AMD fail to realize software toolchain is what makes nvidia great. AMD thinks the hardware is all that’s needed

Nvidia's toolchain is really not great. Applications are just written to step around the bugs. ROCm has different bugs, which the application workarounds tend to miss.

Yes. This is what makes Nvidia's toolchain, if not great, at least ok. As a developer I can actually use their GPUs. And what I developed locally I can yhen run on Nvidia hardware in the cloud and pay by usage.

AMD doesn't seem to understand that affordable entry-level hardware with good software support is key.

Aside from the latest commit, there has been no activity for almost 3 years (latest code change on Feb 22, 2021). People are criticizing AMD for dropping this, but it makes sense to stop paying for development when the dev has stopped doing the work, no? And if he means that AMD stopped paying 3 years ago - well, that was before dinosaurs and ChatGPT, and alot has changed since then. https://github.com/vosen/ZLUDA/co…

This is really interesting (from the project's README):

> AMD decided that there is no business case for running CUDA applications on AMD GPUs.

Is AMD leadership brain-damaged, or something?

Phoronix Article from earlier(1):

"While AMD ships pre-built ROCm/HIP stacks for the major enterprise Linux distributions, if you are using not one of them or just want to be adventurous and compile your own stack for building HIP programs for running on AMD GPUs, one of the AMD Linux developers has written a how-to guide. "(1)

This event of release is however a result of AMD stopped funding it per "After two years of development and some deliberation, AMD decided that there is no business case for running CUDA applications on AMD GPUs. One of the terms of my contract with AMD was that if AMD did not find it fit for further development, I could release it. Which brings us to today." from https://github.com/vosen/ZLUDA?tab=readme-ov-file#faq…

Who was responsible at AMD for this project and why is he still not fired???????? How brain dead someone have to be to reject the major market share??????

I'm really rooting for AMD to break the CUDA monopoly. To this end, I genuinely don't know whether a translation layer is a good thing or not. On the upside it makes the hardware much more viable instantly and will boost adoption, on the downside you run the risk that devs will never support ROCm, because you can just use the translation layer. I think this is essentially the same situation as Proton+DXVK for Linux g…

I am surprised that everybody seem to have forgotten the (in)famous Embrace, Extend and Extinguish strategy.

It's time for Open Source to be on the extinguishing side for once.

Ah yes, so that one does seem to be a stumbling block. ROCm is not remotely convinced that running on gaming cards is a particularly useful thing. HN is really sure that being able to develop code on ~free cards that you've got lying around anyway is an important gateway to running on amdgpu.

The sad thing is people can absolutely run ROCm on gaming cards if they build from source. Weirdly GPU programmers seem determined to use proprietary binaries to run "supported" hardware, and thus stick with CUDA.

I don't understand why AMD won't write the names of some graphics cards under "supported", even if they didn't test them as carefully as the MI series, and I don't understand why developers are so opposed to compiling their toolchains from source. For one thing it means you can't debug the toolchain effectively when it falls over, weird limitation to inflict on oneself.

Strange world.

Hähnle is one of our best, that'll be solid. http://nhaehnle.blogspot.com/2024/02/building-hip-environmen.... Looks pretty similar to how I build it.

Side point, there's a driver in your linux kernel already that'll probably work. The driver that ships with rocm is a newer version of the same and might be worth building via dkms.

Very strange that the rocm github doesn't have build scripts but whatever, I've been trying to get people to publish those for almost five years now and it just doesn't seem to be feasible.

fertile soil for Alyssa and Asahi Lina :) https://rosenzweig.io/ https://vt.social/@lina

I know that Lina doesn't like a lot of the attention HN sends her way so it may be better if you don't link her socials here.

Sounds ridiculous, why have a public presence on a social network then?
