:
* if default mapping is used, then default to rank-by slot
* if map-by <obj> is given, then default to rank-by <obj>,
* where <obj> is whatever object we mapped against
* Binding:
* default to bind-to core
*
* Users can override any of these settings individually using the
* corresponding MCA parameter. Note that multi-threaded applications
* in particular may want to override at least the binding default
* to allow threads to use multiple cores.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

pkgsrc changes: stop regenerating build system
and drop build-time dependency on autotools.

- Automatically scales graphical box width to the inner text in Cairo,
ASCII and Windows outputs.
- Add --rect to lstopo to force rectangular layout even for NUMA nodes.
- Add --restrict-flags to configure the behavior of --restrict.
- Objects may have a "Type" info attribute to specify a better type name
and display it in lstopo.
- Really export all verbose information to the given output file.
+ hwloc-annotate
- May now operate on all types of objects, including I/O.
- May now insert Misc objects in the topology.
- Do not drop instruction caches and I/O devices from the output anymore.

on some node, it should use HWLOC_MEMBIND_BIND.
Thanks to Nicolas Bouzat for reporting the issue.
+ Add a "Miscellaneous objects" section in the documentation.
+ Add a FAQ entry "What happens to my topology if I disable symmetric
multithreading, hyper-threading, etc. ?" to the documentation.
Version 1.10.1
--------------
* Actually remove disallowed NUMA nodes from nodesets when the whole-system
flag isn't enabled.
* Fix the gathering of PCI domains. Thanks to James Custer for reporting
the issue and providing a patch.
* Fix the merging of identical parent and child in presence of Misc objects.
Thanks to Dave Love for reporting the issue.
* Fix some misordering of children when merging with ignore_keep_structure()
in partially allowed topologies.
* Fix an overzealous assertion in the debug code when running on a single-PU
host with I/O. Thanks to Thomas Van Doren for reporting the issue.
* Don't forget to setup NUMA node object nodesets in x86 backend (for BSDs)
and OSF/Tru64 backend.
* Fix cpuid-x86 build error with gcc -O3 on x86-32. Thanks to Thomas Van Doren
for reporting the issue.
* Fix support for future very large caches in the x86 backend.
* Fix vendor/device names for SR-IOV PCI devices on Linux.
* Fix an unlikely crash in case of buggy hierarchical distance matrix.
* Fix PU os_index on some AIX releases. Thanks to Hendryk Bockelmann and
Erik Schnetter for helping debugging.
* Fix hwloc_bitmap_isincluded() in case of infinite sets.
* Change hwloc-ls.desktop into a lstopo.desktop and only install it if
lstopo is built with Cairo/X11 support. It cannot work with a non-graphical
lstopo or hwloc-ls.
* Add support for the renaming of Socket into Package in future releases.
* Add support for the replacement of HWLOC_OBJ_NODE with HWLOC_OBJ_NUMANODE
in future releases.
* Clarify the documentation of distance matrices in hwloc.h and in the manpage
of the hwloc-distances. Thanks to Dave Love for the suggestion.
* Improve some error messages by displaying more information about the
hwloc library in use.
* Document how to deal with the ABI break when upgrading to the upcoming 2.0
See "How do I handle ABI breaks and API upgrades ?" in the FAQ.
Version 1.10.0
--------------
* API
+ Add hwloc_topology_export_synthetic() to export a topology to a
synthetic string without using lstopo. See the Synthetic topologies
section in the documentation.
+ Add hwloc_topology_set/get_userdata() to let the application save
a private pointer in the topology whenever it needs a way to find
its own object corresponding to a topology.
+ Add hwloc_get_numanode_obj_by_os_index() and document that this function
as well as hwloc_get_pu_obj_by_os_index() are good at converting
nodesets and cpusets into objects.
+ hwloc_distrib() does not ignore any objects anymore when there are
too many of them. They get merged with others instead.
Thanks to Tim Creech for reporting the issue.
* Tools
+ hwloc-bind --get <command-line> now executes the command after displaying
the binding instead of ignoring the command entirely.
Thanks to John Donners for the suggestion.
+ Clarify that memory sizes shown in lstopo are local by default
unless specified (total memory added in the root object).
* Synthetic topologies
+ Synthetic topology descriptions may now specify attributes such as
memory sizes and OS indexes. See the Synthetic topologies section
in the documentation.
+ lstopo now exports in this fully-detailed format by default.
The new option --export-synthetic-flags may be used to revert
back the old format.
* Documentation
+ Add the doc/examples/ subdirectory with several real-life examples,
including the already existing hwloc-hello.C for basics.
Thanks to Rob Aulwes for the suggestion.
+ Improve the documentation of CPU and memory binding in the API.
+ Add a FAQ entry about operating system errors, especially on AMD
platforms with buggy cache information.
+ Add a FAQ entry about loading many topologies in a single program.
* Misc
+ Work around buggy Linux kernels reporting 2 sockets instead
1 socket with 2 NUMA nodes for each Xeon E5 v3 (Haswell) processor.
+ pciutils/libpci support is now removed since libpciaccess works
well and there's also a Linux-specific PCI backend. For the record,
pciutils was GPL and therefore disabled by default since v1.6.2.
+ Add --disable-cpuid configure flag to work around buggy processor
simulators reporting invalid CPUID information.
Thanks for Andrew Friedley for reporting the issue.
+ Fix a racy use of libltdl when manipulating multiple topologies in
different threads.
Thanks to Andra Hugo for reporting the issue and testing patches.
+ Fix some build failures in private/misc.h.
Thanks to Pavan Balaji and Ralph Castain for the reports.
+ Fix failures to detect X11/Xutil.h on some Solaris platforms.
Thanks to Siegmar Gross for reporting the failure.
+ The plugin ABI has changed, this release will not load plugins
built against previous hwloc releases.
Version 1.9.1
-------------
* Fix a crash when the PCI locality is invalid. Attach to the root object
instead. Thanks to Nicolas Denoyelle for reporting the issue.
* Fix -f in lstopo manpage. Thanks to Jirka Hladky for reporting the issue.
* Fix hwloc_obj_type_sscanf() and others when strncasecmp() is not properly
available. Thanks to Nick Papior Andersen for reporting the problem.
* Mark Linux file descriptors as close-on-exec to avoid leaks on exec.
* Fix some minor memory leaks.
Version 1.9.0
-------------
* API
+ Add hwloc_obj_type_sscanf() to extend hwloc_obj_type_of_string() with
type-specific attributes such as Cache/Group depth and Cache type.
hwloc_obj_type_of_string() is moved to hwloc/deprecated.h.
+ Add hwloc_linux_get_tid_last_cpu_location() for retrieving the
last CPU where a Linux thread given by TID ran.
+ Add hwloc_distrib() to extend the old hwloc_distribute[v]() functions.
hwloc_distribute[v]() is moved to hwloc/deprecated.h.
+ Don't mix total and local memory when displaying verbose object attributes
with hwloc_obj_attr_snprintf() or in lstopo.
* Backends
+ Add CPUVendor, CPUModelNumber and CPUFamilyNumber info attributes for
x86, ia64 and Xeon Phi sockets on Linux, to extend the x86-specific
support added in v1.8.1. Requested by Ralph Castain.
+ Add many CPU- and Platform-related info attributes on ARM and POWER
platforms, in the Machine and Socket objects.
+ Add CUDA info attributes describing the number of multiprocessors and
cores and the size of the global, shared and L2 cache memories in CUDA
OS devices.
+ Add OpenCL info attributes describing the number of compute units and
the global memory size in OpenCL OS devices.
+ The synthetic backend now accepts extended types such as L2Cache, L1i or
Group3. lstopo also exports synthetic strings using these extended types.
* Tools
+ lstopo
- Do not overwrite output files by default anymore.
Pass -f or --force to enforce it.
- Display OpenCL, CUDA and Xeon Phi numbers of cores and memory sizes
in the graphical output.
- Fix export to stdout when specifying a Cairo-based output type
with --of.
+ hwloc-ps
- Add -e or --get-last-cpu-location to report where processes/threads
run instead of where they are bound.
- Report locations as likely-more-useful objects such as Cores or Sockets
instead of Caches when possible.
+ hwloc-bind
- Fix failure on Windows when not using --pid.
- Add -e as a synonym to --get-last-cpu-location.
+ hwloc-distrib
- Add --reverse to distribute using last objects first and singlify
into last bits first. Thanks to Jirka Hladky for the suggestion.
+ hwloc-info
- Report unified caches when looking for data or instruction cache
ancestor objects.
* Misc
+ Add experimental Visual Studio support under contrib/windows.
Thanks to Eloi Gaudry for his help and for providing the first draft.
+ Fix some overzealous assertions and warnings about the ordering of
objects on a level with respect to cpusets. The ordering is only
guaranteed for complete cpusets (based on the first bit in sets).
+ Fix some memory leaks when importing xml diffs and when exporting a
"too complex" entry.
Version 1.8.1
-------------
* Fix the cpuid code on Windows 64bits so that the x86 backend gets
enabled as expected and can populate CPU information.
Thanks to Robin Scher for reporting the problem.
* Add CPUVendor/CPUModelNumber/CPUFamilyNumber attributes when running
on x86 architecture. Thanks to Ralph Castain for the suggestion.
* Work around buggy BIOS reporting duplicate NUMA nodes on Linux.
Thanks to Jeff Becker for reporting the problem and testing the patch.
* Add a name to the lstopo graphical window. Thanks to Michael Prokop
for reporting the issue.
Version 1.8.0
-------------
* New components
+ Add the "linuxpci" component that always works on Linux even when
libpciaccess and libpci aren't available (and even with a modified
file-system root). By default the old "pci" component runs first
because "linuxpci" lacks device names (obj->name is always NULL).
* API
+ Add the topology difference API in hwloc/diff.h for manipulating
many similar topologies.
+ Add hwloc_topology_dup() for duplicating an entire topology.
+ hwloc.h and hwloc/helper.h have been reorganized to clarify the
documentation sections. The actual inline code has moved out of hwloc.h
into the new hwloc/inlines.h.
+ Deprecated functions are now in hwloc/deprecated.h, and not in the
official documentation anymore.
* Tools
+ Add hwloc-diff and hwloc-patch tools together with the new diff API.
+ Add hwloc-compress-dir to (de)compress an entire directory of XML files
using hwloc-diff and hwloc-patch.
+ Object colors in the graphical output of lstopo may be changed by adding
a "lstopoStyle" info attribute. See CUSTOM COLORS in the lstopo(1) manpage
for details. Thanks to Jirka Hladky for discussing the idea.
+ hwloc-gather-topology may now gather I/O-related files on Linux when
--io is given. Only the linuxpci component supports discovering I/O
objects from these extended tarballs.
+ hwloc-annotate now supports --ri to remove/replace info attributes with
a given name.
+ hwloc-info supports "root" and "all" special locations for dumping
information about the root object.
+ lstopo now supports --append-legend to append custom lines of text
to the legend in the graphical output. Thanks to Jirka Hladky for
discussing the idea.
+ hwloc-calc and friends have a more robust parsing of locations given
on the command-line and they report useful error messages about it.
+ Add --whole-system to hwloc-bind, hwloc-calc, hwloc-distances and
hwloc-distrib, and add --restrict to hwloc-bind for uniformity among
tools.
* Misc
+ Calling hwloc_topology_load() or hwloc_topology_set_*() on an already
loaded topology now returns an error (deprecated since release 1.6.1).
+ Fix the initialisation of cpusets and nodesets in Group objects added
when inserting PCI hostbridges.
+ Never merge Group objects that were added explicitly by the user with
hwloc_custom_insert_group_object_by_parent().
+ Add a sanity check during dynamic plugin loading to prevent some
crashes when hwloc is dynamically loaded by another plugin mechanisms.
+ Add --with-hwloc-plugins-path to specify the install/load directories
of plugins.
+ Add the MICSerialNumber info attribute to the root object when running
hwloc inside a Xeon Phi to match the same attribute in the MIC OS device
when running in the host.
Version 1.7.2
-------------
* Do not create invalid block OS devices on very old Linux kernel such
as RHEL4 2.6.9.
* Fix PCI subvendor/device IDs.
* Fix the management of Misc objects inserted by parent.
Thanks to Jirka Hladky for reporting the problem.
* Add a Port<n>State into attribute to OpenFabrics OS devices.
* Add a MICSerialNumber info attribute to Xeon PHI/MIC OS devices.
* Improve verbose error messages when failing to load from XML.
