Zig and GPUs

- GPU programming is evolving with modern languages like Rust and Zig, reducing reliance on C++ and vendor-specific tools.
- Zig's GPU backend supports SPIR-V for Vulkan and OpenCL, and can generate PTX for NVIDIA and AMDGCN for AMD GPUs.
- Vulkan and OpenCL differ in capabilities, with OpenCL supporting more features like Kernel and Addresses, leading to higher test pass rates in Zig.
- Challenges include managing address spaces in SPIR-V and differences in hardware-accelerated math instructions between Vulkan and OpenCL.
- Future goals include improving SPIR-V validation, increasing test pass rates, adding CUDA/HIP bindings, and expanding GPU-compatible algorithms in Zig's stdlib.
