THEORY A Theory of Distributed Objects D. Caromel, L. Henrio, Springer 2005, Monograph A Calculus: ASP: Asynchronous Sequential Processes • Based on Sigma-Calculus (Abadi-Cardelli) • Formal Proofs of determinism • Releases a few important implementation constraints Denis Caromel 8

ProActive : Active objects A ag = newActive (“A”, […], VirtualNode) V v1 = ag.foo (param); V v2 = ag.bar (param); ... v1.bar(); //Wait-By-Necessity JVM JVM A ag v2 v1 A WBN! V Wait-By-Necessity Req. Queue is a Java Object Active Object Dataflow Thread Request Future Object Proxy Synchronization 10 Denis Caromel 10

Creating AO and Groups A ag = newActiveGroup (“A”, […], VirtualNode) V v = ag.foo(param); ... v.bar(); //Wait-by-necessity JVM A V Group, Type, and Asynchrony ����������� ��������������������� are crucial for Cpt. and GRID 11 Denis Caromel 11

Conclusions and A Few Directions A Strong Programming Model + Components + Env ProActive : NOT discussed so far: Web Service, FT, Exceptions FACTS AND FIGURES 53 years of computation in 6 months in Desktop P2P Deployed at once on 2111 CPUs (PLUGTESTS on ssh, Globus, LSF, ...) (Close to) Beating Fortran on an Electromagnetic Application PERSPECTIVES: Behavior Specification, Fully Integrated Debugger A great alchemy for the Grid + SOA: Asynchrony + Wait By Necessity + Groups + Components Denis Caromel 28
