Towards Safe HPC: Productivity and Performance via Rust Interfaces for a Distribu...
summary
Proof-of-concept Rust interface wraps an existing distributed C++ actors library (HC lib) and the conveyors message layer, exposing a safe selector API that hides unsafe pointer fiddling. Four Bale-kernel actor apps are ported with static bug catches and a large reduction in unsafe lines. Runtime stays within C++ performance for three benchmarks; one (random permutation) shows a spike at 2048 PEs. Circular references and C++-style inheritance are resolved by dependency inversion and API restructuring.
