Replication in OpenMPI (Middleware)

Conducted by

Description

The goal is to evaluate an implementation of replication in OpenMPI at large scale. The evaluated applications are the NAS Parallel Benchmarks and few real HPC applications (not decided yet). We mesure : - The replication protocol overhead. - The impact of buffering instead of synchronization
