Using Effective Network Views to Promote Distributed Application Performance.
Gary Shao, Francine Berman, Richard Wolski · 1999
Abstract In this paper, we show that distributed parallel application performance in clusters of workstations benefits from knowledge about network topology in cases where LAN resources can become potential performance bottlenecks. These performance bottlenecks often appear in common networking technologies that employ highly shared resources, such as ethernets and token-rings. A method to discover network configuration as it relates to application performance, called Effective Network Views (ENV), is presented, and experimental results with an example application are given to show the value of including ENV information in the scheduling process when good performance is required.
