Persistent and Partitioned MPI for Stencil Communication
Gerald Collom, Jason Burmark, Olga Pearce +1
Many parallel applications rely on iterative stencil operations, whose performance are dominated by communication costs at large scales. Several MPI optimizations, such as persiste…

Optimizing Irregular Communication with Neighborhood Collectives and Locality-Aware Parallelism
Gerald Collom, Rui Peng Li, Amanda Bienz
Irregular communication often limits both the performance and scalability of parallel applications. Typically, applications individually implement irregular messages using point-to…
