7.97. CUpti_ActivityPCSampling2

struct CUpti_ActivityPCSampling2

The activity record for PC sampling.

(deprecated in CUDA 9.0)

This activity records information obtained by sampling PC (CUPTI_ACTIVITY_KIND_PC_SAMPLING). PC sampling activities are now reported using the CUpti_ActivityPCSampling3 activity record.

Public Members

CUpti_ActivityKind kind

The activity record kind, must be CUPTI_ACTIVITY_KIND_PC_SAMPLING.

CUpti_ActivityFlag flags

The properties of this instruction.

uint32_t sourceLocatorId

The ID for source locator.

uint32_t correlationId

The correlation ID of the kernel to which this result is associated.

uint32_t functionId

Correlation ID with global/device function name.

uint32_t pcOffset

The pc offset for the instruction.

uint32_t latencySamples

Number of times the PC was sampled with the stallReason in the record.

These samples indicate that no instruction was issued in that cycle from the warp scheduler from where the warp was sampled. Field is valid for devices with compute capability 6.0 and higher

uint32_t samples

Number of times the PC was sampled with the stallReason in the record.

The same PC can be sampled with different stall reasons. The count includes latencySamples.

CUpti_ActivityPCSamplingStallReason stallReason

Current stall reason.

Includes one of the reasons from CUpti_ActivityPCSamplingStallReason
