| Beschreibung: | In this paper we present a platform, ADAJ (Adaptive Distributed Applications in Java), that we have developed for distributed applications in Java over a cluster of computers. The objective of this platform is to facilitate the application design and to efficiently use the computing power. ADAJ offers both a programming and execution environment. The programming environment simplifies the user programming effort and offers a MIMD/SPMD programming model style. Our approach relies on the concept of distributed collections, grouping fragmented objects and on asynchronous calls. The ADAJ execution environment supports irregularities during the evolution of the application and in the availabilities of resources. We present the architecture and the tools we have developed: object observation and load balancing mechanisms. The observation mechanism allows to estimate the JVM load. The load balancing mechanism dynamically adapts the execution according to this information. We present estimation measures on two different applications, so that to evaluate the benefits and the overhead of ADAJ. |
