ferrompi

experimental

Safe MPI 4.x bindings for Rust, used by cobre-comm as the MPI communication backend. This is a separate repository at github.com/cobre-rs/ferrompi.

ferrompi provides type-safe wrappers around MPI collective operations (allgatherv, allreduce, broadcast, barrier) with RAII-managed MPI_Init_thread / MPI_Finalize lifecycle. It supports ThreadLevel::Funneled initialization, which matches the Cobre execution model where only the main thread issues MPI calls.

See the ferrompi README and the backend specification for details.
