      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

      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_2013.11.006 bugfix for kernels real blocking 6 and 4 · f0c7cb0d
      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_2013.11.005 Changes in OpenMP detection · c4e3b88c
      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.

      Add parallel build functionality in ELPA_development_version_qr · 0cf41397
      Andreas Marek authored
      Automake does normally not understand the dependencies of Fortran 90
      modules, thus a parallel build will almost certainly fail.
      
      As in ELPA 2011.12.002, the ELPA_development_version_qr  now
      includes scripts from the fdep project (see git.schokokeks.org/fdep)
      which cirumvents this problem.
      
      Thanks to Lorenz Huedepohl, now a parallel build works.

      ELPA_2013.11 release (minor version 000) · ea970032
      Andreas Marek authored
      This is the release of the ELPA_development_version_OpenMP
      If OpenMP support is not used, this version has the same
      functionality as ELPA_2013.08.
      
      If OpenMP support is used, obviously, a hybrid version of ELPA will be
      build.
      
      Allthough this is a release, version ELPA_2013.11 is far from complete!
      During the next week optimizations of the OpenMP part will be published,
      however, the basic functionality is set by this commit

      Introducing OpenMP functionality in ELPA_development_version_OpenMP · 48e712ef
      Andreas Marek authored
      This commit introduces OpenMP functionality in the
      ELPA_development_version_OpenMP branch.
      
      It contains several bugfixes to the OpenMP functionality in the
      branch "ELPA_development_version", the later will soon be deleted
      since the new branch is the new reference implementation.
      
      The current branch contains the following features/bugfixes:
      - building of the OpenMP version of ELPA via configure and the
        "--with-openmp" flag. The build library contains a "_mt"
        (multi-threaded) in its name.
        The configure procedure should (hopefully) determine for each
        compiler the neccessary OpenMP flags.
        If the "--with-openmp" flag is ommitted exactly the same code
        as in the ELPA 2013.08.001 release is used and build in the
        same way
      - The example test cases print which kernels have been used and
        how many OpenMP threads are used at runtime
      - correct handling of OpenMP stack arrays: the previous implementation
        caused compiler dependent segmentation faults
      - OpenMP capability with all available kernels: the correctness of
        the computations have been checked for all kernels except the
        Bluegene (P/Q) versions

      Change of versioning of ELPA lib and the API · 411999c8
      Andreas Marek authored
      Thanks to a comment to the Debian community, the versioning
      of the ELPA library and its API are changed:
      
      - the API version nummer starts now with 0.0.0 and not
        anymore with the version number of the first ELPA release,
        i.e. 2011.12
      
      - if ELPA is installed as library, the files are now named
        elpa.so.API_VERSION. All references to the ELPA version
        and the used compiler vanished, since these are considered
        harmeful.
      
      Note, that at a later stage, if neccessary, the library name might
      also contain the uses MPI version.

      Automake feature for this ELPA version · 00116c53
      Andreas Marek authored
      Similiar to ELPA_2011.12 this version of ELPA now supports automake.
      
      To the _source_ code of ELPA the following changes had to be made:
      
      -elpa2.F90 now use the create "config-f90.h" file to choose via
       preprocessor switches which kernel was defined by the user
      
      - the SSE-AVX intrinsic kernels of A. Heinecke had to be changed such
        that they support "internal linkage" for the building of a shared
        library.
      
      The following other changes were made to the documentation
      
      - elpa2_kernels/README_elpa2_kernels.txt was updated; the new configure
        targets are explained
      
      - README, INSTALL were updated
      
      To high propability this commit is the last one, before this beta
      version	will become an official release
