How, do I set this up so it will run more then two(2) tasks at one time?

The projects are best handled one per processor. Part of the limit to this is the L2 Cache, as the projects need to use that a lot. If you ran 2 instances of SETI on a single processor it would take more than twice as long.

If you want speed, go to the number crunching forum and look for optimized applications. You can sometimes more than double the speed of work done.

If I’m reading your host page correctly you have a quad-CPU system, so you should be able to run four at a time. Go to the General preferences for your account, and under “Processor usage” set the “On multiprocessors, use at most” to the desired value. If you have four physical processors and can configure the system for “hyperthreading” or some such, you could conceivably benefit from entering a value of 8.
