Abstract
One embodiment of the present disclosure sets forth a technique for enforcing cross stream dependencies in a parallel processing subsystem such as a graphics processing unit. The technique involves queuing waiting events to create cross stream dependencies and signaling events to indicated completion to the waiting events. A scheduler kernel examines a task status data structure from a corresponding stream and updates dependency counts for tasks and events within the stream. When each task dependency for a waiting event is satisfied, an associated task may execute.
