Which CloverLeaf OMP Target repo to use?

[jhdavis8]

I notice there are two OpenMP target implementations of CloverLeaf available:

https://github.com/UoB-HPC/cloverleaf_openmp_target (this one)

and

https://github.com/UoB-HPC/CloverLeaf-OpenMP4

What are the differences and which is the most up-to-date? In general, is https://github.com/UK-MAC/CloverLeaf the authoritative source for all CloverLeaf variants?

https://github.com/UK-MAC/CloverLeaf contains mostly Fortran implementations and some of the models are a bit out of date as compiler support and standard have moved on (OpenMP offload, for example).
This repo, along with the following repos:

• https://github.com/UoB-HPC/cloverleaf_sycl/
• https://github.com/UoB-HPC/cloverleaf_kokkos/
• https://github.com/UoB-HPC/cloverleaf_stdpar/
• https://github.com/UoB-HPC/cloverleaf_openmp_target/
• https://github.com/UoB-HPC/cloverleaf_HIP/
• https://github.com/UoB-HPC/cloverleaf_tbb

all contain more up-to-date ports, but MPI paths > 1 rank is known to fail and each repo has a different build setup.
The good news is, all of the above will be superseded by a unified driver with a working MPI implementation soon.
Once that happens, we'll archive and put a notice on all the distinct repos listed.

I'll put a link here when the new driver is ready.
@tomdeakin how does this sound?
