      Man pages for ELPA · b1df09cd
      Andreas Marek authored
      For the library functions which are accessible by the user
      man pages decribing the Fortran and C interface exist:
      
      -get_elpa_row_comms
      -solve_evp_real , solve_evp_complex
      -solve_evp_real_2stage, solve_evp_complex_2stage
      
      For the "service binary" print_available_elpa2_kernels,
      also a man page exists.
      
      TODO: extend man pages to test-binaries, or do not install test-binaries

      Create doxygen documentation for ELPA · 927f988a
      Andreas Marek authored
      The user functions of ELPA are now documented with doxygen tags.
      At the moment the interface of ELPA 2015.11.001 is decribed.
      
      The documentation has step by step to be implemented for all functions
      and test programms.

      Split file elpa2.F90 into elpa2.F90 and elpa2_compute.F90 · 2998fac3
      Andreas Marek authored
      As in a previous commit for elpa1.F90, for automatic generation of
      documentation elpa2.F90 has been splitted in two files, in order to
      have a lean, easy-to-understand user interface:
      
      elpa2.F90
      the visible user functions, which provide the library calls.
      The usage is the same as before
      
      elpa2_compute.F90
      all internal routines, which are used by ELPA2, but which are never
      called external of the library by a user. These functions are now
      "hidden" in the module elpa2_compute, which is used by ELPA2.
      
      The procedures in elpa2_compute.F90 are identical to the ones in
      elpa2.F90 before this split commit. The only -- but quite a lot of them
      -- changes are intendation changes.

      first attempt to fix the bug which was rolled back in 402629d9. · b6ce5fd4
      Alexander Heinecke authored
      Current fix does as much blocking as possible, which should be
      beneficial from both a compute and communication point of view.
      
      Additionally, a second possible fix was added which just calls
      the blocked version if the local matrix has a sufficient size.
      This might create smaller and more messages at scale.

      Bugfix in ELPA_2015.11.001, roll back of minor changes · 402629d9
      Andreas Marek authored
      For some matrix/block size combinations the real case of ELPA2
      crashes, e.g:
      
      mpiexec -n 1 ./elpa2_test_real 50 50 32
      
      leads to an error message
       ** On entry to DGEMM parameter number  3 had an illegal value
       and a crash.
      
      This only seems to happen with matrix size smaller than 64*64.
      he code path responsible for this has been identified, but the problem
      tself is not yet solved!
      
      The part of the code, which causes these crashes, has been switched on
      as default by Intel in commit fe63372d. The rest of the commit fe63372d
      seems to be fine, and is performance critical.
      
      As an intermediate step, the responsible code path is switched off again
      as default, this will be changed again once the underlying root cause
      has been solved.

      The API versioning number was not updated correctly at the release.
      This lead to a wrong soname.

      Update of c test cases · 505004e7
      Andreas Marek authored
      The examples, how to invoke ELPA from a c program have been updated.
      There are now examples for ELPA1 and ELPA2 both real and complex case.
      The test cases are still with less functionality than their Fortran
      counter parts, they are just ment as a "proof-of-concept".
