CAB-MPI: Exploring Interprocess Work-Stealing toward Balanced MPI Communication

Argonne researchers co-authored a paper that introduces CAB-MPI, an implementation of Message Passing Interface (MPI), as a tool for designing communication-balanced applications. Leveraging a work-stealing scheme based on process-memory-sharing techniques, CAB-MPI can identify and use idle MPI processes to dynamically balance the communication workload of an application.
