i need to use DMTCP to checkpoint and restart OpenMPI program
DMTCP was installed on my machine
and openmpi run normally
so i ran the following command:
:~$ dmtcp_checkpoint mpirun -np 4
/home/basma/NPB3.3/NPB3.3/NPB3.3-MPI/bin/is.A.4
my program is MPI/C Integer Sort of Nas Parallel Benchmark which run using 4
processes
then i created a manual checkpoint using the dmtcp_coordinator
so i had the following files in my home folder:
ckpt_orterun_5721e6a7ff40367d-2937-52471e26.dmtcp
ckpt_is.A.4_5721e6a7ff40367d-2942-52471e26.dmtcp
ckpt_is.A.4_5721e6a7ff40367d-2944-52471e26.dmtcp
ckpt_is.A.4_5721e6a7ff40367d-2947-52471e26.dmtcp
ckpt_is.A.4_5721e6a7ff40367d-2950-52471e26.dmtcp
dmtcp_restart_script.sh
dmtcp_restart_script_5721e6a7ff40367d-2937-52471e26.sh
i used the following command to restart:
basma@basma-Satellite-A500:~$ ./dmtcp_restart_script.sh
dmtcp_checkpoint (DMTCP + MTCP) 1.2.8
