      Fix name clash with reservered symbol 'mpi_status' · 67be7503
      Lorenz Huedepohl authored
      Apparently in some compiler/MPI combinations (gcc with impi 5.1.3) the
      identifier 'mpi_status' is defined and exporeted in their MPI fortran
      module and it is thus not allowed to name one of your local variables
      also 'mpi_status'.
      
      The confusing error message I got was
      
        ../src/elpa2_compute.F90:5780:37:
      
                        call mpi_wait(ireq_hv,mpi_status,mpierr)
                                             1
        Error: Invalid procedure argument at (1)
      
      even though everything seemed to be defined correctly

      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.

      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

      Optional build of ELPA without MPI · 49f119aa
      Andreas Marek authored
      The configure flag "--enable-shared-memory-only" triggers a build
      of ELPA without MPI support:
      
      - all MPI calls are skipped (or overloaded)
      - all calls to scalapack functions are replaced by the corresponding
        lapack calls
      - all calls to blacs are skipped
      
      Using ELPA without MPI gives the same results as using ELPA with 1 MPI
      task!
      
      This version is not yet optimized for performance, here and there some
      unecessary copies are done.
      
      Ths version is intended for users, who do not have MPI in their
      application but still would like to use ELPA on one compute node
