# 7.82. CUpti_ActivityMemset3

struct CUpti_ActivityMemset3

  The activity record for memset.

  (deprecated in CUDA 11.6)

  This activity record represents a memory set operation (CUPTI_ACTIVITY_KIND_MEMSET).

  Public Members

  CUpti_ActivityKind kind

    The activity record kind, must be CUPTI_ACTIVITY_KIND_MEMSET.

  uint32_t value

    The value being assigned to memory by the memory set.

  uint64_t bytes

    The number of bytes being set by the memory set.

  uint64_t start

    The start timestamp for the memory set, in ns.

    A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the memory set.

  uint64_t end

    The end timestamp for the memory set, in ns.

    A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the memory set.

  uint32_t deviceId

    The ID of the device where the memory set is occurring.

  uint32_t contextId

    The ID of the context where the memory set is occurring.

  uint32_t streamId

    The ID of the stream where the memory set is occurring.

  uint32_t correlationId

    The correlation ID of the memory set.

    Each memory set is assigned a unique correlation ID that is identical to the correlation ID in the driver API activity record that launched the memory set.

  uint16_t flags

    The flags associated with the memset.

    CUpti_ActivityFlag

  uint16_t memoryKind

    The memory kind of the memory set.

  uint64_t graphNodeId

    The unique ID of the graph node that executed this memset through graph launch.

    This field will be 0 if the memset is not executed through graph launch.

  uint32_t graphId

    The unique ID of the graph that executed this memset through graph launch.

    This field will be 0 if the memset is not executed through graph launch.

  uint32_t padding

    Undefined.

    Reserved for internal use.
