Hello:

yes, I tried the CPU only version, it goes well and didn't stop. I am not sure whether I have ECC on or not. There are 4 Tesla K20 and one GTX650 in the workstation, after compilation, I simple submit the jobs with command:


mdrun -s md.tpr -gpu_id 0234

I submit the same system in another GTX690 machine, it also goes well..... I compiled Gromacs with the same options in that machine.

thank you very much
best
Albert

Have you tried running on CPUs only just to see if the issue persists?
Unless the issue does not occur with the same binary on the same
hardware running on CPUs only, I doubt it's a problem in the code.

Do you have ECC on?
