CUDA C kernels directly to SPIR-V #25

Open klwin523 opened 2 years ago

klwin523 commented 2 years ago

The notes say: VUDA does not provide any support for compiling CUDA C kernels directly to SPIR-V (yet) Is there a roadmap or technical approach you're planning to support that? Maybe we can help implement that based on what you already have in mind.

Hi and thanks for posting.

The notes are referring to the general state of existing compilers, e.g. GLSL to SPIR-V, HLSL to SPIR-V, and prototypes for Rust to SPIR-V or OpenCL C to SPIR-V.

That said, it would of course be very useful and beneficial to have support for something like that. However, it is somewhat of an undertaking to develop and support a full CUDA C to SPIR-V compiler (not to mention CUDA C++).

From VUDA's point of view, only some very preliminary development has been done - building on LLVM, and I greatly encourage anyone to put work into such a project.

There's a project that does something similar: https://github.com/seanbaxter/shaders
