      configure.ac: move ELPA specific macros into ./m4 · c788ec6b
      Andreas Marek authored
      The macros which define the functionality to test
       - GPU support only (no CPU based kernels)
       - a specific real/complex kernel (not all available kernels)
      are now defined in files in the m4 directory

      configure.ac: treat GPU kernel as other kernels · 0a27d7c8
      Andreas Marek authored
      Configure treats the GPU kernels now as any other kernel, i. e.
      if GPU support is enabled (and it is possible to build it) then
      it will be build in ADDITION to all other possible kernels for
      the desired hardware.
      Also, it is possbile to configure the build process for
      the GPU version ONLY (as it was already possible to trigger the
      build for only ONE specific real/complex kernel).
      Note: The sources at the moment CANNOT handle this, i.e. if
      GPU support is configured, the GPU only code path is compiled.
      This will be changed in the near future.

      Handle different OpenMP flags for Fortran and C · ba9a188f
      Lorenz Huedepohl authored
      There was an inconsistency when the OpenMP flag was different for the
      Fortran and C compiler (e.g. -openmp for ifort and -fopenmp for gcc).
      This led to strange errors when linking the example program with the C
      main() routine when using Intel Fortran, Intel MPI, and GCC together, a
      typical error message was
        /usr/bin/ld: MPIR_Thread: TLS definition in [...]/intel64/lib/libmpi_dbg_mt.so section .tbss mismatches non-TLS definition in [...]/intel64/lib/libmpi_dbg.so section .bss
        [...]/intel64/lib/libmpi_dbg_mt.so: could not read symbols: Bad value
      The reason seems to be that the various MPI wrapper shell scripts
      (mpicc, mpiifort) need the correct OpenMP option to select the
      thread-safe Intel MPI debug library. Previously, always OPENMP_FCFLAGS
      was appended to LDFLAGS, which did not trigger this when linking a C
      main program with mpicc.

      If the user chooeses parameters for the QR-decomposition which are
      not allowed an error has been produced. This error is caught now,
      and the library aborts with a message
      It is now possible to switch on more debug messages via
      the environment variable "ELPA_DEBUG_MESSAGES=yes"

      Abort on error in QR-decomposition · ff13970b
      Andreas Marek authored
      If the QR-decomposition is used wrongly (matrix size is not a
      multiple of block size) the the execution will abort, in
      order to prevent the wrong results, discussed in a previous commit
      Debug messages are now available by setting the environment variable
      "ELPA_DEBUG_MESSAGES" to "yes".
