I proposed something this weekend (super late I know, sorry). Any idea when we'll know if we're presenting or not?

As a reviewer, I got a few codes for a free copy of "Vulkan 3D Graphics Rendering Cookbook". PM me if you'd like one, first come, first served :)

Seb wrote a fantastic article exploring how to make matrix multiplications go fast on AMD GPUs. This is a deep dive into both the algorithm and hardware, with great visualizations. He is also looking for work and I only have good things to say about him, so hire him! seb-v.github.io/optimization...

Hey there bsky! I'm looking for an internship in graphics/engine programming anywhere in the world (I'm willing to relocate). If you happen to know any open positions or if you work at a company that is taking interns, feel free to contact me! Portfolio ⬇️

Thanks! Want to grab a beer at some point after the holidays if you're still in Paris btw?

Oh I didn't know it had Tint and Naga now, nice! Thanks, TIL!

I'm not sure if there is something, I use PIX on windows to get the HLSL. It's ok if you don't have an easy way to get the code, I won't be able to test on Mac anyway.

I know the explanation is short but it would take quite a few tweets to fully go through it 😅

V0 is worse than original for testing, V1 is the original code, V2 is a failed fix, V3 fixes the execution sync issue but lacks a read after write synchronization. It seems the writes make it to memory fast enough though! The code is here if you want to take a look github.com/frguthmann/w...

I was looking at some code synchronizing multiple threadgroups within the same dispatch and I had a hunch something was off. There are actually multiple causes for the original race(s) so I wrote increasingly less racy versions of it, to validate my hunch and finally fix the original code.

Thanks! What did you test this on?

François Guthmann @frguthmann.bsky.social · 02/12/2024

Oh wow, interesting! I only inspected the generated HLSL and AMD ISA but I would have expected this to work on Apple devices as well, thanks for testing! Would it be easy for you to send me the generated MSL code?

Here's what I get: V0: ❌, V1: ❌, V2: ❌, V3: ✅, V4: ✅

Hey all, I wrote some WebGPU code to test some race conditions in a shader. If you're willing to try, let me know what you see. Red/flicker means there's a race. I'm especially curious about V3 which could theoretically race but I was never able to catch it. frguthmann.github.io/webgpu_racy_...

Yes, definitely! When rehearsing I always tried to phrase occupancy as *one* way to hide latency, but not sure how I did when presenting that day.

Sorry for the terrible photo quality, knees were weak and arms heavy :p. Also, shout-out to the first row who noticed I was taking a picture and decided to have fun with it 😁.

I would love a write up explaining the design choices, pitfalls avoided and so on afterwards!

Hey all, the Graphics Programming Conference is approaching. This is my first conference and I'm looking forward to meeting fellow graphics people in person. If you're coming and would like to meet, ping me! Even if we don't know each other :)

After 1.5 years at AMD, here is finally my first blog post on GPUOpen 🥳. Let's demystify occupancy together ! Please feel free to reach out if you have questions or comments :) gpuopen.com/learn/occupa...

Occupancy explained

In this blog post we will try to demystify what exactly occupancy is, which factors limit occupancy, and how to use tools to identify occupancy-limited workloads.
