/*! @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.
*/

The NVIDIA GDK provides a simple example program that shows how to build an
NVML client. When running an NVML client while the GDK is installed, be
sure your library path first includes the actual NVML library (installed
with the driver), not the stub library that exists solely for
compilation on systems without an NVIDIA driver available.
If you have installed this example code via your packaging system,
you should first copy it to a user directory before compilation.
The packaging system uninstall feature will not remove this directory if it
contains new files beyond what were installed as part of the GDK.
