mpiexec checkpointing error (RPi)

Question

When I try to run an application (just a simple hello_world.c doesn\'t work) I receive this error every time:

mpiexec -ckpointlib blcr -ckpoint-prefix /tmp/ -ckp         


        

Answer 1

Unfortunately, the checkpoint/restart code in MPICH 3.0.4 is known to be buggy at the moment. That will hopefully get fixed in a future release. It looks like you're probably using it correctly. It's possible that if you go back to a previous version, you might have better luck.

Answer 2

Here the problem was with the too small interval for checkpointing. Setting it to 20s or more has solved this (but not the other :( ) problem.
