OpenBLAS ChangeLog
|
||||
====================================================================
|
||||
Version 0.3.8
|
||||
9-Feb-2020
|
||||
|
||||
common:
|
||||
` * LAPACK has been updated to 3.9.0 (plus patches up to
|
||||
January 2nd, 2020)
|
||||
* CMAKE support has been improved in several areas including
|
||||
cross-compilation
|
||||
* a thread race condition in the GEMM3M kernels was resolved
|
||||
* the "generic" (plain C) gemm beta kernel used by many targets
|
||||
has been sped up
|
||||
* an optimized version of the LAPACK trtrs functions has been added
|
||||
* an incompatibilty between the LAPACK tests and the OpenBLAS
|
||||
implementation of XERBLA was resolved, removing the numerous
|
||||
warnings about wrong error exits in the former
|
||||
* support for NetBSD has been added
|
||||
* support for compilation with g95 and non-GNU versions of ld
|
||||
has been improved
|
||||
* support for compilation with (upcoming) gcc 10 has been added
|
||||
|
||||
POWER:
|
||||
* worked around miscompilation of several POWER8 and POWER9
|
||||
kernels by older versions of gcc
|
||||
* added support for big-endian POWER8 and for compilation on AIX
|
||||
* corrected bugs in the big-endian support for PPC440 and PPC970
|
||||
* DYNAMIC_ARCH support is now available in CMAKE builds as well
|
||||
|
||||
ARMV8:
|
||||
* performance of DGEMM_BETA and SGEMM_NCOPY has been improved
|
||||
* compilation for 32bit works again
|
||||
* performance of the RPCC function has been improved
|
||||
* improved performance on small systems
|
||||
* DYNAMIC_ARCH support is now available in CMAKE builds as well
|
||||
* cross-compilation from OSX to IOS was simplified
|
||||
|
||||
x86_64:
|
||||
* a new AVX512 DGEMM kernel was added and the AVX512 SGEMM kernel
|
||||
was significantly improved
|
||||
* optimized AVX512 kernels for CGEMM and ZGEMM have been added
|
||||
* AVX2 kernels for STRMM, SGEMM, and CGEMM have been significantly
|
||||
sped up and optimized CGEMM3M and ZGEMM3M kernels have been added
|
||||
* added support for QEMU virtual cpus
|
||||
* a compilation problem with PGI and SUN compilers was fixed
|
||||
* Intel "Goldmont plus" is now autodetected
|
||||
* a potential crash on program exit on MS Windows has been fixed
|
||||
|
||||
x86:
|
||||
* an unwanted case sensitivity in the implementation of LSAME
|
||||
on older 32bit AMD cpus was fixed
|
||||
|
||||
zarch:
|
||||
* Z15 is now supported as Z14
|
||||
* DYNAMIC_ARCH is now available on ZARCH as well
|
||||
|
||||
====================================================================
|
||||
Version 0.3.7
|
||||
11-Aug 2019
|
||||
|
||||
common:
|
||||
* having the gmake special variables TARGET_ARCH or TARGET_MACH
|
||||
defined no longer causes build failures in ctest or utest
|
||||
* defining NO_AFFINITY or USE_TLS to 0 in gmake builds no longer
|
||||
has the same effect as setting them to 1
|
||||
* a new test program was added to allow checking the library for
|
||||
thread safety
|
||||
* a new option USE_LOCKING was added to ensure thread safety when
|
||||
OpenBLAS itself is built without multithreading but will be
|
||||
called from multiple threads.
|
||||
* a build failure on Linux with glibc versions earlier than 2.5
|
||||
was fixed
|
||||
* a runtime error with CPU enumeration (and NO_AFFINITY not set)
|
||||
on glibc 2.6 was fixed
|
||||
* NO_AFFINITY was added to the CMAKE options (and defaults to being
|
||||
active on Linux, as in the gmake builds)
|
||||
* having the gmake special variables TARGET_ARCH or TARGET_MACH
|
||||
defined no longer causes build failures in ctest or utest
|
||||
* defining NO_AFFINITY or USE_TLS to 0 in gmake builds no longer
|
||||

||||

|
||||
active on Linux, as in the gmake builds)
|
||||
|
||||
x86_64:
|
||||
* the build-time logic for detection of AVX512 availability in
|
||||
the processor and compiler was fixed
|
||||
* gmake builds on OSX now set the internal name of the library to
|
||||
libopenblas.0.dylib (consistent with CMAKE)
|
||||
* the Haswell DGEMM kernel received a significant speedup through
|
||||
improved prefetch and load instructions
|
||||
* performance of DGEMM, DTRMM, DTRSM and ZDOT on Zen/Zen2 was markedly
|
||||
increased by avoiding vpermpd instructions
|
||||
* the SKYLAKEX (AVX512) DGEMM helper functions have now been disabled
|
||||
to fix remaining errors in DGEMM, DSYMM and DTRMM

||||

|
||||
|
||||
## POWER:
|
||||
* added support for building on FreeBSD/powerpc64 and FreeBSD/ppc970
|
||||
* added optimized kernels for POWER9 SGEMM and STRMM

## ARMV7:
|
||||
* fixed the softfp implementations of xAMAX and IxAMAX
|
||||
* removed the predefined -march= flags on both ARMV5 and ARMV6 as
|
||||
they were appropriate for only a subset of platforms
