Dear Pavan, Thank you for your reply and information. I know you are one of the authorities of MPICH as your name is written in the userguide. in my previous email, I just want to make sure. Unfortunately, I really need this feature. Do you have any suggestion besides SCR. as far as i know, SCR needs modification to the code. Thank you in advance.

I'm sure about the fact that MPICH doesn't support BLCR anymore. :-) I'll make sure it's removed in the future versions of the userguide. Thanks for pointing it out.
BLCR kernel support was from my experience about an year ago, so things might have changed in that.

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.

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.

Dear all,
Please anyone tell me how to manually checkpoint mpiexec ? I have followed the instruction in this link https://wiki.mpich.org/mpich/index.php/Checkpointing. I used the following command to send SIGUSR1. nothing happened.
kill -SIGUSR1 [pid of mpiexec]
thank you in advance
regards,
