SUMMARY:Embedding Rust within Open MPI
DESCRIPTION:Jake Tronge and Howard Pritchard (Los Alamos National Laborato
 ry (LANL))\n\nThe Message-Passing Interface (MPI) requires implementations
  that are able to adapt to new hardware and architectures while ensuring c
 orrectness and usability. The most widely used MPI implementations, howeve
 r, are written in older programming languages that can lead to memory-unsa
 fe code with poor isolation between modules, and complicated interfaces th
 at can lead to serious bugs, all of which leads to difficulty in testing, 
 debugging, and checking for correctness. In order to improve development o
 f MPI implementations, we posit that new components, and key existing code
  segments, may benefit from being written in the Rust programming language
 . In this work, we re-implement a core component of Open MPI used for intr
 a-node communication in Rust and show that it achieves performance approac
 hing that of the existing, highly optimized, C code, demonstrating that Ru
 st is able to provide performance while allowing for better testing, memor
 y safety guarantees, and correctness.\n\nTag: Exascale, Message Passing, P
