Revision 1312 - (hide annotations)

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.
