      QR decompostion functionality in branch ELPA_development_version_qr · 52cda2cf
      Andreas Marek authored
      Now, the branch ELPA_development_version_qr contains the full QR
      functionality, which was introduced by Auckenthaler in the (obsolete)
      ELPA_development_version_branch
      
      Changes are:
      - build procedure with configure like the other branches/releases
      - renaming of a few files
      
      The QR decomposition was tested for a few matrices and gave correct
      results

      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

      BUGFIX and BUGFIX versioning · 9e3319b3
      Andreas Marek authored
      A bug in ELPA_2013.08 was fixed: due to typo in a preprocessor statement
      the kernels optimized for BLUGENE/P could not be used correctly.
      
      In course of this action, also a bugfix versioning scheme was
      introduced: in case of bugfixes they are versioned with an extra 3 digit
      number in the ELPA release name, i.e ELPA 2013.08 -> 2013.08.001
      
      Consistently any new release of ELPA will from now on start on the minor
      level "000".

      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
