"me too". Debian's GPU support is in general somewhat underdone, partly
due to cuda's historical nonfreeness.
Improving our GPU support is a good theme for a GSOC project.
Hypre has some GPU support, good to improve and test its activation. I
think PETSc might have some too.
If we get it running well, we'll start wanting to have debci GPU testing
too to be sure it continues to work. Might be possible to build upon my
GSOC project last year with Nikolaos Chatzikonstantinou for that step,
though good also if debian's own CI infrastructure can cover GPU.

Just to add:
I’ve added HIP/ROCm support to mpich 4.3.0 in experimental, (Its present in UCX so OpenMPI uses this); I’m working on enabling it on atlas-ecmwf (just working on one known. Bug),
and am finalizing packaging of UCC – Unified Collectives Communication, which adds GPU (HIP) collectives support to UCX for MPI etc.
