Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Vcc – The Vulkan Clang Compiler
See https://github.com/google/clspv for an OpenCL implementation on Vulkan Compute. There are plenty of quirks involved because the two standards use different varieties of SPIR-V ("kernels" vs. "shaders") and provide different guarantees (Vulkan Compute doesn't care much about numerical accuracy). The Mesa folks are also looking into this as part of their RustiCL (a modern OpenCL implementation) and Zink (implementing OpenGL and perhaps OpenCL itself on Vulkan) projects.

AMD's CDNA 3 Compute Architecture
Vulkan Compute backends for numerical compute (as typified by both OpenCL and SYCL) are challenging, you can look at Google's cspv https://github.com/google/clspv project for the nitty gritty details. The lowest-effort path is actually via some combination of Rocm (for hardware that AMD bothers to support themselves) and the Mesa project's Rusticl backend (for everything else).

WSL with CUDA Support
D3D12 has more compute features than Vulkan has. It works out for DXVK because games often don’t use those, but it’ll cause much more issues with CLon12.
By the way, if you are ready to have a _limited_ implementation without a full feature set because of Vulkan API limitations, clvk is a thing. The list of limitations of that approach is at https://github.com/google/clspv/blob/master/docs/OpenCLCOnVu...
tldr: Vulkan and OpenCL SPIR-V dialects are different, and the former has significant limitations affecting this use case

Low overhead C++ interface for Apple's Metal API
For OpenCL on DX12, the test suite doesn't pass yet. Every Khronos OpenCL 1.2 CTS test passes on at least one hardware driver, but there's none that pass them all. That is why CLon12 isn't submitted to Khronos's compliant products list yet.
The pointer semantics that Vulkan has aren't very amenable to implementing a compliant OpenCL implementation on top of. There are also some other limitatons: https://github.com/google/clspv/blob/master/docs/OpenCLCOnVu....

[Hardware Unboxed] - Apple M1 Pro Review - Is It Really Faster than Intel/AMD?
Vulkan is much more limited, notably because of Vulkan's SPIR-V dialect limitations. That makes a compliant OpenCL 1.2 impl on top of Vulkan impossible. (see: https://github.com/google/clspv/blob/master/docs/OpenCLCOnVulkan.md)

Cross Platform GPU-Capable Framework?
OpenCL really is your best bet for a cross-platform GPU-capable framework. OpenCL 3.0 cleared out a lot of the cruft from OpenCL 2.x so it's seeing a lot more adoption. The most cross-platform solution is still OpenCL 1.2, largely for MacOS, but OpenCL 3.0 is becoming more and more common for Windows and Linux and multiple devices. Even on platforms without native OpenCL support there are compatibility layers that implement OpenCL on top of DirectX (OpenCLOn12) or Vulkan (clvk and clspv).

Building the DirectX shader compiler better than Microsoft?
> We may support DXBC generation in Clang in the future (we mentioned that in the original proposal to LLVM). That work is unlikely to begin for a few years as our focus will be on supporting DXIL and SPIR-V generation first.
I appreciate this quote[0] from the microsoft camp. Setting clear expectations that something will not be done is a nice bit of fresh air.

Vcc – The Vulkan Clang Compiler
There's no need for transpilers these days, you can just compile HLSL to SPIR-V bytecode with dxc.

Shader Compilation
Use DXC and only HLSL for your main shader editing.

Apple's Game Porting Toolkit seems to have a D3DMetal.framework with full implementations of DirectX 12 to 9 on Metal
You can see libdxilconv in there, DXIL is the DirectX Intermediate Representation, documented in the open source shader compiler from Microsoft.

Proper way to access a read-only texture that has no sampler from an hlsl compute shader?
BTW, this problem can be reproduced as described below: - clone https://github.com/SaschaWillems/Vulkan.git - build the project and run it with arguments : -v - s hlsl to enable the validation layer and to use hlsl code - run ComputeShader project. The following validation error "Type mismatch on descriptor slot ..." will be shown in the console. - to fix it, as suggested above, you can replace the 3rd line of emboss.comp, sharpen.comp, and edgedetect.comp from: Texture2D inputImage : register(t0); //Creates validation errors to RWTexture2D inputImage : register(u0); //no validation errors (you'll then need to recompile the shaders to spv with a proper hlsl compiler such as Microsoft dxc)

Start project on Metal, port to DX11?
EDIT: There is also naga but it does not take HLSL as input: https://github.com/gfx-rs/naga but you can use DirectXShaderCompiler to compile to SpirV, then use naga to compile to Metal.

Using WebGPU as a graphics API for native C++ applications
🤨 For a "refusal to acknowledge it", they do appear to have a rather sizeable document mapping between HLSL and SPIR-V? https://github.com/microsoft/DirectXShaderCompiler/blob/main/docs/SPIR-V.rst

Is SPIRV-Cross a valid option to target Metal from HSSL?
I am starting work on a compute-driven rendering engine, and it seems that the best way to go around it will be to write code in HSSL, and then use DirectXShaderCompiler to generate SPIR-V, and SPIRV-Cross to then generate MSL. And while DXSC's repo has a page on incompatibilities, no such resource seems to exist for SPIRV-Cross targeting Metal.
