5. European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies 5 INRIA (Rennes) PaCO++ (http://www.irisa.fr/paris/Paco++/) –implementation of the notion of “collective entities” in CORBA –a parallel entity is a collection of identical objects –allow a simple and efficient embedding of a SPMD code into a parallel CORBA object –provides portable parallel CORBA objects on top of compliant ORB without involving whatsoever modification of the CORBA specifications –extends CORBA but not to modify the model
