Use for the parallel flow continuation point.

All parallel flow instances are equivalent and connected to the same Begin or Next events that happened previously. An example of a flow start point is job scheduling. For instance, IJobParallelForExtensions.Schedule generates an implicit Begin Profiler flow event and IJobParallelFor.Execute generates an implicit ParallelNext event.

static void ScheduleParallelTask() { using (k_ScheduleParallelTasksMarker.Auto()) { var flowId = ProfilerUnsafeUtility.CreateFlow(ProfilerUnsafeUtility.CategoryScripts); // Mark the parent k_ScheduleParallelTasksMarker as a beginning of the flow ProfilerUnsafeUtility.FlowEvent(flowId, ProfilerFlowEventType.Begin); var thread = new Thread(() => EmitFlowEventAndChainThread(flowId)); thread.Start(); } } }
