Also, you don't need to change the name from localhost unless you want to.

Folks
I have a program that does not have any shared memory parallelization. Thus even though the 16 processors of my quad socket / quad core machine are on the same motherboard, I need to have mpich2 up and running.

I need to get the machine a name so it isnt localhost
I start an mpd with no host name or node count
I fire up the job with an mpiexec -n 16

Or am I missing something here?  Do I need an mpdboot that fires up 16 daemons?

Should I be using gforker?? If so how is that done?
Thanks
- Andy
