Description

Contributes to rapidsai/build-planning#102

Some RAPIDS libraries are using ncclCommSplit(), which was introduced in nccl==2.18.1.1. This is part of a series of PRs across RAPIDS updating libraries' pins to nccl>=2.18.1.1 to ensure they get a new-enough version that supports that.

I've seen the C++ tests here fail consistently in the same way here, on other PRs, and on nightlies. Opened #2450 to document it. @cjnolet could you look into that or tag in someone who could?

Updated to pull in #2453, which temporarily skips one failing test that was blocking this.

When you have a chance James, could you please let me know what you think on this question ( rapidsai/build-planning#102 (comment) )?

Asking as the answer may mean adjusting the NCCL pin

Oh interesting that the bot merged this without a /merge comment. Someone must have clicked the automerge button in the UI (it wasn't me).

Anyway, I would have supported that anyway... as described in rapidsai/build-planning#102 and the PR description, raft is using NCCL APIs first introduced in NCCL 2.18.1 so it absolutely should have a floor of at least that version.

Now that this is merged, I'll answer the question over on rapidsai/build-planning#102 @jakirkham

A user commented /merge then deleted their comment trying to prevent the merge. Unfortunately, the bot was faster and merged the PR.

Follow-up to #2443

As part of the work to support NumPy 2 across RAPIDS, we found reason to upgrade some libraries like `cugraph` to slightly newer NCCL (`>=2.19`). Context: rapidsai/build-planning#102 (comment)

This applies that same bump here, to keep the range of NCCL versions consistent across RAPIDS.
