Graph

Warning

Experimental features:

• May be replaced, updated, or removed at any time.

• Do not require maintaining API/ABI stability of their own additions over time.

Motivation

This extension introduces functionality for recording enqueued operations into a graph for later execution. Queues can enter graph capture mode, where operations enqueued to them are recorded into a graph instead of being executed immediately. This graph can then be instantiated as an executable graph and appended to a queue multiple times for repeated execution.
