Run two instances of Fluent. Start the first one normally, then for the second, run Fluent with the -t3 flag to create 3 threads, thereby using the other three processors.

But ensure that your two fluent instances are not using the same CPUs....

if your're running on a linux machine you can determine the process ids using "ps" command and then distribute the processes on the cpus with "taskset"....

that's how I'm doing it.
