[mvapich-discuss] [MVAPICH2] Suspend / Resume

[wei huang]

Hi Yann,

Thanks for using mvapich2.

May I have you clarify your question a bit more? Typically SIGSTOP is to
pause the program and SIGCONT is to restart that program. Is this what you
want to have?

If you want to suspend a MPI job and restart later. May I suggest you to
use the checkpoint/restart function of the latest mvapich2 release.
Detailed instructions can be found at:

Please note that you need BLCR installed on your systems.

Let us know if we undertand your question correctly.

Thanks.

Regards,
Wei Huang
