Subject: [OMPI devel] Checkpoint is broken in trunk
From: ananda.mudar_at_[hidden]
Date: 2010-09-17 10:14:53


I downloaded the nightly build of the trunk (r23756) and found that the checkpoint functionality is broken. My MPI program is a simple helloworld program incrementing and printing the number every few seconds once.
 
Following are the steps:
1. mpirun with NP set to 32
2. call ompi-checkpoint with "-term" option and it terminate the program after successful checkpoint image creation
3. call ompi-restart using the checkpoint image and it terminates with segmentation fault
 
I tried these steps with 1.5rc6 and 1.4.2 and I am able to restart the process using the checkpoint image. Am I missing any steps here? Reducing the number of processes didn't change the behavior.
 
Following is the output from my checkpoint attempt:
