[Openmp-commits] [PATCH] D104418: [PoC][WIP][OpenMP][Offloading] Fixed data race in libomptarget caused by async data movement

[Jon Chesterfield via Phabricator via Openmp-commits]

JonChesterfield added a comment.

This seems very coarse. If we want to schedule one task after another, we should use an API that adds that dependency edge. Using one for 'wait until everything is done, then continue' means as soon as one of those is scheduled, unrelated tasks slow down.

Is this only applicable per-async-object, and thus only affects a single async sequence?

Our async API could do with some cleanup and documentation to define what the constraints on it are.
