[Mehmet Kurt]

Hi,

Is there any reason that might cause such a behavior?

Thank you,

Mehmet

I use a script file for both initial run and restart.

This is the command I use for initial run:

/home/kurt/mpich2-blcr-install/bin/mpiexec -env MPICH_ASYNC_PROGRESS 1 -disable-auto-cleanup -ckpointlib blcr -ckpoint-prefix ${CKPT_PATH} -f $hosts -np ${NUM_NODES}  ./md ${FREQUENCY} ${FAILING_IT}

And, this is for restart:

/home/kurt/mpich2-blcr-install/bin/mpiexec -env MPICH_ASYNC_PROGRESS 1 -disable-auto-cleanup -ckpointlib blcr -ckpoint-prefix ${CKPT_PATH} -ckpoint-num ${CK_NUM} -f $hosts -np ${NUM_NODES}

Mehmet

Can you send us the command lines you used for the initial run and when restarting?

Thanks,
