Properties

CurrentProcessGpuMemoryUsedBytes: VRAM (in bytes) currently allocated on this device by the current OS process, as reported by NVML (nvmlDeviceGetComputeRunningProcesses_v3). Returns 0 when the value can't be obtained (non-CUDA backend, NVML unavailable, or this process has not allocated GPU memory on this device).

CurrentProcessGpuUtilizationPercent: GPU compute (SM) utilization attributable to the current OS process on this device. 0-100 percentage averaged over the most recent NVML sampling window (~1-5 seconds depending on driver). Returns -1 when the value can't be obtained: non-CUDA backend, NVML unavailable, WSL2 / GRID where nvmlDeviceGetProcessUtilization is unsupported, insufficient permissions, or this process has had no GPU activity in the recent window. This is the per-process counterpart of GpuUtilizationPercent (which is device-wide).

GpuUtilizationPercent: Gets the current GPU compute utilization as a percentage (0-100), or -1 when utilization data is unavailable (non-NVIDIA backend or NVML query failure). On CUDA backends this maps to the NVML "gpu" utilization rate: the percent of time over the last sample period during which one or more kernels were executing.

GetDeviceFromNumber(int): Retrieves a GpuDeviceInfo object by its deviceNumber from the static Devices list.
