Reports scheduling and delivery state for one parallel tile or band render call

Fields

• PageIndex is the zero-based loaded page that was rendered
• ColumnCount, RowCount and TileCount describe the calculated grid
• RequestedWorkerCount is the normalised caller request before the working-memory cap
• WorkerCount is the effective worker count after that cap
• CompletedTileCount counts worker bitmaps completed successfully
• DeliveredTileCount counts row-major callbacks completed before success, cancellation, or failure
• PeakConcurrentRenderStages is the highest number of workers rendering tiles at once
• BackpressureWaitCount counts waits by workers whose completed tile had not yet been delivered
• MemoryBudgetWorkerLimit is the worker cap derived from MaxWorkingBytes
• MaxWorkingBytes is the caller-supplied working-memory budget
• PeakTileReservationBytes is the largest conservative tile estimate
• PeakReservedRenderBytes is the highest summed reservation weight owned by the call
• PeakQueuedBytes is the conservative peak byte weight of completed tiles waiting for ordered delivery
• TotalMilliseconds is elapsed time from call entry until every worker has joined
• Cancelled reports cooperative callback cancellation
