  4. Current activities • Answer to e-mail sent the 9th of June 2006 • «  mention any research activity (not necessarily joint activity) related to WP3.1 which is in progress or is just finished in the CoreGRID NoE. » 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 European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies

  6. INRIA (Shopia Antipolis) • ProActive (www.objectweb.org/proactive) • Asynchronous calls: typed messages (request and reply) • Automatic future-based synchronizations : wait-by-necessity • Remote creation of remote objects • Distributed and non-functional exceptions handling • Transparent, dynamic code loading (up and down) • Reuse: polymorphism between standard objects and remote objects • Group communications with dynamic group management • grounding parallel or distributed programming patterns such as • Object Oriented SPMD • Mobile agents • structured parallelism (aka skeletons) European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies

  7. UNIPI • ASSIST (http://www.di.unipi.it/Assist.html) • Parallel programming with skeletons • Coordination language to describe the skeleton of distributed programs • Statically connected “parallel modules” • Parallel Module • Farm, Pipeline, Geometric pattern, Data parallelism • Tools • Compiler (C++, Fortran) generates binaries for multiple platforms • Configuration files (application description) • Deployable tarball (XML config) European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies

  8. WWU Muenster • HOC-SA (http://pvs.uni-muenster.de/pvs/forschung/hoc/index-en.html) • HOC-SA: components (HOCs) for recurring patterns of parallel behavior as Web services • Central elements: Code Service and Custom Code Loader • Programming concept: application-specific code is provided as a parameter inserted into generic code which is readily deployed to the Grid servers (similar to skeletal programming, but component-based, i.e., HOCs include the required middleware configuration) • Purpose: simplify grid programming by abstracting over the middleware • Reference implementation based on Globus Toolkit 4 European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies

  9. VUA • Ibis (http://www.cs.vu.nl/ibis/) • a Java-based Grid application programming environment providing object-based communication models: RMI, GMI, RepMI, Satin (divide-and-conquer) and MPJ • GAT (https://forge.gridforum.org/projects/saga-rg/) • simple and standardized APIs to Grid resources and middleware European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies

  10. HES-SO/EIA-FR • POP-C++ (www.eif.ch/gridgroup/popc) • a minimal extension of the C++ programming language implementing the notion of “parallel object”. • a parallel object is a object which can be instantiate on a remote computer • communication between can be done using six different semantics for remote procedure calls • integrates support for resource management and resource discovery European Research Network on Foundations, Software Infrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies

  11.
