[SOLVED] "cudaEventElapsedTime failed in cu_event_elapsed: device not ready" error

Hi All

Please anyone help me? I am using gromacs that is a molecular dynamic software and uses cuda cores to improve simulation performance.
I encountered problem after installed cuda 8.0 toolkit and running simulation package. I am using linux ubuntu 16 distro.

i received below message after 2 hours of starting simulation.

Program gmx mdrun, VERSION 5.1.2
Source code file: /home/zekeriya/Downloads/gromacs-5.1.2/src/gromacs/gmxlib/cuda_tools/cudautils.cu, line: 163

Fatal error:
cudaEventElapsedTime failed in cu_event_elapsed: device not ready

Problem is related with 6 pin power connector.
Earlier i converted two 6-pin connector to one 8-pin connector and i encountered that problem.
After inserting 6 and 8 pin power connector seperately problem is solved.
