14. High-Performance Distributed Computing Ibis: a Java-centric grid programming environment oRemote Method Invocation (RMI), group communication, divide&conquer parallelism, object migration (ProActive) Written in pure Java, runs on heterogeneous grids o“Write once, run everywhere ” oUse bytecode rewriting for optimizations (e.g. serialization) oUse native code as special-case optimization (e.g. Myrinet)

15. Experiences with Ibis Distributed supercomputing applications oElectromagnetic simulation (Jem3D) oAutomated protein identification (AMOLF) oN-body simulations, SAT-solver, raytracer Successful grid experiments oOn DAS-2 (homogeneous Dutch grid) oOn GridLab (European grid) Need co-allocation mechanisms More info + distribution at www.cs.vu.nl/ibis
