## Field Documentation

uint32_t CUpti_ActivityOpenAccLaunch::cuContextId

CUDA context id Valid only if deviceType is acc_device_nvidia.

uint32_t CUpti_ActivityOpenAccLaunch::cuDeviceId

CUDA device id Valid only if deviceType is acc_device_nvidia.

uint32_t CUpti_ActivityOpenAccLaunch::cuProcessId

The ID of the process where the OpenACC activity is executing.

uint32_t CUpti_ActivityOpenAccLaunch::cuStreamId

CUDA stream id Valid only if deviceType is acc_device_nvidia.

uint32_t CUpti_ActivityOpenAccLaunch::cuThreadId

The ID of the thread where the OpenACC activity is executing.

uint64_t CUpti_ActivityOpenAccLaunch::end

CUPTI end timestamp

CUpti_OpenAccEventKind CUpti_ActivityOpenAccLaunch::eventKind

CUPTI OpenACC event kind (

See also:
  CUpti_OpenAccEventKind)

uint32_t CUpti_ActivityOpenAccLaunch::externalId

The OpenACC correlation ID. Valid only if deviceType is acc_device_nvidia. If not 0, it uniquely identifies this record. It is identical to the externalId in the preceeding external correlation record of type CUPTI_EXTERNAL_CORRELATION_KIND_OPENACC.

CUpti_ActivityKind CUpti_ActivityOpenAccLaunch::kind

The activity record kind, must be CUPTI_ACTIVITY_KIND_OPENACC_LAUNCH.

uint64_t CUpti_ActivityOpenAccLaunch::numGangs

The number of gangs created for this kernel launch

uint64_t CUpti_ActivityOpenAccLaunch::numWorkers

The number of workers created for this kernel launch

uint32_t CUpti_ActivityOpenAccLaunch::pad1

Undefined. Reserved for internal use.

uint64_t CUpti_ActivityOpenAccLaunch::start

CUPTI start timestamp

uint32_t CUpti_ActivityOpenAccLaunch::threadId

ThreadId

uint64_t CUpti_ActivityOpenAccLaunch::vectorLength

The number of vector lanes created for this kernel launch
