      Optional build of ELPA without MPI · 49f119aa
      Andreas Marek authored
      The configure flag "--enable-shared-memory-only" triggers a build
      of ELPA without MPI support:
      
      - all MPI calls are skipped (or overloaded)
      - all calls to scalapack functions are replaced by the corresponding
        lapack calls
      - all calls to blacs are skipped
      
      Using ELPA without MPI gives the same results as using ELPA with 1 MPI
      task!
      
      This version is not yet optimized for performance, here and there some
      unecessary copies are done.
      
      Ths version is intended for users, who do not have MPI in their
      application but still would like to use ELPA on one compute node

      Started to remove depecrated Fortran variable declerations · 0a05f7d3
      Andreas Marek authored
      The Fortran variable declerations "variable type*[4,8,16]" is non
      Fortran standard. It might cause problem in the future.
      Furthermore, the usage of Fortran and C togehther is more clean
      if variables are defined according to C variable types.
      
      This is done, now for all the test programs

      Add interface to unify C and Fortran names · bb046d1c
      Andreas Marek authored
      This commit does not change the interfaces defined in ELPA_2015.11.001 !
      All functionality is available via the interface names and definitions
      as in ELPA_2015.11.001
      
      But some new interfaces have been added, in order to unfiy the
      references from C and Fortran codes:
      
      - The procedures to create the ELPA (row/column) communicators are now
        available from C _and_ Fortran with the name "get_elpa_communicators".
        The old Fortran name "get_elpa_row_col_comms" and the old C name
        "elpa_get_communicators" are from now on deprecated but still available
      
      - The 1-stage solver routines are available from C _and_ Fortran via
        the names "solve_evp_real_1stage" and "solve_evp_complex_1stage".
        The old Fortran names "solve_evp_real" and "solve_evp_complex" are
        from now on deprecated but still functional.
      
      All documentation (man pages, doxygen, and example test programs) have
      been changed accordingly.
      
      This commit implies a change in the API versioning number, but no
      changes to codes calling ELPA (if they have been already updated to the
      API of ELPA_2015.11.001)

      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".

      Change of get_elpa_row_col_comms to a function · fc80ad07
      Andreas Marek authored
      The procedure "get_elpa_row_col_comms" is now a function instead
      a subroutine and returns an error code.
      
      This should have been done previously when all the other ELPA
      function have been updated to return an error code.
      
      This requires an ABI change in the next ELPA release !

      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

      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.

      ELPA_2014.06 prepare release · 53f2f2c6
      Andreas Marek authored
      Now it is possible
      - to choose the kernel (real and complex independently) at run-time
        via environment variables, or
      - to specify the kernel (real and complex independently) at runtime
        via specifing the kernel in the call to ELPA
      
      This has a few implications
      1) The ELPA 2014.06 release has a change in the API and is thus not
         binary compatible with previous versions
      2) if no kernels are specified, a default kernel is choosen
      3) if a wrong kernel is specified, a default kernel is choosen
      
      For sake of simplicity it is still possible to build ELPA with
      support for only one kernel, as in previous versions. However, it is
      still not binary compatible to previous versions

      ELPA_2013.11 OpenMP tests return error code · 3d9c053b
      Andreas Marek authored
      If the ELPA library is compiled with OpenMP, the tests check
      whether the MPI library provides the neccessary threading level.
      
      There has been the error, that if the required threading level
      was not available the test programs aborted, put no explicit
      error code was set. This is changed now.

      ELPA_2013.11 release (minor version 000) · ea970032
      Andreas Marek authored
      This is the release of the ELPA_development_version_OpenMP
      If OpenMP support is not used, this version has the same
      functionality as ELPA_2013.08.
      
      If OpenMP support is used, obviously, a hybrid version of ELPA will be
      build.
      
      Allthough this is a release, version ELPA_2013.11 is far from complete!
      During the next week optimizations of the OpenMP part will be published,
      however, the basic functionality is set by this commit

      Introducing OpenMP functionality in ELPA_development_version_OpenMP · 48e712ef
      Andreas Marek authored
      This commit introduces OpenMP functionality in the
      ELPA_development_version_OpenMP branch.
      
      It contains several bugfixes to the OpenMP functionality in the
      branch "ELPA_development_version", the later will soon be deleted
      since the new branch is the new reference implementation.
      
      The current branch contains the following features/bugfixes:
      - building of the OpenMP version of ELPA via configure and the
        "--with-openmp" flag. The build library contains a "_mt"
        (multi-threaded) in its name.
        The configure procedure should (hopefully) determine for each
        compiler the neccessary OpenMP flags.
        If the "--with-openmp" flag is ommitted exactly the same code
        as in the ELPA 2013.08.001 release is used and build in the
        same way
      - The example test cases print which kernels have been used and
        how many OpenMP threads are used at runtime
      - correct handling of OpenMP stack arrays: the previous implementation
        caused compiler dependent segmentation faults
      - OpenMP capability with all available kernels: the correctness of
        the computations have been checked for all kernels except the
        Bluegene (P/Q) versions

      Debug output of test cases · 50a000db
      Andreas Marek authored
      For debugging purposes the test examples of the ELPA library can
      now write the Eigenvectors in an ascii file, e.g
      a call of "test_real 4000 1500 16 output" will envoke the test
      case for real matrices of the ELPA1 library. A matrix of 4000x4000
      values will be created an 1500 EV's will be computet with a 16 blocking.
      And the results will be --- due to the output flag --- written to a
      text file

      Volker Blum authored
      We have taken the unusual (one-time) step to modify the structure
      of the ELPA git repository as follows:
      
      1) The current ELPA version has been designated as a "stable"
         version. It has proven to be rock solid for us so far, and
         deserves this name.
      
      2) We have decided on a stable version naming scheme,
         "ELPA_year.month". The first such version is
         ELPA_2011.12. This version will only ever be updated
         for clear and unambiguous bug fixes.
      
      3) All further development will happen in the directory named
         ELPA_development_version. At this time, ELPA_2011.12 is an
         exact copy of ELPA_development_version.
      
      No substantial changes have been made to either repository as yet.
      (But we are happy to say that the present "ELPA" publication, which
      we hope ELPA users will cite, now has its final volume and page
      numbers.)
      
      We apologize if this change causes any inconvenience for you. Please
      try to make sure that any changes you might make really affect the
      development version, and not the stable version. We do not plan any
      structural changes of a similar scope at any point in the future,
      but it had to be done once.
      
      Happy ELPA stable version day!
