Support for Reliable Distributed Computing

Abstract

This technical report consists of two papers describing support for reliable distributed computing. Data Path Debugging: Data-Oriented Debugging for a Concurrent Programming Language explains our goal of data-oriented debugging, and then presents Data Path Expression (DPE) debugging, our approach to data-oriented debugging for concurrent programming languages. DPE is being implemented as pan of MD, the MELD Debugger. A Network Architecture for Reliable Distributed Computing proposes a reliable distributed environment (RDE) based on an efficient and reliable extension to datagram communications. It gives simulation results for coupled relations based on different algorithms， node failure rate, recover rate, message sending rate and data missing rate, and to illustrate behavior of distributed systems constructed using our view section model on top of RDE
