I don't know what we do to create new working groups with the post-COVID rules, but I would like to create and chair a WG focused on ABI standardization.
There is strong support for this effort in many user communities, including developers and maintainers of Spack, mpi4py, Julia MPI (MPI.jl), Rust MPI (rsmpi), PETSc and NVHPC SDK, to name a few. There are even a few implementers who have expressed support, but I won't name them for their own protection. The problem is so exasperating for our users that there are at least two different projects devoted to mitigating ABI problems (not including shims built in to the aforementioned MPI wrappers): https://github.com/cea-hpc/wi4mpi https://github.com/eschnett/MPItrampoline I've written about this a bit already, for those who are interested. More material will be forthcoming once I have time for more experiments. https://github.com/jeffhammond/blog/blob/main/MPI_Needs_ABI.md https://github.com/jeffhammond/blog/blob/main/MPI_Needs_ABI_Part_2.md https://github.com/jeffhammond/blog/blob/main/MPI_Needs_ABI_Part_3.md https://github.com/jeffhammond/blog/blob/main/MPI_Needs_ABI_Part_4.md I understand this is a controversial topic, particularly for implementers. I hope that we can proceed objectively. Thanks, Jeff -- Jeff Hammond jeff.scie...@gmail.com http://jeffhammond.github.io/
