Detailed Description

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

Field Documentation

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

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.

The ID of the device where the graph execution is occurring.

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.

The unique ID of the graph that is launched.

The activity record kind, must be CUPTI_ACTIVITY_KIND_GRAPH_TRACE

This field is reserved for internal use

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.

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