wsmp
----

The user forum at 
  http://www.alphaworks.ibm.com/tech/wsmp/forum
has only one entry - a question: how much memory does wsmp use?
It is dated 13 June, 2006.  There is no response.

douar_wsmp (GNU/Linux) and MPI
------------------------------

wsmp has these X86_64 builds for GNU/Linux
  GNU
  Intel
  PGI

MPI options include
  MPICH
  OpenMPI

We need to choose an MPI-compiler combination, in which the compiler
matches one of the wsmp builds.  The possibilites are different for 
each computer.

ace-net (mahone)
----------------
  mpich-1.2.7/SunStudio
    - no wsmp for this (Unless SunStudio is gnu-compatible ?)

  mpich-1.2.7/gnu
    - mpif90 not present
    - Ross Dickson reports:
        examples pwssmp_ex3.f and pwgsmp_ex1.f both segfault

  mpich-1.2.7/PGI
    - Ross Dickson reports:
      MPICH builds (of the wsmp examples) using PGI compilers were unsuccessful.
    - douar_wsmp reports (from the first call to wsmp):
      3 - MPI_COMM_SIZE : Null communicator
      [3]  Aborting program !
      [3] Aborting program!
      2 - MPI_COMM_SIZE : Null communicator
      [2]  Aborting program !
      [2] Aborting program!
      0 - MPI_COMM_SIZE : Null communicator

  openmpi-1.2.7/PGI-7.1
    - candidate *
    - examples have trouble...details on mahone...I forget right now.
    - The content of the .err file suggests that wsmp has accepted its license;
      however douar_wsmp reports a license problem:
        WSMP-> initialisation pb         -900

  mpich/gnu
    - candidate

  mpich/Intel
    - candidate

  OpenMPI/gnu
    - candidate *

  OpenMPI/Intel
    - candidate *


* possible gotcha - does wsmp *need* mpich.?
