Is there a way to run two uniprocessor clients on Ubuntu? I have P4's in my servers now and F@h is only using half of the CPU's potential. I'd like to be able to run 2 clients but don't know how to go about it. Any help would be most appreciative! Thanks!

create 2 directories for the client and run the exe from inside each one. See the guide for installing on linux, and when you've done those steps make a copy of the fah directory and rename it (before you run it for the first time).

Please note that the P4 is a hyperthreading cpu, which means the OS believes there are two processors even though there is only one real processor. For certain types of workloads such as fileserver and database server, where the workload consists of extremely short bursts of processing, hyperthreading can increase throughput significantly over a more traditional single cpu. For workloads such as FAH where the calculations make use of the processor continuously, hyperthreading does not increase throughput. Running two clients will work, but in general, one will always be waiting for the other to release the arithmetic processor so both clients will run at about half the speed of one client.

The OS may be telling you that one client is only using half of the cpu's potential, but that information is misleading. You have already been using all of the potential.
