Title
Delegation-Based MPI communications for a hybrid parallel computer with many-core architecture
Abstract
Many-core architecture draws much attention in HPC community towards the Exascale era. Many ongoing research activities using GPU or the Many Integrated Core (MIC) architecture from Intel exist worldwide. Many-core CPUs have a great deal of impact to improve computing performance, however, they are not favorable for heavy communications and I/Os which are essential for MPI operations in general. We have been focusing on the MIC architecture as many-core CPUs to realize a hybrid parallel computer in conjunction with multi-core CPUs. We propose a delegation mechanism for scalable MPI communications issued on many-core CPUs so as to play delegated operations on multi-core ones. This architecture also minimizes memory utilization of not only many-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.
