Hi,
  The crash you report is likely something amiss with your source
compilation and/or the GPU drivers on your system. What version of
CUDA did you use for your source compilation? What driver version
is your test machine running?

Try running this command in VMD and tell me if it runs or crashes:
  vmdbench cudamadd
and then try:
  vmdbench cudabusbw

Let me know if those work or if they also trigger problems.

Cheers,
  John Stone
