[mpich-discuss] how to send a SIGUSR1 signal to mpiexec using BLCR?

[Pavan Balaji]

Please keep mpich-discuss cc'ed.

Can you make sure checkpointing is in fact enabled? (see the README + 
check the output of mpiexec -info). There was a problem where it was not 
being enabled by default and additional configure options had to be 
passed. This has been fixed, but might not be in the version you are using.
