### Variables

int32_t CUpti_ActivityKernel2::blockX [inherited]

  The X-dimension block size for the kernel.

int32_t CUpti_ActivityKernel2::blockY [inherited]

  The Y-dimension block size for the kernel.

int32_t CUpti_ActivityKernel2::blockZ [inherited]

  The Z-dimension grid size for the kernel.

uint64_t CUpti_ActivityKernel2::completed [inherited]

  The completed timestamp for the kernel execution, in ns. It represents the completion of all it's child kernels and the kernel itself. A value of CUPTI_TIMESTAMP_UNKNOWN indicates that the completion time is unknown.

uint32_t CUpti_ActivityKernel2::contextId [inherited]

  The ID of the context where the kernel is executing.

uint32_t CUpti_ActivityKernel2::correlationId [inherited]

  The correlation ID of the kernel. Each kernel execution is assigned a unique correlation ID that is identical to the correlation ID in the driver or runtime API activity record that launched the kernel.

uint32_t CUpti_ActivityKernel2::deviceId [inherited]

  The ID of the device where the kernel is executing.

int32_t CUpti_ActivityKernel2::dynamicSharedMemory [inherited]

  The dynamic shared memory reserved for the kernel, in bytes.

uint64_t CUpti_ActivityKernel2::end [inherited]

  The end timestamp for the kernel execution, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the kernel.

uint8_t CUpti_ActivityKernel2::executed [inherited]

  The cache configuration used for the kernel. The value is one of the CUfunc_cache enumeration values from cuda.h.

int64_t CUpti_ActivityKernel2::gridId [inherited]

  The grid ID of the kernel. Each kernel is assigned a unique grid ID at runtime.

int32_t CUpti_ActivityKernel2::gridX [inherited]

  The X-dimension grid size for the kernel.

int32_t CUpti_ActivityKernel2::gridY [inherited]

  The Y-dimension grid size for the kernel.

int32_t CUpti_ActivityKernel2::gridZ [inherited]

  The Z-dimension grid size for the kernel.

CUpti_ActivityKind CUpti_ActivityKernel2::kind [inherited]

  The activity record kind, must be CUPTI_ACTIVITY_KIND_KERNEL or CUPTI_ACTIVITY_KIND_CONCURRENT_KERNEL.

uint32_t CUpti_ActivityKernel2::localMemoryPerThread [inherited]

  The amount of local memory reserved for each thread, in bytes.

uint32_t CUpti_ActivityKernel2::localMemoryTotal [inherited]

  The total amount of local memory reserved for the kernel, in bytes.

const char * CUpti_ActivityKernel2::name [inherited]

  The name of the kernel. This name is shared across all activity records representing the same kernel, and so should not be modified.

uint16_t CUpti_ActivityKernel2::registersPerThread [inherited]

  The number of registers required for each thread executing the kernel.

uint8_t CUpti_ActivityKernel2::requested [inherited]

  The cache configuration requested by the kernel. The value is one of the CUfunc_cache enumeration values from cuda.h.

void * CUpti_ActivityKernel2::reserved0 [inherited]

  Undefined. Reserved for internal use.

uint8_t CUpti_ActivityKernel2::sharedMemoryConfig [inherited]

  The shared memory configuration used for the kernel. The value is one of the CUsharedconfig enumeration values from cuda.h.

uint64_t CUpti_ActivityKernel2::start [inherited]

  The start timestamp for the kernel execution, in ns. A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the kernel.

int32_t CUpti_ActivityKernel2::staticSharedMemory [inherited]

  The static shared memory allocated for the kernel, in bytes.

uint32_t CUpti_ActivityKernel2::streamId [inherited]

  The ID of the stream where the kernel is executing.
