Delegation-Based MPI Communications for a Hybrid Parallel Computer with Many-Core Architectureny-core CPUs but also multi-core ones by deploying multi-layered MPI communicator information. Here we evaluated the delegation mechanism on an emulated hybrid computing environment. We show our innovative design and its performance evaluation on the emulated environment in this paper.

Micro-applications for Communication Data Access Patterns and MPI Datatypesificant performance discrepancies between state-of-the-art MPI implementations. Our micro-applications aim to provide a standard benchmark for MPI datatype implementations to guide optimizations similarly to SPEC CPU and the Livermore loops do for compiler optimizations.
