I am getting a run-time error on my Linux workstation with K620 GPU
for the GPU version of GROMACS 5.0.5
using gcc 4.8.3 and CUDA Toolkit 7.0 I had no problem compiling the code
but got this error when starting a test case:
Program mdrun, VERSION 5.0.5
Source code file:
cudaStreamSynchronize failed in cu_blockwait_nb: an illegal memory
access was encountered
Searching the Web, I found that this type of error was already resolved
in GROMACS 4.6 some time ago.
Could somebody suggest a solution?
We have been able to compile and run GROMACS 5.0.4 on an older GPU with
compute capability 3.5,
my newer K620 has compute capability 5.0 - could this be the problem ?
