Dear all,
I'm trying to use LAM/MPI 7.1.1 with Berkeley Lab Checkpoint/Restart
0.4.0 and kernel 2.4.26. But I don't get things working correctly. Is
anybody using BLCR to checkpoint MPI applications?
I can checkpoint and restart sequential programs and programs that use
POSIX threads without problems. So, BLCR seams to work.
As described in the User's Guide, I start my MPI programs with
$ mpirun -np 3 -ssi rpi crtcp -ssi cr blcr checkpoint_mpi
When I call cr_checkpoint with the pid of mpirun only a single
checkpoint file with the context of mpirun is saved. But I cannot find
any context files of my applications. I also tried to linked my
application directly to libcr.so, but this did not help.
Has anybody an idea, what I could had made wrong?
Heiko
