Dear all,
Recently I always encounter cuda error when running NAMD (version 2.11). These errors occur usually 1 to 2 days after the simulation begins, and they are different from time to time. Sometimes the error is:
    FATAL ERROR: CUDA error memcpy to patch_pairs on Pe 1 (bogon device 0): unknown error; but sometimes it is: FATAL ERROR: cuda_check_progress polled 1000000 times over 100.545315 s on step 2239993....Could you tell me what is the cause of these errors? I will greatly appreciate you help.
Best regards,
Yeping Sun
