Memories of the past

A&A community using Grid technology since 2003:

•Pioneering the access to databases (GDSE)•Pioneering instruments control via Grid (Astro-IE)•Data Analysis and simulations

•A&A participates to the EGEE, EGEE-II, EGEE-III

•Large projects•Small projects

•Interoperability with other eInfrastructures (VObs)A&A workshop Paris 6 November 2011 •2


Successful stories

• Instrument Element: instrument control via Grid infrastructure.

• G-DSE: accessing databases via Grid

• A&A science gateway portal (2003!!!) for data reduction and analysis

Projects and Applications



The Early Days

• Planck Satellite Mission: • Pre-launch simulations activities

• Involves both EGEE and DEISA• Monte Carlo simulations (post-launch)

• MAGIC Telescope:• CORSIKA Monte Carlo code

• Hadronic showers • Instrument response = simulated data sample



MAGIC project

• Scientific Goals: Dark Matter, Cosmic Rays, Quantum Gravity, Cosmology …

• The MAGIC collaboration:• 21 institutes (mostly in Europe)• ~ 200 members

• Telescope site in Canary Islands• Observatorio Roque de los Muchachos• MAGIC-I: operating since 2004• MAGIC-II: in commissioning (2009)


•8

• MAGIC is a Cherenkov telescope system for g-ray astronomy in the very high energy range (VHE, E > 25 GeV)


Planck Satellite

• PLANCK ESA Space Mission (2009). Measure the Cosmic Microwave Background Radiation.

• Scientific Goals: Cosmology, CMB anisotropies and polarization, galaxy cluster (SZ effect), gravitational lensing, etc.

• The Planck collaboration:• Europe and USA • More than 500 scientists

• Launched 14 May 2009•9A&A workshop Paris 6 November 2011


EGEE Astro Cluster

• Support Cluster in EGEE-III

• User support: training, application porting

• User support: middleware customization, VObs gateway, training dissemination.

• Manage the transition to EGI:• From A&A Cluster to A&A VRC• A&A Heavy User Community


•10


From EGEE to EGI

• Year one: Specialized Support Centers• ROSCO• SAFE

• Year two: FASE and the generic A&A VRC• Astro-DSE

• Both projects were rejected


•11


Interoperability



The Virtual Observatory

• “A virtual observatory is a collection of interoperating data archives and software tools which utilize the internet to form a scientific research environment in which astronomical research programs can be conducted.”

• Service Oriented Arch

• EuroVO (www.euro-vo.org)

• EuroVO-DCA • WP4 interaction with GRID



VObs and EGEE interoperability


•14

• Scientific Gateway: bridge two eInfrastructures.– VOSpace vs LFC– UWS vs WMS– Auth and Auth

• Desktop Grid: VODesktop


ESAC example

•15

•Save Results on•VOSpace

XMM-Newton RISA – Remote Interface for Science Analysis

•Vizualize Results with•VO tools (VOSpec, Aladin)

•VO Access data

•VO Display•Request

•VO Search data

•XMM-Newton Archive

•Define SAS Tasks

•Search data with RISA Web client

•Run SAS tasks on ESAC GRID

•VO Download data

•Send SAS Tasks•To the GRID

•GRIDWAY

A&A workshop Paris 6 November 2011


This is not the whole story

• Planck activities in Italy and Spain: LevelS and non Gaussianity studies

• PDR code (Le Petit et al) : study of the interstellar medium

• Dynamics of the solar system (Laskar & Gastineau)

• Very High Energy Astrophysics (Lenain)

• CTA Computing Grid (Lamanna)



This is not the whole story

• Astro-WISE• Dynamical models for Galaxies• ZEN project• AUGER• SYNTSPEC @ BalticGrid (Poster 3)• Kuiper-belt and Oort-cloud formation

(Institute of Informatics Slovak Academy of Sciences)

• Image data reduction • Etc….



The A&A Community in EGI

• Astronomy and Astrophysics is a Heavy User Community in EGI.eu

• One “catch all” A&A VRC• “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.”

• Support and coordinate A&A communities

Are we doing something?


•21

• A number of activities is in progress within the A&A HUC (not yet VRC)• Participation in EGI-InSPIRE

• INAF (Italy): TSA3.5• II-SAS (Slovakia): SA1, SA3• Others …

• Tools have been set up to foster collaboration• A TWiki web page • A catch-all mailing list• Others will be set up at a later stage


Twiki Page

• Twiki as collaboration tool

• News and events

• Locate documents

• Software and VMs images repository.

• Pointer to A&A VRCs Portals• We aggregate information


•22


A&A community services

• Poster 151 ADASS

• Specialized services (WMS, DMS etc.)

• Based on virtualization

• Easy support middleware

• Easy migrate

• Easy deploy


•23


Community A&A software

• IRAF (PyRAF):• Images operations;

• Midas-09Sep• Data reduction (bias+flat+mosaic) on FORS1 images of NTT DF;

• SEXTRACTOR-2.3• 400x400 pix GOODS DF images;

• Swarp 2.10;• Eclipse-4.2.0

• dfits on 400x400 pix GOODS DF images;•EGEE User Forum - Upsala 14 April

2010•24


Community A&A software

• Cloudy-94• IDL (GDL) Astro pack• SM plotting tool• Scisoft• DS9• Cfitsio (with gridftp support)


•25


Some major issues

• But….astronomers are bad guys• Community fragmented with heterogeneous

needs and requirements• Almost all A&A VOs active in EGI relate to

Astro-Particle Physics

• Key A&A large projects still missing (e.g. ESFRI projects: E-ELT, SKA)

• A&A HUC not yet officially endorsed by EGI as a VRC: a MoU of at least a LoI has to be subscribed


•26


What we expect from the future



Data Avalache

• Images and data from thousand observation and simulations

• New instruments• 40 M telescope (1TBxImage)• Cherenkov Telescopes Array (CTA)• New super computers

• New satellite missions• e.g. EUCLID



Grid And HPC

• Numerical Simulations• New Simulations need to

be analyzed• Small scale simulations

on the Grid

• PRACE new paradigm

• TriGrid experience• HPC WG (Dr. Becciani)• www.trigrid.it



High Energy Astrophysics

• ASPERA: AStroParticle ERAnet• a roadmap for Astroparticle Physics in

Europe• stimulate coordination and cooperation within

the European astroparticle community• Auger, ARGO, MAGIC and HESS• Also computing and data management

• Future for astroparticle is CTA observatory
