Pattern-Based Systematic Task Mapping for Many-Core Processors

Abstract

The Network-on-Chip (NoC) is a promising interconnection for many-core processors. On the NoC-based manycore processors, the network performance of multi-thread programs depends on the method of task mapping. In this paper, we propose a pattern-based task mapping method in order to improve the performance of many-core processors. Evaluation of the proposed method using a detailed software simulator reveals an average performance improvement of at least 4.4%, as compared with standard task mapping using NAS parallel benchmarks.
