    The new Process Execution Engine offered by the gCube platform consumes, manages and expose computational resources offered by the native gCube platform, underlying Grid infrastructure as well as external Cloud infrastructures. The computation providers span a large technological range including Web Services of several paradigms (REST-WS, SOAP-WS, WSRF), technology specific binaries or script executables.

    Facilitating the exploitation and hiding the complexities, the Process Execution Engine constitutes a mechanism capable of orchestrating flows of invocations on this large and diverse set of targets over a multitude of enabling infrastructures.

    The overall objective is one of bridging the gCube with heterogeneous platforms such as the underlying EGEE gLite Grid , the Condor, the Hadoop and more. By employing an architecture that involves a number of abstractions (infrastructure adapters and storage providers)  and  a number of standards such as JSDL for the specifications of the operations, the Process Execution Engine can serve effectively its cause.

    INSPIRE - PE2ng interoperation

    One of the interoperability cases the gCube platform targets in the context of D4Science-II is that of interoperating and providing computational abstractions and resources to the Invenio software on top of which the INSPIRE community offers its services. This is also one of the most extensive and broad spanning cases the Process Execution capacities are exercised.

    INSPIRE and D4Science-II related abstract has been accepted for the CHEP2010 conference.

    Computing in High Energy and Nuclear Physics (CHEP) conference will be  held at Academia Sinica in Taipei 18-22 October 2010. For more information about the conference, please click here.

    Physicists get INSPIREd: INSPIRE Project and Grid Applications

    INSPIRE is the new high-energy physics scientific information system developed by CERN, DESY, Fermilab and SLAC. INSPIRE combines the curated and trusted contents of SPIRES database with the Invenio digital library technology. INSPIRE contains the entire HEP literature with about one million records and in addition to becoming the reference HEP scientific information platform it aims to provide new kinds of data mining services and metrics to assess the impact of articles and authors.

    Grid and cloud computing provide new opportunities to provide better services in areas that require large CPU and storage resources including document Optical Character Recognition (OCR) processing, full-text indexing of articles and improved metrics.

    D4Science-II is a European project that develops and operates an e-Infrastructure supporting Virtual Research Environments (VREs). It develops an enabling technology (gCube) that implements mechanism for facilitating the interoperation of its e-Infrastructure with other data e-Infrastructures that are running autonomously thus creating the core of  an e-Infrastructure Ecosystem. INSPIRE is one of the e-Infrastructures participating in D4Science-II project. In the context of the D4Science-II project, the INSPIRE e-Infrastructure will make available some of its resources and services to other members of the resulting Ecosystem. Moreover, it will benefit from Ecosystem via a dedicated VRE giving access to an array of resources ranging from computingand storage resources of grid infrastructures to data and services.

    A new release of the gCube software is now available. It is the version 1.8.0 and it includes important novelties.

    Among the innovations introduced by this release, graphically appealing can be emphasized with the GIS viewer, that allows to visualize species distribution maps.
    The images show the distribution of dangerous species.  The first one with the earth globes represents the plain images as they were generated before release 1.8.0. The other two are screenshots of the new GIS viewer.

    Final D4Science review report has been rated as 'excellent'. This evaluation received by a panel of international experts said:
    “D4Science achievements in advancing gCube technology are very useful, and should not stay limited to the original target community. The technology may be used in a much wider scale independently of the specific applications covered by D4Science. The reviewers recommend increasing visibility of project results on the international level by all possible means.”

    The 25 May D4Science-II Members General Assembly took place in Rome, Italy, with the presence of: Andrea Manieri, E-IIS, Donatella Castelli, CNR, Pasquale Pagano, CNR, Fabio Simeoni (representing US on behalf of Richard Connor), Fabrice Brito (representing Terradue on behalf of Pedro Gonçalves), Jessica Michel, ERCIM, Marc Taconet, FAO, Tim Smith, CERN.

    Following the agenda, the Members voted to add two representatives to the PMB to include presence of the communities, one loosely referred to as “Biodiversity Scenarios” and the other as “Digital Libraries”. This consultation was accepted as well as the actual representatives, that will be the following: Marc Taconet with Johannes Keizer or Anton Ellenbroek as Deputy for FAO, and Tim Smith or Salvatore Mele for CERN.

    The minutes of the meeting can be found on the BSCW

    The European Conference on Research and Advanced Technology for Digital Libraries (ECDL) is inviting authors to submit papers for the workshop Making Digital Libraries Interoperable, that will take plece 9-10 September 2010, during ECDL2010 in Glasgow, Scotland, UK.

    ECDL is the leading European scientific forum on digital libraries and associated technical, practical, and social issues. It brings together researchers, developers, content providers and users in the field. ECDL 2010, the 14th conference in this series, organised by the University of Glasgow will take place on September 6-10,

    The D4science II project was represented at the 5th EGEE User Forum meeting held from 12-16 april by the Uppsala University(Sweden).

    1. Building Scientific Workflows for the Fisheries and Aquaculture Management Community based on Virtual Research Environments was presented by Pedro Andrade (CERN).
      The management of resources related to the Fisheries and Aquaculture (FARM) domain is complex and involves different scientific activities. The people involved in the domain are distributed worldwide: scientists in the field, regional statistics departments, national governing bodies, etc. Distributed information must be produced, analyzed, processed, shared, and preserved by all multiple actors through a number of scientific workflows. The D4Science-II project provides a number of Virtual Research Environments (VREs) to address the collaboration needs of this community.
    2. Pros and Cons of cloud adoption in the Scientific Data Infrastructures - the D4S-II case was presented by Andrea Manieri (Engineering Ingegneria Informatica S.p.A.)
      The D4Science-II project provides as major product the gCube middleware. It is a grid-enabled service oriented middleware enabling the creation and operation of Virtual Research Environments, to serve the management and exploitation of scientific data. As part of the D4Science-II project a study on the impact of cloud technology (mainly Virtualisation) and cloud capabilities (on-demand availability and scalability) on the gCube software will be performed. The study will also analyse the impact of cloud technology from a commercial point of view (market positioning, possible exploitation strategies).
