User Level Communication on Alpha Linux Systems

User Level Communication on Alpha Linux Systems
Recent advances in commodity network interface technology enable scientists and engineers to build clusters of workstations or PCs to execute parallel applications. However, raw-hardware network performance is rarely delivered to applications because of the overheads of communication software and operating systems. To reduce these overheads, a technique called user-level communication can be used to allow applications to access the network interface directly without intervention from the operating system. In this paper we examine two user-level communication systems,GM and BIP, on alpha based systems connected by a Myrinet network. In addition quantitative studies on how DMA initiation costs, flow control and reliable communication will effect the performance of communication software are presented.
