# 6.50. CUpti_ActivityMemcpy

struct CUpti_ActivityMemcpy

  The activity record for memory copies.

  (deprecated)

  This activity record represents a memory copy (CUPTI_ACTIVITY_KIND_MEMCPY).

  Public Members

  CUpti_ActivityKind kind

    The activity record kind, must be CUPTI_ACTIVITY_KIND_MEMCPY.

  uint8_t copyKind

    The kind of the memory copy, stored as a byte to reduce record size.

    CUpti_ActivityMemcpyKind

  uint8_t srcKind

    The source memory kind read by the memory copy, stored as a byte to reduce record size.

    CUpti_ActivityMemoryKind

  uint8_t dstKind

    The destination memory kind read by the memory copy, stored as a byte to reduce record size.

    CUpti_ActivityMemoryKind

  uint8_t flags

    The flags associated with the memory copy.

    See also

    CUpti_ActivityFlag

  uint64_t bytes

    The number of bytes transferred by the memory copy.

  uint64_t start

    The start timestamp for the memory copy, in ns.

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

  uint64_t end

    The end timestamp for the memory copy, in ns.

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

  uint32_t deviceId

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

  uint32_t contextId

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

  uint32_t streamId

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

  uint32_t correlationId

    The correlation ID of the memory copy.

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

  uint32_t runtimeCorrelationId

    The runtime correlation ID of the memory copy.

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

  uint32_t pad

    Undefined.

    Reserved for internal use.

  void *reserved0
