[mpich-discuss] passing multiple environment variables to gforker

[Nichols A. Romero]

This is on my linux desktop which only has one cpu socket (hex core).
I thought that was the preferred method if there was only one cpu socket.

gforker is what I used with MacPorts on my mac laptop so I am familiar 
with it, but  I am willing to use any process manager that works.

Is there a reason for you to use gforker instead of the default process 
manager, Hydra?
