e-Science activities

Currently, science is performed in more and more collaborative environments, where international groups share not only databases but instruments as big telescopes, microscopes, etc, as well as interchange knowledge tools as e.g. access grid rooms. The e-Science (enhanced - Science) arises as the solution to the challenge that implies this new scenario. The e-Science is supported by e-Infrastructures, a new type of infrastructures that combines well known elements as internet network and computing resources in order to provide suitable services that allow the actual collaboration between researchers from different institutes and fields of research, with new ones, as scientific workflows, collaborative platforms or the Semantic Web.

INITIATIVES

  • E-CA project

    The first regional initiative of e-Science in Spain, entitled "Building an e-Science infrastructure for Andalucía", has been promoted from the IAA based on an Excellence Project funded by the regional government. This project involves 15 groups from different parts of Andalucía covering a large variety of scientific fields, sharing their interest in the development of a regional infrastructure for e-Science and promoting e-Science activities. The project actively collaborates with national initiatives such as the network of Spanish e-Science.

    The first steps for the implementation of a GRID infrastructure in Andalucía have been performed within this project: the creation of a virtual organization and the implementation of a resource centre. Another goal of the project is to promote the use of e-Science tools among groups sharing similar problems. For that purpose a repository has been created containing detailed information on the expertise, software and hardware resources of the regional research groups and companies interested on e-Science, named the Yellow Pages of Andalusian e- Science (http://e-ca.iaa.es/paginasamarillas). The compiled information is accessible by a public Web interface, and is intended to promote multidisciplinary synergies as well as collaboration with private companies.

  • E-Science Spanish Network

    The IAA belongs to e-Science Spanish Network, and participates as member of the Applications Area committee.

COMPUTING INFRASTRUCTURE

  • GRID-CSIC

    The Spanish National Research Council-CSIC has deployed a distributed computing infrastructure to facilitate CSIC researchers the accomplishment of scientific projects requiring computing resources beyond the capabilities of a single user or research group. GRID-CSIC has been therefore given the structure of a Horizontal Unit inside the Council. The coordination is performed from the Institute of Physics of Cantabria (IFCA), in Santander.
    The IAA maintains one of the nodes of GRID-CSIC composed by 42 compute nodes with 16 cores and 128 GB RAM each. The storage system is about 240 TB served by GPFS .
    The IAA grid node belongs to the Spanish National GRID initiative as well as to the European Grid Infrastructure (EGI)

  • Supercomputing and distributed computing. Simulations for the study of the evolution of galaxies in groups of galaxies were carried out at
    1. the MareNostrum Supercomputer of the Barcelona Supercomputing Center in the frame of the IDILICO (Investigation of the DIffuse LIght COmponent in compact groups of galaxies) collaboration between researchers of the IAA, Universities of Barcelona and Rovira i Virgili and the Observatoire de Marseille
    2. at the CESCA (Centre de Supercomputació de Catalunya) and currently at c) the Hypercat cluster of the IAA where also the analysis is performed.

DATA-MINING AND VIRTUAL OBSERVATORY (VO)

  • We have prepared a large amount of data tools for the observational data reduction and analysis of the first Spanish Guarantee Time project for the 3.5m telescope at Calar Alto, the ALHAMBRA project. Our first aim was the preparation of data reduction pipelines for image processing in the optical and the infrared. This pipelines are designed to be non interactive and they handle, archiving, debiasing, flat fielding, astrometry, image combination, object detection and photometry calibration (already prepared), photometric redshifts and object morphology (started). The ALHAMBRA archive will be integrated in the VO.
  • Due to the implied intensive analysis of 3D data at all wavelengths a collaboration has been already started with the Kapteyn Institute for upgrading the GIPSY software, producing a friendly VO-integrated package for high-level analysis of 3D data cubes, fully compatible with ALMA data.

 

COLLABORATIVE TOOLS

  • Wf4Ever project

    Since 2010 the IAA is involved in a EU FP7 funded project - Wf4Ever: Advanced Workflow Preservation Technologies for Enhanced Science (7PM- 270192) - in order to package the full scientific methodology in a digital container that keeps the lifecycle of an experiment, linking data and services for their analysis, going for publication beyond the pdf. This implies the development of standards and models for the preservation of the different aspects involved in the research lifecycle. The scientific workflows, as a the way to achieve an efficient exploitation of the huge volume of data currently available, will play a key role in this project, in order to turn them into the way to push Astronomy to share and publish not only results and data, but also processes and methodologies.
