Virtual Research Communities

Virtual Research Communities (VRCs) are like-minded individuals grouped together by discipline or computational model. VRCs typically have an established presence in their field (for example an ESFRI project, EIROFORUM laboratory or national research structure) and represent a specific its scientific or other research community.

The Role of A&A VRC

The Astronomy and Astrophysics VRC is the lightweight coordination for astronomers and astronomical projects that want to use the EGI e-Infrastructure.

In particular our activity is to support the A&A community and to provide an interface to EGI general services (Training and dissemination, operation, and so on).

We also actively work on service development and implementation in particular:

  • visualization tools. VisIVO is a suite of software tools aimed at creating customized views of 3D renderings from many type of dataset. Their peculiar characteristic is that there is no limit for what concerns the size of input tables containing data to be processed, thus they are able to support very large scale datasets (tens of Terabytes and more). VisIVO can be easily used to visualize and monitor data simultaneously, as they are produced by the jobs running on the grid; data under production can also be used to create movies. VisIVO has been integrated with the Grid resources and in particular with the data management service in order to visualize data stored on the Grid.
  • Data and metadata management. Interactions and interoperability aspects between Grid infrastructures and databases are one of the hot topics for A&A applications. The main goal of this activity aims at evaluating the current state of the art of database integration in the Grid; the tools currently in production (OGSA-DAI, Spitfire, GRelC, AMGA) will be analyzed to understand the effort requested to adapt them to A&A applications.
  • Use of GPU and HPC resources. A&A VRC participates at the EGI-Inspire WGs and initiatives dedicated to HPC, HTC and Cloud computing. The main target of this collaboration is to contribute to the development of those grid services that can meet A&A application requirements using HPC and parallel systems.
  • Grid Portals and Desktop Grid. A&A VRC is evaluating the state of the art of grid portals and Desktop grids to provide a simplified access to e-Infrastructure for astronomers
  • Workflows. The use of workflows that integrate different kind of resources, HPC, Cloud and Grid, is a core activity to provide a full view to e-Infrastructure to Astronomers.
