There was a problem hiding this comment.
Changes look good to me, same comment about merging 21.08 so CI passes

This PR refactors `device_scalar` to use a single-element `device_uvector` for its storage. This simplifies the implementation of device_scalar. Also changes the API of `device_scalar` so that its asynchronous / stream-ordered methods use the same API style (with explicit stream parameter) as `device_uvector` and `device_buffer`. Closes #570 This is a breaking change. When it is merged, PRs are likely to need to be merged immediately in other libraries to account for the API changes. - [x] cuDF: NVIDIA/cudf#8411 - [x] cuGraph: rapidsai/cugraph#1637 - [x] RAFT: NVIDIA/raft#259 - [x] ~cuML~ (unused) - [x] ~cuSpatial~ (unused) Authors: - Mark Harris (https://github.com/harrism) Approvers: - Rong Ou (https://github.com/rongou) - Jake Hemstad (https://github.com/jrhemstad) URL: #789

In comms/test.hpp `device_scalar::value` was not being passed an explicit stream, which means that the default stream was being synced. rapidsai/rmm#789 will remove the default from this parameter, and would have therefore broken the RAFT build. So this PR fixes the oversynchronization and ensures RAFT will build after the RMM PR is merged. Note this PR includes the cmake changes from NVIDIA#258 (just so I could build locally). Once NVIDIA#258 is merged this PR's changes will be simplified.
