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. 

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

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)

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)

8
WWU Muenster

• HOC-SA (http//pvs.uni-muenster.de/pvs/forschung/h
  oc/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

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

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

11
