LAM/MPI was able to checkpoint/restart an entire MPI job as you
mention. Open MPI is now able to checkpoint/restart as well. In the
past week I added to the Open MPI trunk a LAM/MPI-like checkpoint/
restart implementation. In Open MPI we revisited many of the design
decisions from the LAM/MPI development and improved on them quite a
bit. At the moment there is no documentation on how to use it (egg on
my face actually). I'm working on developing the documentation, and I
will send a note to the users list once it is available.
Cheers,
Josh

To migrate processes, you need to be able to checkpoint them. I
believe that LAM-MPI is the only MPI implementation that allows this,
although I have never used LAM-MPI.
Good luck.

Hello folks,
I am trying to write some fault-tolerance systems with the
following criteria:
1) Recover any software/hardware crashes
2) Dynamically Shrink and grow.
3) Migrate processes among machines.
Does anyone has examples of code? What MPI platform is recommended
to accomplish such requirements?
I am using three MPI platforms and each has it own issues:
1) MPICH2 - good multi-threading support, but bad fault-tolerance
mechanisms.
2) OpenMPI - Does not support multi-threading properly and cannot
have it trap exceptions yet.
3) FT-MPI - Old and does not support multi-threading at all.
Any suggestions?
