  • v0.3.3 Changes

    August 30, 2018

    common:

    • thread memory allocation has been switched back to the method
      👉 used before version 0.3.1       due to unexpected problems caused by
      the new code under some circumstances. A new compile-time option
      USE_TLS has been added to allow enabling the new code instead       ,
      0️⃣ and it is hoped that this can become the default again in the next version.
    • 🛠 LAPACK PR272 has been integrated, which fixes spurious errors
      in DSYEVR and related functions caused by missing conversion
      from ILAENV to ILAENV_2STAGE in several _2stage routines.
    • the cmake-generated OpenBLASConfig.cmake now uses correct case
      for the name of the library
    • ➕ added support for Haiku OS

    x86_64:

    • ➕ added AVX512 implementations of SDOT, DDOT, SAXPY, DAXPY,
      DSCAL, DGEMVN and DSYMVL
    • ➕ added a workaround for a cygwin issue that prevented compilation
      of AVX512 code

    IBM Z:

    • ➕ added autodetection of Z14
    • 🛠 fixed TRMM errors in the generic target

    common:

    • 🛠 fixes for regressions caused by the rewrite of the thread initialization code in 0.3.1

    x86_64:

    • ➕ added autodetection of AMD Ryzen 2
    • 🛠 fixed build with older versions of MSVC

    Power:

    • 🛠 fixed cpu autodetection for the BSDs

  • v0.3.1 Changes

    July 01, 2018

    common:

    • rewritten thread initialization code with significantly reduced overhead
    • ➕ added CBLAS interfaces to the IxAMIN BLAS extension functions
    • 🛠 fixed the lapack-test target
    • 🏗 CMAKE builds now create an OpenBLASConfig.cmake file
    • ZAXPY now uses a single thread for small input sizes
    • ⚡️ the LAPACK code was updated from Reference-LAPACK/lapack#253

    POWER:

    • corrected CROT and ZROT behaviour with zero INC_X

    ARMV7:

    • corrected xDOT behaviour with zero INC_X or INC_Y

    x86_64:

    • 🏗 retired some older targets of DYNAMIC_ARCH builds to a new option DYNAMIC_OLDER,
      this affects PENRYN,DUNNINGTON,OPTERON,OPTERON_SSE3,BOBCAT,ATOM and NANO
      👍 (which will still be supported via the slower PRESCOTT kernels when this option is not set)
    • added an option DYNAMIC_LIST that (used in conjunction with DYNAMIC_ARCH) allows
      👍 to specify the list of x86_64 targets to include. Any target not on the list will be supported by
      the Sandybridge or Nehalem kernels if available, or by Prescott.
    • 👌 improved SWITCH_RATIO on Haswell for increased GEMM throughput
    • ➕ added initial support for Intel Skylake X, including an AVX512 SGEMM kernel
    • ➕ added autodetection of Intel Cannon Lake series as Skylake X
    • ➕ added a default L2 cache size for hypervisors that return zero here (Chromebook)
    • 🛠 fixed a name clash with recent Windows10 headers that broke the build with (at least)
      recent mingw from MSYS2
    • 🛠 fixed a link error in mixed clang/gfortran builds with OpenMP
    • 🚀 updated the OSX deployment target to 10.8
    • 🏁 switched on parallel make for builds on MS Windows by default

    x86:

    • fixed SSWAP and DSWAP behaviour with zero INC_X and INC_Y
