@Slang is a shading language that makes it easier to build and
maintain large shader codebases in a modular and extensible fashion,
while also maintaining the highest possible performance on modern
GPUs and graphics APIs. Slang is based on years of collaboration
between researchers at NVIDIA, Carnegie Mellon University, Stanford,
MIT, UCSD and the University of Washington.

The Slang compiler can generate code for a wide variety of targets:
D3D12, Vulkan, Metal, D3D11, CUDA, and even generate code to run
on a CPU. For textual targets, such as Metal Shading Language (MSL)
and CUDA, Slang produces readable code that preserves original
identifier names, as well as the type and call structure, making
it easier to debug.
