Detailed Description

This activity record represents a kernel execution (CUPTI_ACTIVITY_KIND_KERNEL and CUPTI_ACTIVITY_KIND_CONCURRENT_KERNEL) but is no longer generated by CUPTI. Kernel activities are now reported using the CUpti_ActivityKernel5 activity record.

Field Documentation

int32_t CUpti_ActivityKernel::blockX

The X-dimension block size for the kernel.

int32_t CUpti_ActivityKernel::blockY

The Y-dimension block size for the kernel.

int32_t CUpti_ActivityKernel::blockZ

The Z-dimension grid size for the kernel.

uint8_t CUpti_ActivityKernel::cacheConfigExecuted

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

uint8_t CUpti_ActivityKernel::cacheConfigRequested

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

uint32_t CUpti_ActivityKernel::contextId

The ID of the context where the kernel is executing.

uint32_t CUpti_ActivityKernel::correlationId

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 API activity record that launched the kernel.

uint32_t CUpti_ActivityKernel::deviceId

The ID of the device where the kernel is executing.

int32_t CUpti_ActivityKernel::dynamicSharedMemory

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

uint64_t CUpti_ActivityKernel::end

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.

int32_t CUpti_ActivityKernel::gridX

The X-dimension grid size for the kernel.

int32_t CUpti_ActivityKernel::gridY

The Y-dimension grid size for the kernel.

int32_t CUpti_ActivityKernel::gridZ

The Z-dimension grid size for the kernel.

CUpti_ActivityKind CUpti_ActivityKernel::kind

The activity record kind, must be CUPTI_ACTIVITY_KIND_KERNEL or CUPTI_ACTIVITY_KIND_CONCURRENT_KERNEL.

uint32_t CUpti_ActivityKernel::localMemoryPerThread

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

uint32_t CUpti_ActivityKernel::localMemoryTotal

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

const char* CUpti_ActivityKernel::name

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

uint32_t CUpti_ActivityKernel::pad

Undefined. Reserved for internal use.

uint16_t CUpti_ActivityKernel::registersPerThread

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

void* CUpti_ActivityKernel::reserved0

Undefined. Reserved for internal use.

uint32_t CUpti_ActivityKernel::runtimeCorrelationId

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

uint64_t CUpti_ActivityKernel::start

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_ActivityKernel::staticSharedMemory

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

uint32_t CUpti_ActivityKernel::streamId

The ID of the stream where the kernel is executing.
