Ph.Gavillet on behalf of the GISELA Project
EGI Technical Forum, 19th-23rd September 2011Lyon (France)
EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 3www.gisela-grid.eu 3
GISELA as Resource Provider
– General is much experienced in Grid computing has a powerful Infrastructure complies with EGI policies & recommendations
– Specificities Both Service (gLite) and Opportunistic Computing (OurGrid) supported
EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 4www.gisela-grid.eu 4
Long record in e-Science support
• Fruit of 5-6 year experience of successful e-Science EU-LA Collaboration, through EU funded projects (EELA, EELA-2, GISELA)
• Present in almost all LA countries
• Most encompassing e-Infrastructure for scientific collaborations between Latin America and Europe
• Sound long-term sustainability approach rooted on CLARA, NRENs, LA NGIs

EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 7www.gisela-grid.eu
EGI compliant Infrastructure
• EGI – UFRJ (on behalf of GISELA) Resource Provider MoU
• EGI compliance is based on the adoption of common services and practices
– The Operational Level Agreement (OLA) (http://documents.gisela-grid.eu/record/87?ln=en)
– Monitoring System (Nagios)
– Ticket System (xGUS)
– Accounting System (APEL)
– Middleware (gLite)
– Resource database (GOCDB)
– Operations Dashboard
EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 8www.gisela-grid.eu 8
Specificity: gLite <-> OurGrid interoperability
• Latin American context:– Large Universities (UFRJ, USP,…) in International collaborations thus
complying with the corresponding computing model and middlewares (gLite, OSG,..)
– Several small Universities naturally adopting the Desktop-based opportunistic Grid approach and using the OurGrid middleware

GISELA: an opportunity for VRCs
– Platform for all kinds of Applications– Offers a series of well-supported Services (e.g. DIRAC)– Training & Support– Collaborates with EGI and Regional Initiatives
EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 10www.gisela-grid.eu
Platform for all kind of Applications / VRCs
10
• VRCs– A few large VRCs from Life Sciences (e.g. WeNMR, Biomed), Earth Sciences (WRF4G,
Seismic simulations) and HEP (Auger, LHC expts) – Legacy: EELA-2 User Communities, typically 1-2 Institution group(s), largely located in
Latin America– 34 Applications are in a production stage
• MoU signed with EGI-InSPIRE enables…
– VRC members in Europe exploit GISELA resources– VRC members in LA exploit EGI resources (most usual)– Publishing GISELA applications in the EGI Applications data base http://appdb.egi.eu/

Usage statistics
11
• Accumulated CPU-hours, grouped by VOs:
• prod.vo.eu-eela.eu: catch all VO (Earth Sciences, EELA-2 legacy,..)

Portfolio of Services
• Supported services (extract) :– Application-related Services
Job Catalogue, File and Data Management• Digital archives, Secure storage, WatchDog, lcg-rec toolkit
– Data processing and user analysis services DIRAC: workload and data management system
• Possibility of development of new services– Industry portal– Dynamic creation of Customised Virtual Clusters (CVC -
Uniandes)– Development of a VRC-driven Web site
EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 13www.gisela-grid.eu 13
DIRAC as a complete VRC solution
• DIRAC is a complete VRC Grid solution
• Already used by several large VRCs:– HEP (LHCb, Belle, ILC, Magic)
– BIOMED(VIP)
• Development coordinated by CPPM (Marseille), a GISELA Partner
• Fully supported within WP6

Collaboration with EGI & Regional
projects • EGI
– Resource Providers MoU, signed with EGI-eu– Project MoU (Dissemination, Training, Support tools & Services),
signed with EGI-InSPIRE
• EGI-related projects / Regional Initiatives
– DEGISCO (UFCG-Brazil also partner) Volunteer computing support (gLite <-> OurGrid bridge)
– CHAIN (CLARA, INFN, CIEMAT also partners) (MoU foreseen) Focus on VRC support (e.g. training)
– EPIKH (Brazil: CEFET/RJ, UFRJ, Chile: UTFSM, Mexico: UNAM) Joint sponsoring /organisation of Tutorials & Workshops (MoU signed)
– EU-IndiaGrid2 (MoU signed)

GISELA interests
– Welcome international VRCs– Interest in VRCs collaborating with LA– Efficient communication scheme between VRCs and GISELA – Efficient collaboration with EGI on VRC support
EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 16www.gisela-grid.eu 16
GISELA interests (1/2)
• Welcome international VRCs– DoW: “GISELA is open to collaboration with institutions / projects, public or
private, whose activities are compatible with its Objectives”
– On top of mentioned VRCs, production from Earth Sciences (Academia Sinica), Astrophysics team (UFRJ-BR), Solid state physics team (UFRJ-BR)
• Interest in VRCs collaborating with Latin America– GISELA is naturally (but not exclusively) looking for existing or foreseen
collaborations with Latin America
• GISELA <-> VRC: Simple, albeit efficient communication scheme– Vilnius – EGI UF
At an early stage have a concise Technical document defining the characteristics of VO, Applications, WE, SE, batch queues, support aspects,…
One point-to-point interface covering all matters (VO-related, training,...) Definition of a simple follow-up scheme, monitoring of activities based on
standard tools (e.g. NAGIOS screen…)– Lyon – EGI TF
Status: to be discussed at this Workshop
EGI Technical Forum (19-23 Sep. 2011 - Lyon / France) 17www.gisela-grid.eu 17
GISELA interests (2/2)
• GISELA – EGI: Efficient cooperation via the User Community Support Team (UCST) and the User Communities Board (UCB):
– EGI-InSPIRE – GISELA Project MoU as instrument to coordinate VRC support
• Common (RPs – VRCs – EGI) dissemination / outreach activities – Common participation in UCST, UCB
– GISELA – e-ScienceTalk MoU (signed) as instrument of coordinated dissemination
Use channels as the GridCafé, GridCast, iSGTW and GridGuide
– Cross participation in Forum, Conferences,…
