      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.

      Removed a forgotten C-preprocessor error flag.
      Futhermore, describe in the documentation why at the moment a
      build of Bluegene P/Q kernels and OpenMP is not allowed.

      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

      This commit releases ELPA version 2013.08
      
      It is identical with the latest commit version 2013.02_BETA, except:
      
      - rename ELPA_2013.02.BETA -> ELPA_2013.08
      - update of configure.ac
      - remove of src/elpa2.f90_save
      - remove of test/Makefile
      
      This version has been tested extensivly, however, there might always
      be some bugs.
      In case of questions please contact elpa-library@rzg.mpg.de or via
      the ELPA forum on http://elpa-lib.fhi-berlin.mpg.de/forum/index.php

      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

      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
