Abstract
DIRAC (Distributed Infrastructure with Remote Agent Control) is a general framework for the management of tasks over distributed heterogeneous computing environments. It has been originally developed to support the production activities of the LHCb (Large Hadron Collider Beauty) experiment and today is extensively used by several particle physics and biology communities. Current (Fermi Large Area Telescope – LAT) and planned (Cherenkov Telescope Array – CTA) new generation astrophysical/cosmological experiments, with very large processing and storage needs, are currently investigating the usability of DIRAC in this context. Each of these use cases has some peculiarities: Fermi-LAT will interface DIRAC to its own workflow system to allow the access to the grid resources, while CTA is using DIRAC as workflow management system for Monte Carlo production and analysis on the grid. We describe the prototype effort that we lead toward deploying a DIRAC solution for some aspects of Fermi-LAT and CTA needs.
Highlights
The Large Area Telescope (LAT) is the primary instrument on the Fermi Gamma-ray Space Telescope mission, launched on June 11, 2008
In order to fulfill present and future requirements for MC massive production and data analysis of Fermi -LAT and Cherenkov Telescope Array (CTA), we have proposed the use of the EGI grid infrastructure and of the DIRAC (Distributed Infrastructure with Remote Agent Control) [8] framework for both current and future experiments
In order to interface the production workflows with the DIRAC File Catalog (DFC), we have first identified the meta-data that are relevant for searches (MC software version, particle flavour, CTA site altitude, telescope array configuration, etc.), as well as non-searchable ones
