CUDA cooperative_groups is not supported

Hi all

 

I use dpct to convert a CUDA sample program: convolutionSeparable

But the dpct shows "warning: DPCT1007:17: Migration of this CUDA API is not suppor
ted by the Intel(R) DPC++ Compatibility Tool."

And dpcpp cannot compile the generated cpp file, and throw an error "use of undeclared identifier 'cg'"

What would you suggest to the cooperative_groups in OneAPI?

Thanks

Currently DPC++ doesn't have a equivalent of cooperative groups in CUDA. There is a feature request requested for the same.
