      integration of C implementation of Cannon algorithm to ELPA · 3eb37776
      Pavel Kus authored
      this commit does not work, the generalized EVP problems fail from 2
      reasons:
      - Cannons algorithm does not work for the processor grid shape we use at
        the moment in tests (It only works if num. of process columns is a
        multiple of num. of process rows, which is not true in ELPA for 2 mpi
        tasks)
      - Cannons algorithm does not work as integrated to ELPA for larger
        matrices (not clear why at the moment)
      
      There are 2 new tests, which should work
      - test_cannon.c: it tests the new algorithm without going through
        Fortran, as it has been delivered
      - test_c_bindings: it tests transfering a 2D fortran matrix to C and
        back, as it is done with the cannons algorithm in the normal ELPA
        tests

      Had to move some functions to the public namespace · 38335f50
      Lorenz Huedepohl authored
      The PGI compiler (of course) complained about a missing module
      (elpa_generated_fortran_interfaces.mod) when compiling the test
      programs.
      
      It is true (in a way) that some part of this module is indeed necessary,
      as the public-facing function signatures have arguments that are
      referring to those three functions in their type:
      
        elpa_strerr_c(elpa_error)
        elpa_int_value_to_string_c(name, value, string)
        elpa_int_value_to_strlen_c(name, value)
      
      Thus, for these three we create another header prefix,
      
        !pf>
      
      for Fortran definitions that should be public. Those are included in
      elpa_api.F90.
