2026-04-02 21:37:33 +0200 <davean> tomsmeding: I know, its supported :)
2026-04-02 21:37:14 +0200 <davean> Ah yah for anyone in that ecosystem.
2026-04-02 21:37:12 +0200 <tomsmeding> davean: Futhark supports AMD GPUs :)
2026-04-02 21:36:51 +0200 <tomsmeding> there's also Metal on the nice Apple chips
2026-04-02 21:36:28 +0200 <davean> Its too bad, with the iGPUs and such floating around.
2026-04-02 21:36:04 +0200 <tomsmeding> that depends on funding, I think
2026-04-02 21:35:42 +0200 <davean> So no and never?
2026-04-02 21:35:33 +0200 <tomsmeding> there's plans for one
2026-04-02 21:35:23 +0200 <davean> tomsmeding: does it have an AMD backend these days that works?

2026-04-02 21:30:23 +0200 <tomsmeding> in any case, the people hacking on accelerate are aware of all this, but there's little incentive in the academic system to spend the hours to fix it
2026-04-02 21:29:41 +0200 <tomsmeding> yeah
2026-04-02 21:29:36 +0200 <davean> and I don't mean that encuragingly.

2026-04-02 21:29:32 +0200 <tomsmeding> davean: and very old stuff is more likely to still work than the fancy thing from 2 years ago
2026-04-02 21:29:30 +0200 <davean> Ah yah if you're trying to hook it yourself instead of use the compiler which is what their spec actually is ... good luck!
2026-04-02 21:28:58 +0200 <tomsmeding> doing this (instead of writing the CUDA glue code in C) was probably a mistake, and one that is in the plans of being fixed
2026-04-02 21:28:40 +0200 <tomsmeding> if you try to bind CUDA functions from Haskell, you're more exposed to the function name shuffling they do under the hood
2026-04-02 21:28:39 +0200 <davean> (I recently found out, because someone got me to fix the compile on an ancient game project)
2026-04-02 21:28:13 +0200 <davean> There is something more
2026-04-02 21:28:08 +0200 <davean> Hum, so CUDA software I have from 2008 still works fine.
2026-04-02 21:27:40 +0200 <tomsmeding> the former seems to be fine so far
2026-04-02 21:27:31 +0200 <davean> I get hesitant every time I consider designing something that relies on accelerate for this reason :)
2026-04-02 21:27:18 +0200 <tomsmeding> Mostly depends on how backwards-compatible LLVM's IR format is, and how backwards-compatible CUDA turns out to be next year round
2026-04-02 21:26:46 +0200 <tomsmeding> I dunno!
2026-04-02 21:26:40 +0200 <tomsmeding> the CPU backend worked well enough for a long time already, by the way; it was the GPU backend that was unstable
