Distributed and Parallel Computing Systems

We present Xipx , the first port of a major educational operating system to a processor in the emerging class of many-core architectures. Through extensions to the proven Embedded Xinu operating system, Xipx gives students hands-on experience with system programming in a distributed message-passing environment. We expose the software primitives needed to maintain coherency between many cores in a system lacking specialized caching hardware. Our proposed series of laboratory assignments adds parallel thread execution and intercore message passing communication to a well-established OS curriculum.
