3.2. CUpti_ActivityAPI Struct Reference
[CUPTI Activity API]
This activity record represents an invocation of a driver or runtime API (CUPTI_ACTIVITY_KIND_DRIVER and CUPTI_ACTIVITY_KIND_RUNTIME).
Public Variables
- CUpti_CallbackId cbid
- uint32_t correlationId
- uint64_t end
- CUpti_ActivityKind kind
- uint32_t processId
- uint32_t returnValue
- uint64_t start
- uint32_t threadId
Variables
- CUpti_CallbackIdCUpti_ActivityAPI::cbid [inherited]
-
The ID of the driver or runtime function.
- uint32_t CUpti_ActivityAPI::correlationId [inherited]
-
The correlation ID of the driver or runtime CUDA function. Each function invocation is assigned a unique correlation ID that is identical to the correlation ID in the memcpy, memset, or kernel activity record that is associated with this function.
- uint64_t CUpti_ActivityAPI::end [inherited]
-
The end timestamp for the function, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the function.
- CUpti_ActivityKindCUpti_ActivityAPI::kind [inherited]
-
The activity record kind, must be CUPTI_ACTIVITY_KIND_DRIVER or CUPTI_ACTIVITY_KIND_RUNTIME.
- uint32_t CUpti_ActivityAPI::processId [inherited]
-
The ID of the process where the driver or runtime CUDA function is executing.
- uint32_t CUpti_ActivityAPI::returnValue [inherited]
-
The return value for the function. For a CUDA driver function with will be a CUresult value, and for a CUDA runtime function this will be a cudaError_t value.
- uint64_t CUpti_ActivityAPI::start [inherited]
-
The start timestamp for the function, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the function.
- uint32_t CUpti_ActivityAPI::threadId [inherited]
-
The ID of the thread where the driver or runtime CUDA function is executing.
