# 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
