7.6. CUpti_ActivityCdpKernel#

struct CUpti_ActivityCdpKernel#

The activity record for CDP (CUDA Dynamic Parallelism) kernel.

This activity record represents a CDP kernel execution.

Public Members

CUpti_ActivityKind kind#

The activity record kind, must be CUPTI_ACTIVITY_KIND_CDP_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.

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 API activity record that launched the kernel.

int64_t gridId#

The grid ID of the kernel.

Each kernel execution is assigned a unique grid ID.

int64_t parentGridId#

The grid ID of the parent kernel.

uint64_t queued#

The timestamp when kernel is queued up, in ns.

A value of CUPTI_TIMESTAMP_UNKNOWN indicates that the queued time is unknown.

uint64_t submitted#

The timestamp when kernel is submitted to the gpu, in ns.

A value of CUPTI_TIMESTAMP_UNKNOWN indicates that the submission time is unknown.

uint64_t completed#

The timestamp when kernel is marked as completed, in ns.

A value of CUPTI_TIMESTAMP_UNKNOWN indicates that the completion time is unknown.

uint32_t parentBlockX#

The X-dimension of the parent block.

uint32_t parentBlockY#

The Y-dimension of the parent block.

uint32_t parentBlockZ#

The Z-dimension of the parent block.

uint32_t pad#

Undefined.

Reserved for internal use.

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.
