There's been lots of turnover on the project recently so the previous experts for checkpoint/restart in MPICH are gone, but from what I can tell, it appears that it might currently be broken. This ticket (https://trac.mpich.org/projects/mpich/ticket/1144) is the only documentation about the subject that I can find, but I think the assumption is that everything has bit rotted and will need to be updated before it works again.

i created a checkpoint file of the integer sort NPB after 60 sec of running the application , the checkpoint file size is 121.6 MB (121,633,453 bytes).

i have Blcr for checkpoint/restart when i try to restart from the checkpoint file i had , nothing happened , it just hangs what i did wrong ? this is the command i used.
