Cosmos 2008 on power computer

My machine: 2 Quad-core AMD CPU, 16 MB RAM, 64 bit system,Windows XP pro, Cosmos Professional 2008 SP3.1
Is there any way to setup Cosmos to utilize all the power that thismachine has. For example, when I run a Drop-Test on a complexassembly, I can see that one processor (random) works 90-100% andthe others like overflowing, work with 10-20% of their capacity.Why?
So, when we run SolidWorks 2008 64 or any of the professionalpackage add-ons (excluding COSMOS), we are able to leverage all 8processors. When running COSMOS, only one of the 8 processors isbeing used.
See attached image, performance of CPU usage in the Windows TaskManager.
Let me know if you have any suggestion.
