Hi Shiquan,
Ross is correct here-- attempting to run GPU code from the login node will
result in errors. If you submit a job to run the tests, it should work
fine. I've been running Amber successfully on Keeneland with CUDA 4.2 on
the compute nodes but have encountered the problem you mentioned on the
login node.
Regards,
Robin Betz
