It's very similar to the UD (United Devices) client I run for the cancer research project. Your computer is compared to their example computer for processor, RAM, Hard drive space allocated for the program, and network connection. This gives a comparison rating for that workstation (all of your workstations are separate and unique) and this is used in conjunction with units completed for your points awarded.
I've never bothered to really figure it out, but it goes with the basic premise of; the faster the computer, the more points you get.
