[mpich-discuss] MPICH2 CPUs Vs. Cores

[Peter Willis]

Hello,

I have a single system with 4 CPUs. Each CPU has 12 cores.(48 cores total)
MPICH2 is built and installed from source and there are no errors.

The documentation is a bit vague regarding CPUs  vs. Cores.

QUESTIONS:

1.)
What is the best way for a single node system to utilize
a maximum number of cores?

2.)
Do I need PBS or Hydra to run jobs on a single node?



Thanks

Peter
