HI, That looks like the driver does not work or is incompatible with the runtime. Please get the SDK, compile a simple program, e.g. deviceQuery and see if that works (I suspect that it won't).
Regarding your machines, just FYI, the Quadro 4000 is a pretty slow card (somewhat slower than a GTX 460) so you'll hava a quite strong resource imbalance: a lot of CPU compute power (2x Xeon 5xxx, right?) and little GPU compute power which will lead to the CPU idling while waiting for the GPU.
