JECho-interactive high performance computing with Java event channels

This paper presents JECho, a Java-based communication infrastructure for collaborative high performance applications. JECho implements a publish/subscribe communication paradigm, permitting distributed concurrent sets of components to provide interactive service to collaborating end users via event channels. JECho´s eager handler concept allows individual event subscribers to dynamically tailor event flows to adapt to runtime changes in component behaviors and needs, and to changes in platform resources. Benchmark results suggest that JECho may be used for building large-scale, high-performance event delivery systems which can efficiently adapt to changes in user needs or the environment using eager handlers
