1 EasyGrid: the job submission system that works! James Cunha Werner GridPP18 Meeting – University of Glasgow

2 User software User computer Datasets Grid enabled software User software + Gridification algorithms Workload management Data Management Performance analysis Grid resources Gridification Process: from conventional to grid computing. Data Gridification Functional Gridification EasyGrid Job Submission system Submit jobs Manage datasets Recover results Recover reports > BetaMiniApp Tau11-Run3.tcl > Easygrid BetaMiniApp Tau11-Run3 See for more information Many files in sequence Many files in parallel -> Fast File name Dataset name

3 Retrospective Available since GridPP11 - September/2004 : Several benchmarks with BaBar experiment data : Data Gridification: –Particle identification: –Neutral pion decays: –Search for anti deuteron: Functional gridification: –Evolutionary neutral pion discriminate function: Documentation (main web page): 109 html files and 327 complementary files 60 CPUs production and 10 CPUs development farms running independently without any problem between November/2005 and September /2006.

4 EasyGrid in production: results with real data

5 Results data gridification Source Dr Mitchell Naisbit

6 Date: Thu, 22 Dec :51: From: Roger Barlow To: Subject: [BABAR-USERS] Manchester babar Dear Manchester BaBarians, 2 bits of good news. 1) easyroot works. I have carefully idiot-proofed it, and if I can make it work then anyone can. Today it gives access to a small farm, meaning you can run several jobs in parallel and speed up your tauuser analysis by an order of magnitude. Soon we will enable the rest of the existing BaBar farm. And before long we have the 1000 node Dell farm. For brief instructions see For full instructions see 2) we have a new big disk, thanks to Sabah. 1.6 TB. We need to decide what to put on it (and what to call it.) Father Christmas has been busy... Roger

7 Tau to ηπν Source Dr Marta Tavera

8 Functional Gridification: NPDF Final results for several energy cuts -α: Sensitivity or efficiency. -β: specificity or purity. -γ: accuracy.

9 Hadronic tau decays results:

10 Dissemination 20 international events: 5 refereed papers Int. Conferences. GridPP stand at IoP2006 and IoP2007. Contributions at GridPP web pages. Users support at France, Switzerland, New Zealand, etc: LCG and BaBar software, grid and cluster computer, etc.

11 Research beyond HEP Effect of complexity in NP hard optimization modeled with genetic algorithms always feasible chromosome.

12 Visual C++ framework for EasyGrid results visualization
