      Additional configure check for gcc SSE intrinsics · 896388e9
      Andreas Marek authored
      It turned out that if a CPU supports SSE the already existing
      test for SSE assembly instructions always passes.
      However, the compilation of gcc SSE intrinic instructions might
      nevertheless fail if gcc is not called with one of the options
      "-msse3", "-msse4" , "-msse4.1", "-msse4.2", "-mavx", or "-mavx2"!
      
      Obviously gcc does still not consider SSE as a standard on X86_64
      Intel CPUs.
      
      An additional configure test has been introduced, which test for
      gcc intrinsic sse instructions. If this test fails, the corresponding
      kernels are switched off.

      AVX kernels need aligned memory · 59e405e0
      Lorenz Hüdepohl authored
      For the Intel compiler, this was assured with the pragma
      
        !DEC$ ATTRIBUTES ALIGN: 64:: a
      
      however, other compilers such as gcc of course did not honour this,
      which could result in SIGSEGVs in case the variable was not aligned to
      32 bytes (by chance!).
      
      This fixes issue #11, thanks to Nico Holmberg for reporting this.

      Introduction of new SSE kernels with different blocking · 69792b15
      Andreas Marek authored
      The SSE kernels with blocking of 2,4,6 (real case) and 1,2 (complex)
      case are now available by default
      
      Thus the following changes have been done
      - introduce new macros in configure.ac and Makefile.am
      - renmae the AVX kernels in AVX_AVX2 (they also support AVX2)
      - introduce new files with SSE kernel
      - introduce new kernel parameters !
      - make the SSE kernels callable
      
      The results are identical with previous kernels

      Allow ELPA to be build with single and double precision symbols in one · 647aa5a8
      Andreas Marek authored
      library
      
      It the configure option "--enable-single-precision" is specified,
      ELPA will also be build for single precision usage. The double precision
      and single precision will be available at the same time with names
      "solve_evp_real_1stage_double" or "solve_evp_real_1stage_single" and
      so on...
      
      This change immplied some major refactoring of the ELPA code:
      1.) functions/procedures had to be renamed with suffix "_double"
      
      2.) If necessary the same functions have to be available with suffix
      "_single"
      
      3.) Variable kind definitions have to be consistent with the
      intented use
      
      To avoid uneccessary code duplication this is done (most of the time)
      with preprocessor string substitution.
      
      The documentation has been updated.
      
      NOT SUPPORTED are at the moment:
      
      - single precision usage of ELPA2 with kernels, others than "generic"
        and "generic_simple"
      
      - single precision usage of GPU
