ProActive is a Java library (Source code under GPL license) for parallel, distributed, and concurrent computing, also featuring mobility and security in a uniform framework. ProActive aimed at simplifying the programming of applications that are distributed on Local Area Network (LAN), on cluster of workstations, or large scale Grids. ProActive promotes a strong NoC approach, Network On Ship, to cope seamlessly with both distributed and shared-memory multi-core machines. A theoretical foundation ensures constant behavior, whatever the environment.ProActive features location tracking of moving objects, together with a strong programming model that makes it very suitable for global computinginfrastructure.Interactive and graphical GUI of the ProActive Parallel Suite will also be presented during the talk.
