Params for cuptiPmSamplingSetConfig.

Public Members

size_t structSize

[in] Size of the data structure.

void *pPriv

[in] Set to NULL.

CUpti_PmSampling_Object *pPmSamplingObject

[in] PM sampling object.

size_t configSize

[in] Size of the config image.

const uint8_t *pConfig

[in] Config image.

size_t hardwareBufferSize

[in] The hardware buffer size in which raw PM sampling data will be stored. These samples will be decoded to counter data image with cuptiPmSamplingDecodeData call.

uint64_t samplingInterval

[in] For the trigger mode CUPTI_PM_SAMPLING_TRIGGER_MODE_GPU_SYSCLK_INTERVAL, sampling interval is the number of sys clock cycles. For the trigger mode CUPTI_PM_SAMPLING_TRIGGER_MODE_GPU_TIME_INTERVAL, sampling interval is in nanoseconds.

CUpti_PmSampling_TriggerMode triggerMode

[in] Trigger mode. Note: CUPTI_PM_SAMPLING_TRIGGER_MODE_GPU_TIME_INTERVAL is not supported in Turing and GA100. Supported from GA10x onwards.

CUpti_PmSampling_HardwareBuffer_AppendMode hwBufferAppendMode

[in] Append mode for the records in hardware buffer. For KEEP_OLDEST mode, all the records will be kept in the buffer and in case hardware buffer is getting filled up. overflow will be set to 1 in CUpti_PmSampling_DecodeData_Params. For KEEP_LATEST mode, the new records will overwrite the oldest records in the buffer in case of filled buffer.
