Usable computing on open distributed systems

ABSTRACT

An open distributed system provides a best-effort guarantee on the quality of service provided to applications. This has worked well for throughput-based applications of the kind typically executed in Condor or BOINCstyle environments. For other applications, the absence of timeliness of correctness guarantees limit the utility or appeal of this environment. Computational results that are too late or erroneous are not usable to the application. We present techniques designed to efficiently promote usable computing in open distributed systems.
