PROBLEM
MSMPI has no native ARM64 Windows support — no ARM64 build targets, no platform guards, x64/x86 binaries only. This blocks MPI-dependent workloads on WoA hardware.
WHY IT MATTERS
ARM64 Windows adoption is accelerating (Snapdragon X Elite, Surface, cloud-on-ARM). Native execution eliminates x64-emulation overhead, which is material for compute-bound MPI workloads.
CURRENT STATUS
Our fork is based on Linaro's WOA implemantation and has been tested on a physical ARM64 Windows machine against various workload like MFEM, LAAMPS.
INTENT
I plan to submit a PR for WoA once confirmed.
