Hi Ralph.
I checked the errors.
I do not understand what the fololowing means : The session directory
location could not be parsed.
ompi-checkpoint attempted to use the session directory:
/tmp/openmpi-sessions-ndesai@vcainternmpi01_0
I opened the /tmp/openmpi-sessions-ndesai directory and various directories
are created.
Also, when I run the mpi program, I get the following errors before the
program starts running correctly:
[ndesai@vcainternmpi01 work]$ mpirun -am ft-enable-cr --np 16 ./DecoderTest
../../decoder/test.ini

I also checked the mca-params-conf file and all it contained were comments.
Do I have to make any changes there for getting correct snapshots?
Thanks a lot,
Neel.
