Category: New feature, Refactoring
Description:
Small refactor in executor - extract the backtracking of pass-through in the graph.
Originally it was used to obtain the group of tensor nodes that need to be treated
as outputs and buffered accordingly.
Use the functionality to pin the whole pass-through group when pinning a tensor.
Additional information:
Affected modules and functionalities:
Executor, graph
Key points relevant for the review:
Tests:
Make output buffers for arugment inputs to GPU operators pinned. #3728 didn't introduce additional tests for pinning, and I am not aware if we had any.
I'm not sure if we can easily observe the status of the outputs buffers outside of the operators or executor.
I might try to do something tomorrow, otherwise we will just have to observe the perf.I think I managed to write such test, inspecting the outputs of the executor for their pinnedness.
