Vulkan-ValidationLayers VS rust-gpu

If this works then it might actually be a game bug and the game I guess passes invalid shaders when the cache exists... but it seems to work fine on windows vulkan drivers. You could try to run the game with https://github.com/KhronosGroup/Vulkan-ValidationLayers

For debugging these kinds of issues, I would recommend enabling the synchronization validation layer.

I would use the debugger to produce a stack trace and look into the validation layers source code. https://github.com/KhronosGroup/Vulkan-ValidationLayers Then I would either file an issue or make a PR there.

Currently validation layers might generate false-positive errors: https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/3450

A'rightey... I was able to reproduce this issue with Sascha Willems basic triangle example, so I am fairly certain, that this is a bug. I've opened an issue.

I am really at loss here, I found this issue but it doesn't really help me (I am starting to doubt it's even possible, maybe I'm a clown and doing it wrong...)

Can you post a reproduction case at https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues so we can take a look at it.

Which is why a GPU debugger with frame tracing is so much better option.

By the way, there are actually ways to expose a print function on shader code, provided there is driver support.

Huh yeah. Looking through the header the function you want works with c but there are others using c++ features. The reason given is understandable.

Sounds cool, but this requires yet another language to learn[0]. As someone who only has limited knowledge in this space, could someone tell me how comparable is the compute functionality of rust-gpu[1], where I can just write rust?

I don't do anything related to data science, but I feel like doing it in Rust would be nice.

You get operator overloading, so you can have ergonomic matrix operations that are typed also. Processing data on the CPU is fast, and crates like https://github.com/EmbarkStudios/rust-gpu make it very ergonomic to leverage the GPU.

I like this library for creating typed coordinate spaces for graphics programming (https://github.com/servo/euclid), I imagine something similar could be done to create refined types for matrices so you don't do matrix multiplication matrices of invalid sizes

Do you mean rust-gpu?

And https://github.com/EmbarkStudios/rust-gpu/tree/main/examples with the wgpu runner (here it runs the compute shader)

I don't know how major they are considered, but Embark Studios is doing quite a bit of Rust in the open source space, most notably (IMO) rust-gpu and kajiya

The examples in the rust-gpu repository are a good place to start

There's another project that's similar that's being used by an actual game company: https://github.com/EmbarkStudios/rust-gpu

They see specific advantages here that would outweigh that negative. It's not my space (I play games, but know next to nothing about graphics programming), but there's at least one argument in the other direction.

Could this approach work for compute shaders (GPGPU) as well? So far, I think https://github.com/EmbarkStudios/rust-gpu is the state of the art in that area, but it adds a specific Rust compiler backend for generating SPIR-V rather than leaving that up to the driver. That seems more complicated than it needs to be... but maybe it has advantages too? Thoughts?

https://github.com/embarkstudios/rust-gpu Allows you to create shaders (kernals) in Rust.

Also Embark Studios (formers DICE people) is doing a lot of work with Rust, all open source like Rust GPU https://github.com/EmbarkStudios/rust-gpu
