CUDA 12 Support #1201

quasiben · 2023-06-22T16:58:54Z

Adds CUDA 12 Support to build matrix

Fixes #1115

jakirkham · 2023-06-22T17:44:22Z

Thanks Ben! 🙏

Would suggest looking at the RMM CUDA 12 PR ( rapidsai/rmm#1223 ) and lining this up with that

dependencies.yaml

jakirkham · 2023-06-22T19:07:07Z

Think we may also want these GHA changes

Not seeing any environment files here

Also pyproject.toml, which the Conda recipe pulls from, doesn't appear to have any CUDA specific changes needed

So that may be it

bdice · 2023-06-22T19:45:59Z

I agree with all @jakirkham's suggestions above. Maybe also need updates for docs/source/install.rst?

jakirkham · 2023-06-22T19:51:49Z

Thanks Bradley! 🙏

Good catch. Yeah this cudatoolkit here should be changed to cuda-version

https://github.com/rapidsai/dask-cuda/blame/83c64765ec6612cb7c04b077e30edf6f846d90e0/docs/source/install.rst#L19

pentschev · 2023-06-23T14:34:14Z

I pushed GHA and docs changes.

@jakirkham @bdice could you check that the docs is correct, is that supposed to work for both CUDA 11.x and 12.x, or the correct way to document it is CUDA 11.x requires cudatoolkit=11.x and CUDA >= 12.x requires cuda-verison=12.x?

pentschev · 2023-06-23T16:42:41Z

Also seems like cuCIM needs to be handled before Dask-CUDA.

jakirkham · 2023-06-23T18:06:15Z

cuda-version should work on both CUDA 11 & 12

Ok could you please add cuCIM to the list in this issue ( #1115 )?

I'm not quite sure what's going on in the CUDA 12 tests, it seems Numba is failing to find NVVM files:

@bdice @jakirkham do you know if we're missing something here? Also cc @gmarkall for Numba, in case you have suggestions.

jakirkham · 2023-06-27T16:14:06Z

Yeah numba needs cuda-nvcc installed

This is needed to get nvvm, cudart & compilers

pentschev · 2023-06-27T19:10:50Z

Yeah numba needs cuda-nvcc installed

Shouldn't this be provided when Numba gets installed then? Note that it happens during a test, and I don't think Dask-CUDA should be requiring cuda-nvcc at runtime.

bdice

Requesting a small change to use cuda-version in dependencies.yaml.

bdice · 2023-06-27T19:15:23Z

dependencies.yaml

@@ -59,6 +59,10 @@ dependencies:
              cuda: "11.8"
            packages:
              - cudatoolkit=11.8


Can we change all these entries like the example below? This is needed to constrain the CUDA version of the RAPIDS packages used for Python testing. (It may be possible to derive the correct constraint from a pin on cudatoolkit but that's going to be less direct for the environment solver.)

Suggested change

- cudatoolkit=11.8

- cuda-version=11.8

- cudatoolkit

jakirkham · 2023-06-27T19:20:22Z

Similar to ucx, which can operate without cudatoolkit, numba doesn't require cuda-nvcc (except when CUDA is used). So it is up to us to install this when we need it

Edit: Maybe we can handle this on the cuDF side

Numba is an optional dependency, so the user will certainly need to satisfy that when using Numba+Dask-CUDA but without RAPIDS. I'm guessing we will want to update Numba's installation instructions for CUDA 12 too?

jakirkham · 2023-06-27T19:58:13Z

Yeah that's a good idea. Could you please raise an issue on the Numba repo and cc me?

pentschev · 2023-06-27T20:16:05Z

@jakirkham raised the issue in numba/numba#9045

pentschev · 2023-06-27T20:46:36Z

Yeah numba needs cuda-nvcc installed

This is needed to get nvvm, cudart & compilers

Adding cuda-nvcc raised a different error now:

cuda-nvcc: Please add the `compiler("c")` and `compiler("cxx")` packages to the environment.

It seems that this can't be added as a runtime dependency, is that the case?

jakirkham · 2023-06-27T21:48:05Z

Thanks Peter! 🙏

This could be worked around by adding the c-compiler & cxx-compiler packages. Alternatively cuda-compiler pulls both of them in for us

That said, it seems reasonable to harden this requirement in cuda-nvcc. Submitted upstream PR ( conda-forge/cuda-nvcc-feedstock#21 )

pentschev · 2023-06-28T08:42:52Z

Thanks @jakirkham , after merging of conda-forge/cuda-nvcc-feedstock#21 all tests now pass! 😄

Do we need cuda-nvrtc for Numba?

You can get away without it if you're not linking .cu files with Python kernels or using float16. But for full functionality it should be present.

Added this suggestion below

jakirkham

Thanks Peter! 🙏

This is looking pretty good. Added a minor suggestion to include cuda-nvrtc based on the thread below

+              - cuda-nvcc


Suggested change

- cuda-nvcc

- cuda-nvrtc

From what I understand of @gmarkall 's suggestion we don't need cuda-nvrtc given we're not doing any linkage whatsoever in Dask-CUDA, thus I think we should have only cuda-nvcc here.

Ok will leave this here and we can revisit as needed
