Code to gather information about exceptions on remote worlds
and rethrow to all ranks in all worlds.

Note: If this exception brings down the world, then some ranks may be
killed by the MPI system before the exception reaches _their_ top level.

Merge in /branches/windows_from_1456_trunk_1620_merged_in branch.

You will find a preserved pre-merge trunk in tags under tags/trunk_at_1625.
That will be useful for diffing & checking on my stupidity.

Here is a list of the conflicts and their resolution at this
point in time.


=================================================================================
(LLWS == looks like white space).

finley/src/Assemble_addToSystemMatrix.c - resolve to branch - unused var. may be wrong.....
finley/src/CPPAdapter/SystemMatrixAdapter.cpp - resolve to branch - LLWS
finley/src/CPPAdapter/MeshAdapter.cpp - resolve to branch - LLWS
paso/src/PCG.c - resolve to branch - unused var fixes.
paso/src/SolverFCT.c - resolve to branch - LLWS
paso/src/FGMRES.c - resolve to branch - LLWS
paso/src/Common.h - resolve to trunk version. It's omp.h's include... not sure it's needed,
but for the sake of saftey.....
paso/src/Functions.c - resolve to branch version, indentation/tab removal and return error
on bad unimplemented Paso_FunctionCall.
paso/src/SolverFCT_solve.c - resolve to branch version, unused vars
paso/src/SparseMatrix_MatrixVector.c - resolve to branch version, unused vars.
escript/src/Utils.cpp - resloved to branch, needs WinSock2.h
escript/src/DataExpanded.cpp - resolved to branch version - LLWS
escript/src/DataFactory.cpp - resolve to branch version
=================================================================================

This currently passes tests on linux (debian), but is not checked on windows or Altix yet.

This checkin is to make a trunk I can check out for windows to do tests on it.

Known outstanding problem is in the operator=() method of exceptions
causing warning messages on the intel compilers.

May the God of doughnuts have mercy on my soul.

The MPI branch is hereby closed. All future work should be in trunk.

Previously in revision 1295 I merged the latest changes to trunk into trunk-mpi-branch.
In this revision I copied all files from trunk-mpi-branch over the corresponding
trunk files. I did not use 'svn merge', it was a copy.

Parallelization using MPI for solution of implicit problems.

Parallelization for explicit problems has already been accomplished in
the main SVN branch.

This is incomplete and is not ready for use.

changes to escript/py_src/pdetools.py and /escript/src/Data.h/.cpp to
make the Locator work in MPI. escript::Data::mindp now returns a 3 tuple,
with the MPI rank of the process on which the minimum value occurs
included. escript::Data::convertToNumArrayFromDPNo also takes the ProcNo
to perform the MPI reduction.

This had to be implemented in both the MPI and non-MPI versions to allow
the necesary changes to the Python code in pdetools.py. In the non-MPI
version ProcNo is set to 0. This works for the explicit scripts tested
thus far, however if it causes problems in your scripts contact Ben or
Lutz, or revert the three files (pdetools.py, Data.h and Data.cpp) to
the previous version.

Changes relating to the MPI version of escript
The standard OpenMP version of escript is unchanged

- updated data types (Finley_Mesh, Finley_NodeFile, etc) to store meshes
  over multiple MPI processes.
- added CommBuffer code in Paso for communication of Data associated
  with distributed meshes
- updates in Finley and Escript to support distributed data and operations
  on distributed data (such as interpolation).
- construction of RHS in MPI, so that simple explicit schemes (such as
  /docs/examples/wave.py without IO and the Locator) can run in MPI.
- updated mesh generation for first order line, rectangle and brick
  meshes and second order line meshes in MPI.        
- small changes to trunk/SConstruct and trunk/scons/ess_options.py to
  build the MPI version, these changes are turned off by default.
