Well, I actually have to eat my words here. This code is alive and well. However, I don't think it does what you wanted or perhaps expected.
That param was intended to catch user-level mistakes whereby the user specified a tmpdir location via the tmpdir_base MCA param that the system admin wanted to protect. It was not intended for someone to specify locations to skip. So if you give that param and something violates it: Ralph:v1.4 rhc$ mpirun -n 2 -mca orte_tmpdir_base /foo/bar -mca orte_no_session_dirs /foo hostname -------------------------------------------------------------------------- The specified location for the temporary directories required by Open MPI is on the list of prohibited locations: Location given: /foo/bar Prohibited locations: /foo If you believe this is in error, please contact your system administrator to have the list of prohibited locations changed. Otherwise, please identify a different location to be used (use -h to see the cmd line option), or simply let the system pick a default location. -------------------------------------------------------------------------- I guess if you want to point it somewhere, your only option is to specify the orte_tmpdir_base param. There isn't a way to tell it "look everywhere BUT here".
