Desynchronization and Wave Pattern Formation in MPI-Parallel and Hybrid Memory-Bound Programs
Analytic, first-principles performance modeling of distributed-memory parallel codes is notoriously imprecise. Even for applications with extremely regular and homogeneous compute-communicate phases, simply adding communication time to computation time does often not yield a satisfactory prediction...
