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

GPU Operation Mode

GOM allows one to reduce power usage and optimize GPU throughput by disabling GPU features.

Each GOM is designed to meet specific user needs.

Enumerator:

NVML_GOM_ALL_ON: Everything is enabled and running at full speed.
NVML_GOM_COMPUTE: Designed for running only compute tasks. Graphics operations < are not allowed.
NVML_GOM_LOW_DP: Designed for running graphics applications that don't require < high bandwidth double precision.

enum nvmlInforomObject_t

Available infoROM objects.

Enumerator:

NVML_INFOROM_OEM: An object defined by OEM.
NVML_INFOROM_ECC: The ECC object determining the level of ECC support.
NVML_INFOROM_POWER: The power management object.
NVML_INFOROM_COUNT: This counts the number of infoROM objects the driver knows about.

enum nvmlMemoryErrorType_t

Memory error types

Enumerator:

NVML_MEMORY_ERROR_TYPE_CORRECTED: A memory error that was corrected

For ECC errors, these are single bit errors For Texture memory, these are errors fixed by resend

NVML_MEMORY_ERROR_TYPE_UNCORRECTED: A memory error that was not corrected

For ECC errors, these are double bit errors For Texture memory, these are errors where the resend fails

NVML_MEMORY_ERROR_TYPE_COUNT: Count of memory error types.

enum nvmlMemoryLocation_t

Memory locations

Enumerator:

NVML_MEMORY_LOCATION_L1_CACHE: GPU L1 Cache.
