This commits adds cmake functionality that can
hipify the cuistl framework to support AMD GPUs.
Some tests have been written as HIP does not mirror
CUDA exactly.
CONVERT_CUDA_TO_HIP is the new CMAKE argument.
CMAKE version is increased to include HIP
as a language (3.21 required).
A macro is added to create a layer of indirection
that will make only cuistl files that have been
changed rehipified.
Some BDA stuff is extracted to make sure CUDA
is not accidentally included.
We got compile errors like:
/home/build/opm-simulators/opm/simulators/linalg/FlexibleSolver1.cpp:24:1: required from here
/usr/include/dune/istl/ilu.hh:140:29: error: 'double' is not a class, struct, or union type
without this patch.
Hence we use the new internal ILU functions if available.
Previously, the user had to specify it in the json file read from the
FlexibleSolver or 1 was used. Unfortunately, the index depends on the
model used and it seem rather opaque to a user what that index is.
With this commit we determine the pressure index from the model.
