Enumeration Type Documentation

enum nvmlBrandType_t

* The Brand of the GPU

enum nvmlClockId_t

Clock Ids. These are used in combination with nvmlClockType_t to specify a single clock value.

Enumerator:

NVML_CLOCK_ID_CURRENT

Current actual clock value.

NVML_CLOCK_ID_APP_CLOCK_TARGET

Target application clock.

NVML_CLOCK_ID_APP_CLOCK_DEFAULT

Default application clock target.

NVML_CLOCK_ID_CUSTOMER_BOOST_MAX

OEM-defined maximum clock rate.

enum nvmlClockType_t

Clock types.

All speeds are in Mhz.

Enumerator:

NVML_CLOCK_GRAPHICS

Graphics clock domain.

NVML_CLOCK_SM

SM clock domain.

NVML_CLOCK_MEM

Memory clock domain.

NVML_CLOCK_VIDEO

Video encoder/decoder clock domain.

enum nvmlComputeMode_t

Compute mode.

NVML_COMPUTEMODE_EXCLUSIVE_PROCESS was added in CUDA 4.0. Earlier CUDA versions supported a single exclusive mode, which is equivalent to NVML_COMPUTEMODE_EXCLUSIVE_THREAD in CUDA 4.0 and beyond.

Enumerator:

NVML_COMPUTEMODE_DEFAULT

Default compute mode -- multiple contexts per device.

NVML_COMPUTEMODE_EXCLUSIVE_THREAD

Support Removed.

NVML_COMPUTEMODE_PROHIBITED

Compute-prohibited mode -- no contexts per device.

NVML_COMPUTEMODE_EXCLUSIVE_PROCESS

Compute-exclusive-process mode -- only one context per device, usable from multiple threads at a time.

enum nvmlDriverModel_t

Driver models.

Windows only.

Enumerator:

NVML_DRIVER_WDDM

WDDM driver model -- GPU treated as a display device.

NVML_DRIVER_WDM

WDM (TCC) model (recommended) -- GPU treated as a generic device.

enum nvmlEccCounterType_t

ECC counter types.

Note: Volatile counts are reset each time the driver loads. On Windows this is once per boot. On Linux this can be more frequent. On Linux the driver unloads when no active clients exist. If persistence mode is enabled or there is always a driver client active (e.g. X11), then Linux also sees per-boot behavior. If not, volatile counts are reset each time a compute app is run.

Enumerator:

NVML_VOLATILE_ECC

Volatile counts are reset each time the driver loads.

NVML_AGGREGATE_ECC

Aggregate counts persist across reboots (i.e. for the lifetime of the device).

NVML_ECC_COUNTER_TYPE_COUNT

Count of memory counter types.

enum nvmlEnableState_t

Generic enable/disable enum.

Enumerator:

NVML_FEATURE_DISABLED

Feature disabled.

NVML_FEATURE_ENABLED

Feature enabled.

enum nvmlGpuOperationMode_t

NVML_GOM_COMPUTE
