Checkpoint/Restart (C/R) is a widely used fault tolerance mechanism in converged systems
of cloud, edge, and HPC. However, users often rely on their experience to determine which …

Collective communication operations, such as Broadcast or Reduce, are fundamental
cornerstones in many high-performance applications. Most collective operations can be …

We explore the use of a regular, circulant graph communication pattern for the
implementation of the reduction-to-all (MPI_Allreduce), by specialization the reduction-to …

High-performance computing (HPC) mesh generation codes are often optimized while
intertwining functionality with performance aspects of code, making these methods highly …

Exascale supercomputers have renewed the exigence of improving distributed
communication, specifically MPI collectives. Previous works accelerated collectives for …

Performance benchmarks are an integral part of the development and evaluation of parallel
algorithms, both in distributed applications as well as MPI implementations themselves. The …
