      - updated INSTALL documentation
      - improved description of kernels src/elpa2_kernels/README_elpa2_kernels.txt
      - improved OpenMP builds:
         * usage of OpenMP can now be specified with
           "--enable-openmp" or "--with-openmp"
      - improved checks for AVX build (identical to ELPA 2013.08.003):
         * if AVX kernels are specified AVX compilation is tested
         * the option "--with-avx-optimization" automatically updates
           CFLAGS and CXXFLAGS with optimization flags

       - The INSTALL documentation was updated a bit
       - the documentation of the ELPA kernels was improved
       - the configure script was improved:
         if usage of an AVX kernel is specified, at configure time
         it is checked whether such a kernel can be build
         If not, it is checked whether the kernel can be build if the
         option "-mavx" is added to the CFLAGS and CXXFLAGS. If this is
         still not possible an error is thrown.
         if the option "--with-avx-optimization" than the CFLAGS and CXXFLAGS
         are automatically updated with some necessary flags (which are
         described in the kernel documentation file)

      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
      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

      Debug output of test cases · 50a000db
      Andreas Marek authored
      For debugging purposes the test examples of the ELPA library can
      now write the Eigenvectors in an ascii file, e.g
      a call of "test_real 4000 1500 16 output" will envoke the test
      case for real matrices of the ELPA1 library. A matrix of 4000x4000
      values will be created an 1500 EV's will be computet with a 16 blocking.
      And the results will be --- due to the output flag --- written to a
      text file

      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".

      Update of Install documentation · 82eaba06
      Andreas Marek authored
      It is pointed out that it is mandatory to set the variables
      "BLACS_LDFLAGS" and "BLACS_FCFLAGS" at build time.
      Furthermore, it is clarified how to set individual optimization
      flags at build time

      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
      Note, that at a later stage, if neccessary, the library name might
      also contain the uses MPI version.

      Automake build feature for ELPA_2011.12 · 5306eaa1
      Andreas Marek authored
      ELPA version 2011.12 can now be build with automake into
      a shared/static library. This should help the bundling in
      linux distributions
      The other versions of ELPA will be updated soon

      Tar archives of ELPA · c959495d
      Andreas Marek authored
      In addition to the "normal" ELPA git directories, I created
      a directory tar-archives.
      In this directory one should put tar-balls of the different versions
      of the ELPA library.
      Since the tar-balls "loose" the git history and are only a snapshot
      of the respective version at the time of creation, one should name
      the tar balls accordingly.
      I opted now for the naming of
      ELPA_VERSION_day_month_year_of_creation.tar.gz, e.g with the commit
      from today (17/06/2013) I created from the ELPA_VERSION "ELPA_2011.12"
      a tar ball named "ELPA_2011.12_17062013.tar.gz".
