Ralph

When you say manually, do you mean setting these parameters in the
command line while calling mpirun, ompi-restart, and ompi-checkpoint? Or
is there another way to set these parameters?

Thanks

Ananda

You shouldn't have to, but there may be a bug in the system. Try
manually setting both envars and see if it fixes the problem.

I see that openmpi-sessions* directory is still getting created under
/tmp. How do I overcome this problem so that openmpi-sessions* directory
also gets created under the same directory I have defined for
"opal_cr_tmp_dir"?
