Detailed Description

The OpenACC activity API part uses a CUpti_ActivityOpenAcc as a generic representation for any OpenACC activity. The 'kind' field is used to determine the specific activity kind, and from that the CUpti_ActivityOpenAcc object can be cast to the specific OpenACC activity record type appropriate for that kind.

Note that all OpenACC activity record types are padded and aligned to ensure that each member of the record is naturally aligned.

Field Documentation

CUDA context id Valid only if deviceType is acc_device_nvidia.

CUDA device id Valid only if deviceType is acc_device_nvidia.

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

CUDA stream id Valid only if deviceType is acc_device_nvidia.

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

CUPTI end timestamp

CUPTI OpenACC event kind (

See also:
CUpti_OpenAccEventKind)

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.

The kind of this activity.

CUPTI OpenACC parent construct kind (

See also:
CUpti_OpenAccConstructKind)
Note that for applications using PGI OpenACC runtime < 16.1, this will always be CUPTI_OPENACC_CONSTRUCT_KIND_UNKNOWN.
