Hierarchical Matrix-Matrix Multiplication Based on Multiprocessor Tasks

Abstract

We consider the realization of matrix-matrix multiplication and propose a hierarchical algorithm implemented in a task-parallel way using multiprocessor tasks on distributed memory. The algorithm has been designed to minimize the communication overhead while showing large locality of memory references. The task-parallel realization makes the algorithm… (More)
