2/3rd's ish compute, 1/3 other stuff from what I've seen. A good chunk of the compute are appliance-type boxes supporting simulation of particular embedded systems in a traditional environment. Most of the complexity comes from integration of these misc accessory systems. In general aside from the boxes handling the graphics projection, most of the 'compute' is idle a lot of the time, even when the simulator is running. There's usually a big burst of work to prep and load the simulation into the simulator, then minimal (but very latency sensitive) chatter back and forth between the various simulator components and the backend compute as the simulation runs.
