How to distribute no. of CPUs among parallel jobs?

Hello guys..... I'm a bit confused about how to make full use of the CFX license that we have for the current job. We have 4 parallel licenses, 4 unlimited licenses and 20 limited licenses in the server. Our gear is SGI machine that consists of 32 itanium Pentium chips. From my understanding, when running a parallel job, we need to assign 1 license for each CPU.
My problem currently used about 1.3million nodes. Should I assign more CPUs for each job to reduce no. of nodes per partition so that I can use limited licenses for the run as well? Thank you for your inputs here. |

Hi,
Why don't you just try it and find out? It will probably work nicely. Glenn Horrocks |

To run a parallel job, you need a single acfx_solver, a single acfx_parallel license, and one acfx_par_proc for each partition including the master. Look at how many par_proc licenses you have, that will determine how many partitions you can use.

Thanks, Jeff. You catch my question. It's actually the par_proc that limits the amount of CPUs that I can assign for a parallel job. I have 8 par_proc licenses in the server.
