      ELPA_2013.11 OpenMP tests return error code · 3d9c053b
      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.

      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

      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

      - remove of test/Makefile
      
      This version has been tested extensivly, however, there might always
      be some bugs.

      License cleanup · 6f563aff
      Andreas Marek authored
      On behalf of the Elpa Consortium and due to a remark of
      Volker Blum the license model of ELPA is "corrected"
      
      - each file now contains the appropiate header
      - the files in the subdirectory "COPYING" are now
        in accordance with LGPL v. 3, the license we choose
        to use

      We have taken the unusual (one-time) step to modify the structure
      of the ELPA git repository as follows:
      
      1) The current ELPA version has been designated as a "stable"
         version. It has proven to be rock solid for us so far, and
         deserves this name.
      
      2) We have decided on a stable version naming scheme,
         "ELPA_year.month". The first such version is
         ELPA_2011.12. This version will only ever be updated
         for clear and unambiguous bug fixes.
      
      3) All further development will happen in the directory named
         ELPA_development_version. At this time, ELPA_2011.12 is an
         exact copy of ELPA_development_version.
      
      No substantial changes have been made to either repository as yet.
      (But we are happy to say that the present "ELPA" publication, which
      we hope ELPA users will cite, now has its final volume and page
      numbers.)
      
      We apologize if this change causes any inconvenience for you. Please
      try to make sure that any changes you might make really affect the
      development version, and not the stable version. We do not plan any
      structural changes of a similar scope at any point in the future,
      but it had to be done once.
      
      Happy ELPA stable version day!
