Description

On my machine with a GTX660Ti and CUDA 5.0 and driver 319.32, I get a failure due to change 43b41cb8 with a single tMPI thread (+OpenMP):

-------------------------------------------------------
Program mdrun, VERSION 4.6.4-dev-20131014-43b41cb
Source code file: /home/hess/gmx_rel4.6/src/mdlib/nbnxn_cuda/nbnxn_cuda.cu, line: 591

Fatal error:
cudaStreamSynchronize failed in cu_blockwait_nb: unspecified launch failure
