Supporting Compiled Communication on Commodity Networks

点击翻译按钮获取中文摘要

This project investigates the compiled communication technique on commodity networks. In compiled communication, high performance communication is achieved by using the compiler to analyze the communication requirement of a program and to manage network resources statically to support the communications. As a result, runtime communication overheads, such as buffer management, are reduced and/or amortized over a number of communications, and the communication performance is improved. Compiledcommunication is more powerful than traditional communication optimization techniques in that it performs communication optimizations in both thecompiler and the hardware/operating system/runtime system. The outcomeof the proposed research is an extension of the MPI library that supportsthe compiled communication model, a SUIF based restructure compiler that can generate communication code using the compiled communication model,an experimental demonstration of how much performance improvement can beachieved by using the compiled communication model, and a clear identification of the advantages and limitations of the compiled communicationmodel.
