Progress of GRID technology in Argentina: Lessons learned

from EELA

•M.T.Dova et al, UNLP – 3rd EELA Conference, Catania, 3-5 December, 2007


The Past

GRID in Argentina before EELA: blah, blah…

We started from scratch with EELA!

2

The greatest impediment to progress is not ignorance,

but the illusion of knowledge.

Outline

Lessons from WP2– UNLP node in the EELA infraestructure– Argentinian CA– Future Plans Lessons from WP3 (HEP)– ATLAS application in EELA– Future Plans Lessons from WP4– Experience from EELA tutorials– Other dissemination activities– Future Plans Prospects of GRID in Argentina



4

Very modest resources, but the first ones in Argentina in a grid infrastructure.

Lessons from WP2 (I) The EELA Infrastructure



5

Resource Centre

• EELA Computing Element

• 6 EELA dual-core Worker Nodes

• EELA 500 GB Storage Element

• EELA User Interface

• Middleware: gLite 3.0.2

• Manager: Andres Barbieri (CESPI)

Housing

• CeSPI Data Centre for UNLP global services

• High availability, high security

• Redundant electrical power feed and cooling, racks and raised floor

• Gigabit LAN

• 20 Mbps link to Internet

• 2 Mbps to Clara through a symmetric link to InnovaRed with BGP routing protocol.


The process for integration of these resources in the EELA infrastructure was

not too simple due to incompatibility between the hardware and the supported

software.

Tier 3

EELA infrastructureSHORT TERM :

• Increase computing power and storage resources.

• Seed for a more ambitious project: to become an ATLAS Tier-3 facility, an important resource for physicists to analyse ATLAS data.

LONG TERM

• Integration at Department levels, then at a provincial (Bs.As.) level, and hopefully at a national level.

UNLP PKIGrid

UNLP PKIGrid Infrastructure

10

The deployment of the PKI has required:

• One portable PC to act as the CA offline• One sure place in order to protect the CA offline• One dedicated server to support the public site of the CA (holding the

Certificates & the CRLs). Supports the functional aspects of the main RA.• One PC for the RA operators• Several Aladdin e-tokens to provide the secure management of operators

certificates• A deployment environment (two separate servers are used for

implementing & testing the info & services provided by the PKI)

Security components:

• One firewall extended to provide a separate DMZ for the PKI service. Default policy is DROP and denials are reported.

• Distributed sensor infrastructure to report events in a central security console to detect security incidents.

• NTP synchronization with a local time source (GPS stratum 0)• Physical Security: RA and Public Site resides in a Server Rack. The access to the rack is controlled. Biometric access.



PKI Implementation tasks

11

• Operative Systems Secure Installation • OpenCA installation• OpenCA GUI adaptation• Checking of the implementation for the fulfillment

of the CP/CPS– Certificates profiles– Configuration of secure operators access (use of

certificates stored in tokens, control of roles)– Token drivers (32K & 64K) -- testing– CA/RA Operator´s training– PKI CP/CPS compliance testing– Digital signature tools testing



12

https://www.pkigrid.unlp.edu.ar

• Bilingual site (English & Spanish)• Site deployment with AJAX• The site contains:

– UNLP PKIGrid CP/CPS– Procedures and documentation– A customized view of OpenCA public interface

Future plans

13

• Continued collaboration with ONTI (Oficina Nacional de Tecnologías de Información de la Subsecretaría de la Gestión Pública de la Nación)e-government

• Computer Security Incident Response Team (CSIRT) at UNLP in the next months.



14

HEP : Argentina in ATLAS


• LHC will collide beams of protons at an energy of 14 TeV.

• Four detectors (ATLAS, CMS, LHCb, ALICE) constructed and operated by international collaborations of thousands of scientists.

• To store and analyse

the huge amount of

data, GRID is crucial.

Argentina (UNLP and UBA) in ATLAS since 2006 .

Lessons from WP3 ATLAS applications

• Currently the ATLAS collaboration is intensively testing its computing model using three types of applications:

- Monte Carlo simulations, which run on all types of Tiers.

- Distribution between Tiers of the Monte Carlo data and of cosmic data.

- Analysis of the data produced either in MC or cosmic runs.• ATLAS applications are specific and use components and services developed either by ATLAS or by the Grid projects to which ATLAS relies on.

These applications run in the ATLAS-Athena framework. All levels of processing of ATLAS data, from HLT to event simulation, reconstruction and analysis, take place within the Athena framework.



Lessons from WP3 ATLAS applications

2006-2007: Training of Argentinean physicists and computing scientists at ATLAS Offline-computing and High-Level Trigger groups.October 2007: ATLAS EELA-MOU approved and signed.November 2007: ATLAS applications installed @ the UNLP RC (with great help from Alessandro De Salvo, Pedro and Diego!)November 2007: Athena test jobs successfully run.

November 21, 2007: First reconstruction job

submitted and running!!

The Future


Monte Carlo jobs submission on the EELA e-Grid

infrastructure from the ATLAS production system. Distributed Analysis jobs submission on the EELA

e-Grid infrastructure from the ARDA-Ganga system

and Management of the data using the ATLAS

Distributed Data Management system. (See more in

D. Barberis talk.) Continue plans for deployment, development and

training milestones through EELA2 Gridification of AIRES MC for simulations of ultra-high

cosmic rays.


First Step: to learn, practice and experiment using GILDA, the INFN real grid computing infrastructure completely devoted to dissemination activities.

Second Step: Training of tutors (tutorials for users and administrators)

Third Step: Organization of tutorials in Argentina

and participation of tutors in events in the region (LA)

Prospects of GRID in Argentina


• The Joint Research Unit already created with support from SECyT (Secretariat of Science, Technology and Productive Innovation)


• Goals:– Support the development of support infrastructures for

distributed computing aimed at sharing resources for the resolution of complex problems with demanding computing requirements

– Facilitate the use of GRID Technology: e-Science, e-Education and e-Government

– Ensure the development of competence and capacity for the evolution of GRID computing in Argentina and the national initiative (together with InnovaRed).

– Dissemination of GRID technology to the industry, government and general public

– Integrate Argentina in major International Grid computing infrastructures

26

Argentinean e-Science Collaboration Network



27

Argentina in others LA grid initiatives



EELA has provided the framework for e-Science in Argentina– Argentinean professionals trained in GRID technology– Participation and organization of Tutorials for administrators and

users (National and International)– Creation of the Certification Authority Centre for e-Science in

Argentina (http://www.pkiunlp.edu.ar)– Small node in EELA infrastructure, will evolve in a Tier 3.– ATLAS applications in EELA

Summary and Conclusions

e-Science in Argentina runs in the right direction and with the right slope.

EELA has been crucial to get us here! Good prospects for Grid initiatives in Argentina
