Slide4:  Presampler of the ATLAS E.M. Calorimeter Grenoble (LPSC) – Stokholm and Morocco 1 wheel of 32 sectors Slide5:  Maroc Wide Area Network MARWAN 2 Network at 34 Mbps for Research and high education 45 Mbps 34 Mbps 2 Mbps Rabat Casablanca Slide6:  Institutions connected to MARWAN 2 27 Links to MARWAN 2 (19 @ 2 Mbps + 8 @ 34 Mbps ) March 2005 Some Characteristics of Digital Divide in Morocco : - MARWAN2 @ 34 Mbps (many cases @ 2 Mbps) - Majority of links University – Institutes are @ 2 Mbps (cost is about 2000 Euros per month) - Monopoly of one operator Maroc-Telecom - Problem of Manpower and organization - poor participation in large scientific collaborations (LHC, …), Moroccan HEP network in ATLAS is unique example in Africa Slide7:  Country providing resources Country anticipating joining In LCG-2: 113 sites, 30 countries > 10,000cpu > ~5 PB storage Includes non-EGEE sites: 9 coutries, 18 sites Computing Resources: Feb 2005 South Africa Morocco Computing and equipement:  Computing and equipement Analysis of the combined test beam data : July-October 2004 7.7 Million events fully simulated (Geant 4) 22 Tbyte of data Slow progress using interactive data analysis at CERN Necessity of using Gridftp for data transfer Joining LCG is a matter of urgency for us Existing cluster at the Casablanca site 6 CPUs (2.4 GHz) with 512 MB of RAM 10 CPUs ( 2.4 GHz) with 256 MB of RAM Storage capacity about 700 GB Operating system is Linux RedHat Entreprise WS3 and Fedora and Linux scientific Joining LHC computing Grid (LCG):  Joining LHC computing Grid (LCG) Joining LCG : Memorandum Of Understanding (MOU) for Collaboration in the Deployment and exploitation of the LHC computing Grid , autumn 2005 Building a Morocco tier-2 federation including the institutions of the HEP network. Casablanca, Rabat, Oujda, Marrakech, Settat, CNESTEN and CNRST CNRST : National Center for Scientific and Technologic Research In 2006 extension of the existing cluster of Casablanca Linux farms of PC clusters 15 CPUs (2. GHz) 1 GB of RAM Storage capacity of 3 Tbytes An other Cluster at CNRST (Rabat) dedicated to EUMEDconnect and LCG will be equiped in the beginning of 2006, with roughly the same equipements as Casablanca In november 2005 : Training course on network security and Grid. B. Boutrain from LPSC/Grenoble - IN2P3 Morocco Tier2 federation supported by CC-IN2P3 Tier1 :  Morocco Tier2 federation supported by CC-IN2P3 Tier1 Extension of the existing cooperation agreement Morocco-IN2P3 to include Grid activities. Meeting was held at CCIN2P3 (Lyon) on Friday 20 May 2005 Training at CCIN2P3 to unify technical and operational management, summer 2005 Grid Technology ( 1 person ) Software and applications ( 1 person) To use IN2P3 Grid certificate To fulfill LCG and ATLAS technical and practical requirements (ATLAS-GTTF) The agreement will be signed in September 2005 Casablanca Conference : Sharing knowledge across mediterranean area (5-6-7 September 2005) Session on Digital Divide, Chair : G.
