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.

Had to undo commit to new MPI branch. The changes went into the original and
not the branch. The files committed here are exactly the same as revision 969.

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.



Revision 790 - (view) (annotate) - [select for diffs]
Modified Wed Jul 26 23:12:34 2006 UTC (13 years, 3 months ago) by bcumming

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.

The sparse solver can be called by paso now. 

the building has been change to reduce some code redundancy:
now all scons SCscripts are importing scons/esys_options.py which
imports platform specific settings.
