Houdini 18.5 Executing tasks with PDG/TOPs pdg

pdg.workItemStatType module

Processing time statistics exposed by a PDG work item

This enum exposes the different time stamps that PDG records for each work item while it’s cooking. Work items that don’t actually cook, such as ones in an Attribute Create or Filter by Expression TOP, will have a value of 0 for all stat fields. Work items that cook from cached files on disk will also have a value of 0 for all stats.

Values

pdg.workItemStatType.CookEndTime

The time stamp recorded when the work item and any post cook callbacks are completed.

pdg.workItemStatType.CookStartTime

The time stamp recorded when the work item begins to cook. For items scheduled out of process, this stat is recorded once the scheduler receives a cook start notification from the evaluating work item process.

pdg.workItemStatType.FileSize

The total file size for all outputs of the work item.

pdg.workItemStatType.QueueTime

The time stamp for when the work item was first added to a scheduler job queue.

pdg.workItemStatType.ScheduleTime

The time stamp for when the work item was processed by a scheduler.
