      Release version of ELPA_2015.02 · 9aa39397
      Andreas Marek authored
      As obvious from the previous commits, this release of ELPA
      introduces a (optional) QR-decomposition for real valued
      matrices. This option can be used at run-time by either setting
      an environment variable, or by calling the ELPA-2 solver for
      real matrices with an additional flag.
      
      Thus the ABI changed, w.r.t. previous versions.
      
      Furthermore, the build process of ELPA has been made more
      consistent. All optimization flags (especially O1, O2 etc.)
      have to be set at build time by the user via the CFLAGS, FCFLAGS,
      and CXXFLAGS variables. The configure script does not set
      automatically the "O-Flags" anymore.

      Improve OpenMP detection in configure.ac · 254bd8ef
      Lorenz Huedepohl authored
      Some users where "clever" enough to supply a library in LDFLAGS/LIBS
      thath contained omp_get_num_threads, therefore tricking configure into
      thinking that we do not need any flags to enable OpenMP.
      
      Now the Fortran test only works if "use omp_lib" and "!$" OpenMP
      conditional compilation work.
      
      Also, if no valid OpenMP flag could be detected configure silently
      continued. I changed this to an explicit error.

      ELPA 2014.06.004 Optional usage of detailed timings · ae473b44
      Andreas Marek authored
      At build time it can be specified that the ELPA test
      programs give more detailed timing information, which
      is usefull for performace measurements

      ELPA 2014.06.003: Allow redirect of MPI task output · 7ddffdbd
      Andreas Marek authored
      If specified in the configure step, the test programs
      redirect their stdout and stderr output of each MPI
      task in a seperate file, which will be stored in a
      subdirectory "mpi_stdout".
      
      This will only be done if the environment variable
      "REDIRECT_ELPA_TEST_OUTPUT" is set to "true"

      fdep fixes for procedures, compilation errors · dc8b1090

      Train fdep to recognize
      
        module procedure ...
      
      lines. Also, previoulsy an fdep internal error aborted make, however the
      partially generated dependency file stayed and was used in that form on
      a subsequent make call.

      Fix for fdep to avoid warnings · c46b07b5
      Lorenz Huedepohl authored
      Multiple rules for the same dummy-file were created for modules used by
      sources of more than one program. Corrected by including the program
      name into the dummy-files

      Another ABI change in ELPA_2014.06 pre-release · a2b2e6bf
      Andreas Marek authored
      Build servers recommend against calling "abort" functions in a
      library. Thus, from now on, ELPA  returns a success flag, which
      is a change of ABI!
      
      In order to force the user to honour this, the ELPA drivers
      are converted to functions, which implies an adaptation and
      rebuild of the user code. The driver functions return a
      logical "success", which, if it is false, indicates an
      error within the library.
      
      It is advised to check catch and check this
      return value in the user code, which calls ELPA.
