[mpich-discuss] Runtime config file

[Pavan Balaji]

Jeff: I think Saurabh is referring to this from a sysadmin perspective, 
where one might want some settings to be automatically available for all 
users.

Saurabh: can you let me know what options you need to be set? There 
might be a different way to do this in Hydra.

What I am looking for is the equivalent of OpenMPI's etc/openmpi-mca-params.conf file. I am using Hydra process manager. Thank you.
