# 6.6. 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.
