Java']Java application execution in heterogeneous and multi-user systems

This article presents an inter-application load balancing mechanism meant to improve the efficiency of execution for Java parallel and distributed applications in a network of workstations. One difficulty of such architectures is dealing with heterogeneity: workstations have different powers and operating systems. Moreover, the workstations are generally executing several processes, corresponding to an external load, outside the JVM, as in the case of multi-user systems. Consequently, heterogeneity and resource sharing are features included in the design of the dynamic load balancing in ADAJ. Two new Java tools; of calibration and of load measure, are proposed and used to extend the previously load balancing approach applicable on a dedicated and homogeneous environment.
