/*! @page KnownIssues Known issues in the current version of NVML library
|
|
*
|
|
* This is a list of known NVML issues in the current driver:
|
|
* - NVML Field Values from #251 - #273 (Power Smoothing, Clock Event Reason, and Sync Power Balancing related field values) have changed between 13.0 and 13.0U1/v580TRD2.
|
|
* - Any application that is using these field IDs must be recompiled using the NVML header file from CUDA 13.0 Update 1 in order to continue working correctly with NVIDIA drivers v580 TRD2 and beyond.
|
|
* - On systems where GPUs are NUMA nodes, the accuracy of FB memory utilization provided by NVML depends on the memory accounting of the operating system.
|
|
* This is because FB memory is managed by the operating system instead of the NVIDIA GPU driver.
|
|
* Typically, pages allocated from FB memory are not released even after the process terminates to enhance performance. In scenarios where
|
|
* the operating system is under memory pressure, it may resort to utilizing FB memory. Such actions can result in discrepancies in the accuracy of memory reporting.
|
|
* - 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.
|
|
* - \ref nvmlAccountingStats supports only one process per GPU at a time (CUDA proxy server counts as one process).
|
|
* - \ref 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 \ref nvmlDeviceGetClockInfo) can differ from max clocks by few MHz.
