「Explicit SIMD programming support inside parallel_for kernel through extension sycl::intel::gpu::simd template.」

　Please tell me how to use it.

Hi,

We have checked the GitHub repository which you have provided, as per the README.md file, I assume that this feature is not supported for Windows target yet.

https://github.com/intel/llvm/blob/sycl/sycl/doc/extensions/ExplicitSIMD/README.md

However, to confirm, we are talking with the concerned internal team regarding this. We will get back to you soon.

Thanks & Regards

Thank you for your answer.

Even if windows target wasn't supported yet,

I hope this function will be available on windows in a future update.

best regard.
