Hello Pavan,

Thank you for your reply,

Are you sure about that ?
I have downloaded MPICH-3.2 (The latest version) . According to the userguide, MPICH supports checkpoint/rollback fault tolerance and currently only the BLCR checkpointing library is supported. We can see this information at chapter 8 in this userguide https://www.mpich.org/static/downloads/3.2/mpich-3.2-userguide.pdf.

In addition, I also have downloaded the latest version of BLCR that supports recent linux kernels.

Hello,

BLCR checkpointing is no longer supported in MPICH.  The BLCR kernel module hasn't been updated to recent linux kernels, and move folks have moved to alternate checkpointing infrastructure such as FTI or SCR.  You might want to consider doing that as well.
