the solver seems to work now but simplesolve has still some problems

finally everthing for MPI is in the code. now testing is needed

Revision 1165 - (view) (annotate) - [select for diffs]
Modified Thu May 24 00:45:48 2007 UTC (11 years, 10 months ago) by ksteube
File length: 23013 byte(s)
Diff to previous 1140
Modified matrix/vector product in CSR format: for each row we
now precompute minimum index. In the loop over the non-zeros
of the row we then start at the precomputed min. This avoids
one of the if blocks and speeds up the floating point arith
quite a bit. May be able to get rid of the other if block
and speed it up further.

MPI branch trunk-mpi-branch has been merged with trunk through revision
1125, so changes in trunk since 1125 are not reflected in
trunk-mpi-branch.

Originally we parallelized revision 989, but after this merge it's
as if we'd parallelized revision 1125.

run_simplesolve.py runs on 1, 2, 4 CPUs.

the MPI version of PASO.PCG is running. 
There is a bug in the rectangular mesh generators but they need to be
revised in any case to clean up the code.

Branch for parallelization of implicit solutions.

This is a work in progress and should not yet be used by anyone.

The parallelization of explicit solutions was done by Ben and is
already incorporated into the main branch of trunk.
