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

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)

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

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
