ZLUDA Project Paves the Way for CUDA on Intel

"The result showed that ZLUDA's performance was up to 10% faster in comparison to OpenCL performance. Overall, we're looking at around a 4% uplift from the set of benchmarks.

The author made it clear that ZLUDA is completely dissimilar to AMD HIP or Intel DPC++ in the sense that the latter two are tools for programmers to port applications to the the specific API of choice. ZLUDA, on the other hand, doesn't require any extra effort since CUDA applications simply work on an Intel GPU — as long as the CUDA subset is supported, of course.

In its current state, ZLUDA is only compatible with Intel Gen9 iGPUs (Skylake through Comet Lake), but there is planned support for the chipmaker's upcoming Xe GPUs as well. ZLUDA doesn't support AMD GPUs, however, the author delved into the idea that it should be technically possible to do so. Nvidia might not be too happy with the idea, but others surely will be."
