[mpich-discuss] MPICH2 Checkpointing Error with BLCR

[Manisha Chauhan]

Hi,

I am working on check-pointing my MPI application. I installed both hydra and blcr.  I have also checked "mpiexec --info" and it shows check pointing library as blcr, But still I am not able to checkpoint my application.

It makes a request of "requesting checkpoint"  and returned with "checkpoint completed" but the context file is empty. The next time it tries it end with the following error.


MPICH2 
version= 1.4.1

[mpiexec at tom-laptop] main (./ui/mpich/mpiexec.c:325): process manager error waiting for completion

Can you please help me  to find out the issue.

Regards
