Thanks again. I don't think the I/O bandwidth is issue. Because once I run the parallel with all time the run happening I am seeing the CPU usage as as 99% . So if that is an issue with I/O then the all process wont run at 99% right ?

When I forked out different process. Each will have the same priority right and I/O is the shared resource which should be equal to all process. that's what I am confussed

I am using top to determine the speed. is there is any utility which give more insights ?

OMPI-CHECKPOINT(1)						     Open MPI							OMPI-CHECKPOINT(1)

NAME
ompi-checkpoint, orte-checkpoint - Checkpoint a running parallel process using the Open MPI Checkpoint/Restart Service (CRS) NOTE: ompi-checkpoint, and orte-checkpoint are all exact synonyms for each other. Using any of the names will result in exactly identical behavior. SYNOPSIS
ompi-checkpoint [ options ] <PID_OF_MPIRUN> Options orte-checkpoint will attempt to notify a running parallel job (identified by mpirun) that it has been requested that the job checkpoint itself. A global snapshot handle reference is presented to the user, which is used in ompi_restart to restart the job. <PID_OF_MPIRUN> Process ID of the mpirun process. -h | --help Display help for this command -w | --nowait Do not wait for the application to finish checkpointing before returning. -s | --status Display status messages regarding the progression of the checkpoint request. --term After checkpointing the running job, terminate it. -v | --verbose Enable verbose output for debugging. -gmca | --gmca <key> <value> Pass global MCA parameters that are applicable to all contexts. <key> is the parameter name; <value> is the parameter value. -mca | --mca <key> <value> Send arguments to various MCA modules. DESCRIPTION
orte-checkpoint can be invoked multiple, non-overlapping times. It is convenient to note that the user does not need to spectify the checkpointer to be used here, as that is determined completely by each of the running process in the job being checkpointed. SEE ALSO
