Package request: ZLUDA

[errnoh]

Project description

ZLUDA lets you run unmodified CUDA applications with AMD GPUs.

There was a recent good writeup of the capabilities at phoronix so I tried compiling it and running some cuda samples. Seemed to work fine.

Dependencies for building:

    rocmPackages.clr
    rocmPackages.miopen
    rocmPackages.rocm-smi
    rocmPackages.rocsparse
    rocmPackages.rocsolver
    rocmPackages.rocblas
    rocmPackages.hipblas
    rocmPackages.rocm-cmake
    rocmPackages.hipfft
    python3
    cargo
    rustc
    cmake
    clang
    zlib
    libxml2
    libedit

Additional build notes:

• as hipBLASLt is not available on nixpkgs I did comment out zluda_blaslt from Cargo.toml to be able to successfully build.

If no-one is interested I might end up packaging it myself at later date, but as I'm not that active on the ML space it might benefit from more active maintainer 🤷

Created a draft PR with my current progress. For some reason creating a nix-shell with the same buildinputs and running the cargo command manually builds fine. If someone has good ideas check the PR and the comment I added there.

is there any progress on this package request?

Actually, yes. @errnoh created a PR that was linked above: #288644

(Please create a comment in the feature request issue if you've a PR implementing it because else the people watching this don't get pinged!)

OK thank you. I'm a bit lost with when it will get finalised but great it's in progress. Thanks for your quick reply too

Good point, thought that just having the cross-mention does the trick but didn't consider watchers. Thanks for handling the reply though!

It's done when it's done ;)

If you want to help speed up the process, it'd be great if you could test the PR and report your findings.

I'm happy to help. I have no clue about testing and I only use github for nix config things.
Is there some testing documentation you can point me to?

Just https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md#how-to-review-pull-requests but the gist is to build the package locally and then test that build.

OK thanks for that. I read through it :)

ZLUDA v3 has now been merged. Worth mentioning that zluda_blaslt is not supported on this release and will be added later once hipblaslt package is available in nixpkgs. Everything else supported by ZLUDA should work fine though.

Sorry for commenting on a closed issue, but I got a new AMD motherboard for my laptop and wanted to give ZLUDA a try. From what I understand on the new blog post of vosen, ZLUDA 3 was based on ROCm version 5. Version 6 is available in nixpkgs, but there have been some problems, especially since miopen has some issues #299156 and is not available in the cache (version 6.x.y) -> takes ages to compile.

So to my question: should the current version of the package still use rocmPackages or should it be replaced with rocmPackages_5? I wanted to ask here instead of opening a new issue, but if isn't the right way, I can open one up :)

[Atemu]

Well that fully depends on whether it works or not. If it doesn't work with version 6 then it should be pinned to version 5.

ROCm 6 not being in the cache is not an issue of ZLUDA and the same is likely to happen to ROCm 5; it's a mess.

Haven't been following ZLUDA recently (apart from there being no releases since v3), but decided to take a look. Seems like there was a blog post couple weeks ago: https://vosen.github.io/ZLUDA/blog/zludas-third-life/

Seems like quite major changes but likely towards more stable future. Regarding the above questions it seems that at least regarding future versions one of the mentions over there is that Pre-rollback ZLUDA stayed on ROCm 5 mainly because I did not want to re-test all the version-specific workarounds. Since we are starting with a clean slate, AMD backend will target ROCm 6.1+.
