AFAIK it's not possible with MPICH unless you program it on your own  
at an application level. LAM/MPI has it built-in since 7.1, and for  
Open MPI it's scheduled for the upcoming 1.3 release.

There are Howtos for checkpointing of serial applications with SGE,  
but be aware the SGE will only "let's say" trigger an already  
existent checkpointing facility of the application (which already has  
to work without SGE).
