gCUBE / Framework

gCube is a framework dedicated to scientists. It enables the declarative and interactive
creation of transient Virtual Research Environments that aggregate and deploy on-demand
content resources and application services by exploiting computational and storage
resources of a grid infrastructure.

Overview

gCube Overview

gCube system is a Software Platform for the implementation and servicing of Virtual Research Environments (VRE) based on the Service Oriented Paradigm and a number of specifications and technologies that relate to the technological and functional areas addressed by its core services.

gCube system is Open Source Software and the base technologies that underly its development are

Java
WS Core (WSRF Implementation of Globus Toolkit 4 )
gLite EGEE's grid enabling middleware
GridSphere Portal Framework for the provision of end-user and administrative interfaces

gCube system not only provides a complete set of services to support the instantiation of VREs, but also provides a set of sub-frameworks for the adaptation and expansion of its services and capabilities, so that the provided features can match the requirements of a particular scientific application domain.

Success Stories

The gCube software is installed in an e-Infrastructure operated by the D4Science project, and its successor the D4Science-II project. The D4Science e-Infrastructure builds upon the EGEE gLite-based grid and is powered by the gCube system.

The D4Science e-Infrastructure spans across 7 sites in 3 countries. It counts about 100 nodes and 850 TB of storage, contributed by 5 partner entities. The D4Science e-Infrastructure serves today almost 200 users, belonging to 2 communities of users.

What does the D4Science e-Infrastructure offer?

By operating the gCube software, the D4Science e-Infrastructure offers to its user communities coordinated and secure sharing of computing and storage resources, as well as software tools, services and data repositories. It allows specific scientific research groups inside the user communities cost-effective, scalable and highly-configurable set up of multi-disciplinary Virtual Research Environments (VREs) for the generation and dissemination of scientific and technical knowledge.

The D4Science e-Infrastructure interfaces and uses the computational and storage capabilities offered by the grid operated by the EGEE project (www.eu-egee.org). In this way, it delivers a data infrastructure for the generation, curation, representation, and management of large data sets.

3rd Technical Committee (TCom)
Paros, Greece, 15-18 June 2010
The 3rd Technical Committee (TCom) meeting took place between the 15-18 of June 2010 in Paros, Greece. The meeting was organised by National and Kapodistrian University of Athens (NKUA) at the Porto Paros Hotel in Paros.


5th EGEE User Forum
12-16 April 2010, Uppsala University
The 5th EGEE User Forum was held in collaboration with EGI and NDGF in Uppsala, Sweden, April 12-16, 2010. With the establishment of sustainable European and National e-Infrastructures this event was the ideal place for European e-Infrastructure users to meet, share experiences, and shape the future of European e-Infrastructures. The D4science II project was represented at the 5th User Forum meeting held from 12-16 april by the Uppsala University( Sweden).


The D4Science Approach Toward Grid Resource Sharing: the Species Occurrence Maps Generation Case
Taipei, Taiwan, 8-12 March 2010
The D4Science e-Infrastructure is a framework enabling secure, cost-effective and on-demand resource sharing across organisation boundaries. Powered by gCube, the D4Science e-Infrastructure lifts the grid-paradigm at an application-level and poses as a “mediator” in a market of resources aiming to accommodate the needs of resource providers and consumers. This potentially not-limited market allows a new development paradigm based on the notion of Virtual Research Environment (VRE), i.e. integrated environment providing seamless access to the needed resources as well as facilities for communication, collaboration and any kind of interaction among scientists and researchers. To showcase these capabilities the AquaMaps VRE has been presented at the Internationl Symposium on Grid Computing (ISGC).
