# 6.26. CUpti_ActivityGraphTrace2

struct CUpti_ActivityGraphTrace2

  The activity record for trace of graph execution.

  This activity record represents execution for a graph without giving visibility about the execution of its nodes. This is intended to reduce overheads in tracing each node. The activity kind is CUPTI_ACTIVITY_KIND_GRAPH_TRACE

  Public Members

  CUpti_ActivityKind kind

    The activity record kind, must be CUPTI_ACTIVITY_KIND_GRAPH_TRACE.

  uint32_t correlationId

    The correlation ID of the graph launch.

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

  uint64_t start

    The start timestamp for the graph execution, in ns.

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

  uint64_t end

    The end timestamp for the graph execution, in ns.

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

  uint32_t deviceId

    The ID of the device where the first node of the graph is executed.

  uint32_t graphId

    The unique ID of the graph that is launched.

  uint32_t contextId

    The ID of the context where the first node of the graph is executed.

  uint32_t streamId

    The ID of the stream where the graph is being launched.

  void *reserved

    This field is reserved for internal use.

  uint32_t endDeviceId

    The ID of the device where last node of the graph is executed.

  uint32_t endContextId

    The ID of the context where the last node of the graph is executed.
