6.36. CUpti_ActivityKernel2

struct CUpti_ActivityKernel2

The activity record for kernel.

(deprecated)

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_ActivityKernel9 activity record.

Public Members

CUpti_ActivityKind kind

The activity record kind, must be CUPTI_ACTIVITY_KIND_KERNEL or CUPTI_ACTIVITY_KIND_CONCURRENT_KERNEL.

uint8_t requested

The cache configuration requested by the kernel.

The value is one of the CUfunc_cache enumeration values from cuda.h.

uint8_t executed

The cache configuration used for the kernel.

The value is one of the CUfunc_cache enumeration values from cuda.h.

uint8_t sharedMemoryConfig

The shared memory configuration used for the kernel.

The value is one of the CUsharedconfig enumeration values from cuda.h.

uint16_t registersPerThread

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

uint64_t 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.

uint64_t 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.

uint64_t completed

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 deviceId

The ID of the device where the kernel is executing.

uint32_t contextId

The ID of the context where the kernel is executing.

uint32_t streamId

The ID of the stream where the kernel is executing.

int32_t gridX

The X-dimension grid size for the kernel.

int32_t gridY

The Y-dimension grid size for the kernel.

int32_t gridZ

The Z-dimension grid size for the kernel.

int32_t blockX

The X-dimension block size for the kernel.

int32_t blockY

The Y-dimension block size for the kernel.

int32_t blockZ

The Z-dimension grid size for the kernel.

int32_t staticSharedMemory

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

int32_t dynamicSharedMemory

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

uint32_t localMemoryPerThread

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

uint32_t localMemoryTotal

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

uint32_t 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 or runtime API activity record that launched the kernel.

int64_t gridId

The grid ID of the kernel.

Each kernel is assigned a unique grid ID at runtime.

const char *name

The name of the kernel.

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

void *reserved0

Undefined.

Reserved for internal use.
