Uses fork/wait so integrands do not have + to be reentrant. + + Specify number of cores in environment variable CUBACORES. + C/C++/Fortran only, Mathematica users need to replace MapSample + by ParallelMap or similar (as before). + + +18 Jun 11: + +- Fixed problem with inner integration bounds depending on outer + ones in the MathLink executables. + + +15 Feb 11: + +- Moved partview to Qt 4. + +- Rectified error reporting via longjmp, in particular avoiding + sending $Failed twice in MathLink which would upset the + following communications. + + +13 Sep 10: + +- Added iteration number to integrand's optional parameters + (Vegas and Suave). + +- Fixed initialization problem when using state file in Vegas. + +- Added tests for MathLink to configure. + + +20 Jul 10: + +- Fixed severe bug in divonne/Split.c (wrong sign in SignedDelta + macro). + + +14 Jul 10: + +- Disabled optimization for gcc 4.2.x and 4.4.3, which would lead + to an Internal Compiler Error when compiling Cuba, see + http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40237 + http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42956 + + +21 Jun 10: + +- Fixed problem with bashy syntax in tools/mcc. + + +8 Jun 10: + +- All Cuba functions now reentrant, except for gridptr_ and griddim_ + in Vegas, which are intentionally preserved across calls. + + +19 May 10: + +- Version 2.0: Changed invocations. + +- Added void *userdata to be passed to integrator. + +- Promoted integrand to int function, has to return 0 if successful, + otherwise integrator terminates immediately. + +- Moved all global variables (common blocks) to argument list. + + +12 Feb 10: + +- Added Ranlux pseudo-random number generator. + Luxury level 0 (mis)used for Mersenne Twister branch + (but observe that Luxury level 24 = Luxury level 0). + +- Changed external variable mersenneseed to + struct { unsigned int level, seed; } cubarandom; + + +22 Jul 09: + +- Fixed potential segfault in Split.c of Divonne, thanks to + Andreas v. Manteuffel. + + +29 May 09: + +- Added flushing of grids in Vegas through a negative grid number. + + +25 May 09: + +- Removed explicit pointer reference from reallocatable + "region_" array. + + +8 May 09: + +- Improved memory handling in Divonne. + + +8 Apr 09: + +- Version 1.6: Improved memory handling in Cuhre. + Thanks to Valery Yundin for pointing out the problem. + + +6 Mar 09: + +- Fixed segfault in Divonne if all samples from a region returned NaN. + +- Reinstated fcc to fix static linkage problem with mcc 7. + + +10 Feb 09: + +- Removed dependence on fcc script. + + +19 Jan 09: + +- Added missing #include <stdlib.h> to partview.cpp. + + +15 Jan 09: + +- Fixed problem with MathLink compilation for Mathematica 7. + + +5 Dec 08 + +- Version 1.5: Added possibility to set Mersenne Twister + random seed. + +- Introduced function MapSample to map the integrand over + the points, whose default value Map can be replaced e.g. + by ParallelMap. + + +15 Feb 08 + +- Added further check to Suave for sharp-edged functions. + + +15 Jan 08 + +- Fixed bug in makefile.in w.r.t. DESTDIR. + + +2 Jan 08 + +- Fixed minor bug in invocation of IniRandom in Suave. + + +19 Dec 07 + +- Version 1.4: Added new flag (bit 4), to turn off smoothing of + the importance function for sharp-edged functions. + +- Improved configure for Cygwin. Now compiles MathLink + executables `out of the box'. + + +30 Nov 07 + +- Fixed detection of variable-size arrays in configure.ac. + +- Minor fixes for autoconf 2.60. + + +30 Aug 07 + +- Added passing of weight information to the integrand routine + in Vegas and Suave. Mathematica versions use $Weight. + + +7 Mar 07 + +- Documented the ll versions in the manual. + + +1 Mar 06 + +- Version 1.3: added long long int versions, i.e. all + number-of-points-like quantities are now long long int + instead of int. The corresponding names are prefixed with + "ll", e.g. llVegas. + + +5 Jan 06 + +- Corrected a number of declarations so that changing the "number" + typedef in stddecl.h to a longer integer should work now. + Note that this bugfix has NO EFFECT if the "number" typedef + was not changed by hand! + + +31 Aug 05 + +- A small patch considerably reduces the "mysterious" problem + in Vegas and Suave that further iterations on a more or less + optimal grid would often degrade the grid. + + +2 Jun 05 + +- Added some #ifdefs to make the compile completely silent. + +- Changed HUGE_VAL to DBL_MAX to avoid problems with icc. + + +7 Mar 05 + +- Extended Divonne's Korobov tables. + +- partview now sorts the list of rectangles so that the smallest + ones come on top. + + +2 Mar 05 + +- Fixed "mysterious" problem where Divonne would report a + larger-than-requested error even though enough samples were + available. + + +17 Feb 05 + +- Rewrote partview.cpp with tabbed window. + +- Moved sources to src/{vegas,suave,divonne,cuhre}. + The original names would get into the way of the Mathematica + executables on OSX's case-insensitive file system. + + +15 Feb 05 + +- configure now disables compilation of demo-fortran if no + Fortran compiler is found. + + +9 Feb 05 + +- Added some explicit typecasts and other tidbits such that + Cuba compiles successfully also with a C++ compiler now. + + +7 Feb 05 + +- Added erf implementation in case some "C99 compliant" compiler + like M$ Visual C++ in fact has no erf. + + +4 Feb 05 + +- Added partview.m for Mathematica. + + +3 Feb 05 + +- Added proper autoconf configure. + +- Added cuba.F, a Fortran chooser which makes the invocation + of the Cuba routines still simpler from Fortran. + +- Straightened out the contexts of the MathLink executables. + + +2 Feb 05 + +- Substituted preprocessor variable NBATCH by run-time configurable + global variable vegasbatch_. + +- Added checks on ncomp. + + +1 Feb 05 + +- Added a partition viewer which displays the tesselation of the + integration region on screen. Needs Qt. + + +27 Jan 05 + +- Added a preprocessor flag NO_LONG_DOUBLE to disable the use + of long doubles on systems that don't have it. + + +25 Jan 05 + +- Rearranged Vegas to sample in batches of NBATCH points to + reduce memory consumption. + + +21 Jan 05 + +- Fixed bug in Divonne: Final result was wrong if not enough + samples left for Phase 3. + + +19 Jan 05 + +- Updated manual re pseudo-random sampling. + + +17 Jan 05 + +- Introduced "number" typedef, might be useful when using wide ints. + Not well tested, though. + +- Substituted [sd]rand48 by Mersenne Twister generator. + + +14 Jan 05 + +- Added pseudo-rng (bit 3 in flags). + +- Collected common declarations in stddecl.h. + +- Better checking of dimension (e.g. in Divonne, all cases). + + +12 Jan 05 + +- Updated manual re vegas{grid,state}. + + +23 Dec 04 + +- Fixed a memory leak in Cuhre. + + +18 Nov 04 + +- Added vegasstate load/restore of internal state. + + +16 Jul 04 + +- Added vegasgrid. + |
