Abstract: When generating a sequence of render outputs using a graphics processor, the completion status of rendering tasks for different render outputs is tracked so that processing tasks for later render outputs in the sequence of outputs can be processed concurrently with processing tasks for earlier render outputs in the sequence of outputs whilst ensuring that any dependencies between the rendering tasks are enforced.

Abstract: When performing a sequence of rendering jobs, rendering tasks for separate rendering jobs are permitted to overlap within the graphics processor's processing (shader) cores. A record is maintained of which rendering tasks are currently being processed by the graphics processor's processing (shader) cores which record can then be used to enforce any data (processing) dependencies between different rendering jobs.
