Hello everyone,

I am doing research on the different migration mechanisms available for
MPI processes. I had a couple of questions I was hoping you guys you
clarify for me concerning this:

1. Are there other approaches to MPI migration that do not involve
checkpoint/restart mechanisms (e.g. LAM/MPI with BLCR, MPICH-V with BLCR
and Condor)?
2. MPI-2 allows for dynamic process spawning, is it possible to spawn an
MPI process on a different node and transfer the process state to the
newly created process as long as you keep account of the new location
for the other MPI processes?
3. MOSIX and Charm++ perform process migration with MPI processes, are
there any problems associated with using these systems for MPI process
migration?

Thanks!
Mauricio
