Namespace: ManagedCuda.Nvml
Assembly: ManagedNvml.dll
Syntax
[Flags]
public enum nvmlClocksThrottleReason : ulong

Fields

Name Description
All

Bit mask representing all supported clocks throttling reasons. New reasons might be added to this list in the future
ApplicationsClocksSetting

GPU clocks are limited by current setting of applications clocks
GpuIdle

Nothing is running on the GPU and the clocks are dropping to Idle state
HwSlowdown

HW Slowdown (reducing the core clocks by a factor of 2 or more) is engaged

This is an indicator of:

  • temperature being too high

  • External Power Brake Assertion is triggered (e.g. by the system power supply)

  • Power draw is too high and Fast Trigger protection is reducing the clocks

  • May be also reported during PState or clock change

  • This behavior may be removed in a later release.
None

Bit mask representing no clocks throttling. Clocks are as high as possible.
SwPowerCap

SW Power Scaling algorithm is reducing the clocks below requested clocks
SyncBoost

Sync Boost. This GPU has been added to a Sync boost group with nvidia-smi or DCGM in order to maximize performance per watt. All GPUs in the sync boost group will boost to the minimum possible clocks across the entire group. Look at the throttle reasons for other GPUs in the system to see why those GPUs are holding this one at lower clocks.
Unknown

Some other unspecified factor is reducing the clocks
