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?
