Communication delegation method for exascale systems
Yugendra R. Guvvala, Yu Zhuang · 2014
High Performance Computing is trending towards exascale and some of the major barriers of high performance computing or scientific computing are dominated by latencies incurred due to storage, communication, and component failures. In this paper we discuss a technique to overcome one of those obstacles: latency incurred due to communication. This programming technique is developed using existing MPI and OpenMP communication models and the technique discussed in this paper is Communication Delegation Method, which will provide an efficient way of communicating across nodes and reducing communication channel resource contention.
