      Make ELPA ready for packaging as RPM · 7ea5c43a
      Lorenz Huedepohl authored
      This includes a number of changes:
      
      - ScaLAPACK2 on from the openSUSE:science repository is now correctly
        auto-detected. As ScaLAPACK2 already includes BLACS, an additional
        BLACS library must not be linked!
      
      - The resulting library is now called elpa-2014.06.000.so, as was
        probably originally intended anyway
      
      - The pkg-config file was renamed to elpa-2014.06.000.pc and filled with
        correct values. With this, a package using ELPA can easily get the
        necessary compilation and library flags.
      
      In this commit, only the "precious" files (Makefile.am, configure.ac,
      etc.) are included, to make clear what has been changed by hand.
      
      In the subsequent commit also all autoconf generated files will follow.

      ELPA_2014.06 prepare release · 53f2f2c6
      Andreas Marek authored
      Now it is possible
      - to choose the kernel (real and complex independently) at run-time
        via environment variables, or
      - to specify the kernel (real and complex independently) at runtime
        via specifing the kernel in the call to ELPA
      
      This has a few implications
      1) The ELPA 2014.06 release has a change in the API and is thus not
         binary compatible with previous versions
      2) if no kernels are specified, a default kernel is choosen
      3) if a wrong kernel is specified, a default kernel is choosen
      
      For sake of simplicity it is still possible to build ELPA with
      support for only one kernel, as in previous versions. However, it is
      still not binary compatible to previous versions

      Prepare 2014.06.000: check for Fortran environment · c090a89f
      Andreas Marek authored
      Configure checks whether the Fortran environment module
      is available. If yes, the library is build such, that all
      messages (from within the library) are printed at the correct
      stderr unit. If not, then the stderr unit is set to unit=6

      Cleanup of configure.ac ELPA_2013.11; Create ELPA_2014.06 · b3d47d1e
      Andreas Marek authored
      The configure.ac of ELPA_2013.11 is cleaned up a bit
      Also, ELPA_2013.11 is copied to ELPA_2014.06 in order to have
      the base for the next ELPA release

      ELPA_development_version_qr: bugfix for kernels real blocking 6 and 4 · be241bd8
      Andreas Marek authored
      Due to an error in a preprocessor statement, the results for
      real matrices were wrong if the kernels "avx-real-block6" or
      "avx-real-block4" were chosen. No other kernels are affected.
      
      The test programms always correctly stated that the results for
      these kernels are wrong.

      ELPA_development_version_qr: Changes in OpenMP detection · 94020ebc
      Andreas Marek authored
      The Intel Fortran compiler accepts the flag "-fopenmp" for compilation
      with OpenMP. However, the Intel MPI compiler wrapper does not.
      With the Intel compiler, this leads to the fact, that if ELPA is compiled
      with the "-fopenmp" flag a not thread-save version of the Intel MPI
      library is used and the test (with make check) fails.
      
      Intel promised to solve this in the future.
      
      However, for now the problem is solved in the user friendly way that no
      manipulation of the MPI compiler wrappers have to be done:
      
      For detecting the OpenMP compiler flags, instead of the predefined
      macro "AC_OPENMP" of autoconf a modified macro "AX_ELPA_OPENMP"
      is used, which first checks "-openmp" and only then "-fopenmp".
      Thus it is ensured that the Intel compiler (and mpi compiler wrapper)
      does not get confused.
      
      This is invisible for users calling "configure" during the installation
      process.

      ELPA_development_version_qr: OpenMP tests return error code · b34a5a9c
      Andreas Marek authored
      If the ELPA library is compiled with OpenMP, the tests check
      whether the MPI library provides the neccessary threading
      level.
      
      There has been the error, that if the required threading level
      was not available the test programs aborted, put no explicit
      error code was set. This is changed now.
