2. Known Issues

This is a list of known NVML issues in the current driver:

  • On Linux when X Server is running nvmlDeviceGetComputeRunningProcesses may return a nvmlProcessInfo_t::usedGpuMemory value that is larger than the actual value. This will be fixed in a future release.
  • On Linux GPU Reset can't be triggered when there is pending GPU Operation Mode (GOM) change.
  • On Linux GPU Reset may not successfully change pending ECC mode. A full reboot may be required to enable the mode change.
  • nvmlAccountingStats supports only one process per GPU at a time (CUDA proxy server counts as one process).
  • nvmlAccountingStats_t.time reports time and utilization values starting from cuInit till process termination. Next driver versions might change this behavior slightly and account process only from cuCtxCreate till cuCtxDestroy.
  • On GPUs from Fermi family current P0 clocks (reported by nvmlDeviceGetClockInfo) can differ from max clocks by few MHz.
