I’m in the process of implementing asynchronous GPU support for petsc. A side effect of this is that I unify the cuda/hip interface such that anywhere we have cuda-like code we will automatically also get the hip variant.
The scaffolding is in include/petsc/private/cupminterface.hpp, but for concrete examples see the jacobf/2021-10-21/veccupm-async branch for the WIP port of VecSeq in src/vec/vec/impls/seq/seqcupm/veccupm.hpp. Best regards, Jacob Faibussowitsch (Jacob Fai - booss - oh - vitch) > On Nov 10, 2021, at 11:50, Justin Chang <jychan...@gmail.com> wrote: > > Paul Bauman was also involved with the HIP port of HYPRE.
