@ernire I personally think that people overestimate the market potential of hard-to-program computer systems. Most computers have to be programmable to most programmers. Most programs have to be programmed by most programmers. There is a very significant human factor in computing.

I'm an American Airlines diehard but this could change that.

Hey, @trebolloc @awnihannun, I wonder if you know of some member of the MLX community who would like to work on neural accelerators directly.

@never_released My kids are forced to use those, and I'm forced to buy it for them, which is really traumatic for me I gotta say. Look at screen and type all day? -> Here's the cheapest screen and keyboard China can make, kid. Have an old MBA you could use? -> Nope, not allowed.

tbh giving Chromebooks to pupils/students might be doing them a disservice imo :/ and Google doesn't seem too interested in fixing that

M5 Max is a local AI powerhouse in a laptop form factor. So awesome to see this thing released. Up to 8x faster prefill / image generation compared to M1 Max. Benchmarks done with MLX / mlx-lm.

@never_released Can I ask you to write some words about the really nice things you see becoming unblocked by that?

The feature ask at the very top of my list for Metal is to have a way to have the GPU device-side address match the host-side one. It'd actually unblock a number of really nice things.

@never_released C++ doesn’t support virtual aliases either; at best it happens to work sometimes. The proxy model is a view on what C++ itself might need to do.

GPUs and caches not handling aliasing: #virtual-aliasing-support" target="_blank" rel="nofollow noopener">docs.nvidia.com/cuda/cuda-prog… > If accessing same allocation through different “proxies” is required in the same kernel, a fence.proxy.alias can be used between the two accesses. The above example can thus be made legal with inline PTX assembly

@jimmyjames_tech @jonmasters Thanks for the kind words but all I contributed to this result is some mentorship and a fresh eye. This team had all the good ideas ready to go from the start of this cycle. I almost feel like I observed.

@jonmasters They have been making great strides on the gpu front for years, and @__simt__ has only accelerated that.

Anyone else appreciate how cool it is that @Arm v8 load-acquire/store-release OMCA semantics fit perfectly with C11 sequential consistency requirements?

The timing seems right to share that our paper "Towards Unified Analysis of GPU Consistency" has been accepted to ASPLOS. hernanponcedeleon.github.io/pdfs/asplos202…
Reese Levine@reeselevine

Just noticed the new sections on memory ordering/synchronization in MSL 3.2 (section 6.15 of developer.apple.com/metal/Metal-Sh…) Finally adding some useful primitives that open up the potential for a lot of interesting GPU compute algorithms on Apple silicon!

@code_report It’s wild that zipping the sources of K actually creates a BIGGER file!!! 🤯

Arthur Whitney for the first time ever has open sourced (under MIT license) K. This K is not the full K9 but is known as "K Junior." 4 files, 270 lines, 17K characters. You can find the zipped folder on shakti.com but I have put it on GitHub: github.com/codereport/kju…

Interested in the complicated and byzantine rules surrounding the C/C++ memory model? *Also* interested in the complicated and byzantine rules surrounding the C/C++ provenance model? Well, then have I got a C++ paper for you: wg21.link/P3292R0

@FelixCLC_ Nothing wrong with that. I have a talk on SIMT coming up and I feel the same way.

@cdiggins @lemire @Love2Code Opinion : it's the most important work in vectorization in this millennium, and its lessons need to be absorbed by implementers in order for anyone to be able to top it.
