Alex Read, Dept. of Physics Grid Activity in Oslo CERN-satsingen/miljøet møter MN-fakultetet Oslo, 8 juni 2009 Alex Read

Alex Read, Dept. of Physics Grid Activity in Oslo World-wide LHC Computing Grid (Norway~1.8%) Advanced Resource Connector (ARC) middleware- related projects Norwegian Tier-1(+2) sites Tier-3 status Ganga (multi-grid job submission tool for LHC++) ARC performance in ATLAS production Participation in and/or influence on Norwegian, Nordic, European grid initiatives

Alex Read, Dept. of Physics Norwegian resources for WLCG –Provided outside the HEP projects (ALICE & ATLAS) Tier-1 & 2: Binding through MoU  yearly basis Tier-3 for analysis “self-funded” NorGrid/NOTUR Small contributions from NFR projects –2 Grid-related post-docs for Alice and Atlas (50% HEP projects, 50% Uninett-Sigma/Norwegian eScience - eVita) –1 in Oslo EPF F. Ould-Saada

Alex Read, Dept. of Physics Oslo participation (and quite some leadership) in the NorduGrid Collaboration and the 3 ARC middleware- related Grid projects NorduGrid Collaboration ( –Develop, support, and coordinate inputs to the Advanced Resource Connector (ARC) middleware, Oslo in from the beginning in 2001, current leader The KnowARC project ( –Create a novel, powerful Next Generation Grid middleware based on ARC and bridge the gaps between business and academia in Grid development (leadership and large contr. From Oslo) NDGF ( –NDGF is a production grid facility that leverages existing, national computational resources and grid infrastructures  Nordic Tier-1 and external Tier-2’s NGIn ( –Train new Grid experts, securing further technology development  5 PhD grants (2 in Oslo!), Grid school Projects Collaboration ARC ~ 2M Euros / year Farid Ould-Saada (rest of ATLAS is jealous)

Alex Read, Dept. of Physics Grid activities at UiO / USIT Tier-1, Tier-2 (NDGF) compute resources –4000 core cluster (titan), Condor pool –Atlas (significant fraction of Nordic T1) –Alice production (to resume spring ‘09) –362 dedicated cores ->552 dedicated cores (April 2009) –free resource (idle cores) –Regularly see > 1000 grid jobs –NorGrid production site Tier-1 storage pools (dCache) –120 TB 2008, 260 TB (April ‘09) Hans Eide

Alex Read, Dept. of Physics Grid activities at UiO / USIT (cont.) Collaboration between HEP group and USIT –Middleware development (ARC) –Graduate students (2) –Jon Kristian Nielsen (storage) –Dmytro Karpenko (workflow) Building up Tier-3 for physics analysis CPU allocation from NOTUR (87 kh, ) 9 TB dedicated storage 32 Interactive Hans Eide

Alex Read, Dept. of Physics Distributed analysis in ATLAS Ganga is the primary tool in ATLAS to submit user analysis jobs to the WLCG (which has 3 diverse middlewares: VDT, gLite, ARC) Oslo EPF supports the ARC backend Ganga in action Bjørn Samset

Alex Read, Dept. of Physics Performance of ARC-enabled NDGF Jan-Sep 2008

Alex Read, Dept. of Physics Get on the grid...snip... The default grid middleware that is used by the NorGrid initiative is the Advanced Resource Connector (ARC). You need to install the ARC middleware client on your local desktop. There is a wealth of documentation on ARC middleware. In particular, the ARC User Guide is recommended literature. clientdocumentationARC User Guide...snip...

Alex Read, Dept. of Physics 24/10/2015F. Ould-Saada10 Principal goal is to establish a Nordic eScience committee and management structure Activities include programme plans for resourcing computational grand challenge research (like LHC...) An expert group on Grid infrastructure is established: NDGF, Nordic participation in WLCG (including LHC upgrade plans) are among central topics in the mandate of the group. eNoria – The Nordic eScience Initiative

Alex Read, Dept. of Physics Establishing a sustainable grid (EGI) Thanks to NorduGrid, NDGF (and others), production grids are reality today F. Ould-Saada

Alex Read, Dept. of Physics 24/10/2015 OSLO Workshop: March Next workshop: CERN April Common EU application towards end of 2009? Common middleware for LHC and other applications? Towards a first implementation of UMD Proposal 2/3/2009 Farid Ould-Saada et al F. Ould-Saada

Alex Read, Dept. of Physics Summary Oslo participates in and leads a number of Nordic and European Grid projects The Norwegian contribution to WLCG is in good shape The utilization of the ARC-enabled resources is excellent –NDGF (distributed Tier-1) is a great success The Norwegian grid infrastructure for computational science is well-established and growing Grid activity in Oslo is strongly influencing the Norwegian, Nordic and European scenes

Alex Read, Dept. of Physics F. Ould-Saada Seen as One site from CERN! Distributed!

Alex Read, Dept. of Physics ATLAS Production System 15 Task request interface prodDB: jobdefs, job states, metadata Input: DQ2 datasets Task states Output: DQ2 datasets 3 grids/10 Clouds Monitor sites, tasks, jobs Panda

Alex Read, Dept. of Physics Tier-3 coming along Norwegian resources useful for LHC analysis (stallo, titan) are ARC-enabled
