Designing communication strategies for heterogeneous parallel systems

摘要

This paper explores the suitability of the emerging passive star-coupled optical intercon- nection using wavelength division multiplexing as the system interconnect to provide high bandwidth(Gbits/sec)communication demanded by heterogeneous systems. several different communication strategies(combinations of communication topologies and protocols)are investigated under a representative master-slave computational model. The interplay between system speed, network speed, task granularity, and degree of parallelism is studied using both analytical modeling and simulations.
