Deprecation warnings with cuSPARSE 11.8

[lahwaacz]

Building ginkgo with CUDA 11.8 results in many warnings, mostly deprecation warnings from cuSPARSE. I'm attaching a complete build log of the ginkgo-hpc-git AUR package.

ginkgo-hpc-git-r5521.8b036c64f4-1-x86_64-build.log

Thanks for the report! We should add some version compile guards here (mirroring the ones in common_trs_kernels.cuh for csrsm*). Does AUR have a mechanism to compile for specific hardware? SM 3.5 is only being enabled if no GPU is detected at all. You might want to list a set of GPU architectures explicitly (increasing compile time and binary size) or find some other way to make it configurable

[lahwaacz]

I'm explicitly setting -DGINKGO_CUDA_ARCHITECTURES="All" because the built package should be usable on any hardware. But the AUR contains just the PKGBUILD, not the binary package itself.

In that case, I would suggest listing the non-deprecated SMs instead of All to avoid these warnings

[lahwaacz]

I could also add the -Wno-deprecated-gpu-targets flag to avoid the warnings.

That sounds like the best course of action. I'll add the missing compiler guards to deal with the deprecated functionality.
