Status of analysis & MC farms Concezio Bozzi INFN Ferrara 30/08/2002
Three farms in Italy today: “MC”: for official Simulation Production (formerly at Caspur, now at INFN Rome) “Analysis”: a Tier B with Kanga data located at Caspur (Rome) “Repro”: located in Padova, will reprocess all Babar Run1+Run2 data starting this summer The name of the game Concezio Bozzi (Ferrara)
MonteCarlo Farm Today Upgrade Analysis Farm Today - Upgrade INFN Farms in Rome MonteCarlo Farm has been moved June 15th from Caspur to INFN (Rome) The Analysis Farm is still at Caspur Concezio Bozzi (Ferrara)
MonteCarlo Farm today • 1 server Linux, dual cpu, PIII 800 MHz, 512 MB • (NFS and lock servers, batch queues, MocaEspresso) • 14 Linux clients, dual cpu, PIII 800 MHz, 768 MB • 2 Array RAID EIDE : 2x0,5 = 1 TB • Event rate: 3.5 M events/month 30 M events in 1 year Concezio Bozzi (Ferrara)
Farm MonteCarlo: comparisons … Concezio Bozzi (Ferrara)
Farm MonteCarlo: comparisons … 19.4 M events from August 15th 2001 to June 15th 2002 Concezio Bozzi (Ferrara)
Farm MonteCarlo: comparisons … we are here !
MonteCarlo Farm: CPU SCSI problems stop/start production re-validation Concezio Bozzi (Ferrara)
MonteCarlo Farm: disk & net Concezio Bozzi (Ferrara)
MonteCarlo Farm: Upgrades • 2002: increase production to 6-8 Mevents/month • clone Linux farm • 17 2-CPUs, 1.26GHz, 1 GB RAM: installing now • Server and disk (1TB) ordered • use Analysis farm resources when available • Problems with a Sun disk (1TB), recovering… • 2003: increase production to 20 M events/month • more CPUs (150*30SpecInt95 ~ 35 1.6GHz 2xCPUs) • use repro farm whenever possible Concezio Bozzi (Ferrara)
Analysis Farm: Today • 5 Sun E450, 4x400 MHz, 2GB (NFS data server) • 15 Linux clients, dual cpu, PIII 1 GHz, 1 GB: • 1 Sun Ultra 10: lock server - 1 Sun Ultra 10: monitoring (to be dismissed soon) • Disk space: 9 TB for Kanga • Data: AllEvents + 8 streams. The complete (99-02) dataset is available • MC: ~650M events available • Private & Toy MC • SP MC production as “infn2” (lower priority wrt analysis) Concezio Bozzi (Ferrara)
Analysis Farm: users SUN Linux Concezio Bozzi (Ferrara)
Analysis Farm: jobs CPU efficiency Running jobs Linux Pending jobs Concezio Bozzi (Ferrara)
Analysis farm: Upgrade 2002: • 17 Linux clients, dual cpu (in hand) • 3TB disk space (ordered): 15TB total This will be enough until March 2003 2003: • cpu power x3: 210 30SpecInts95 (50 1.6GHz 2xCPUs) • Disk: from Padova (?) • maintain Kanga until end of reprocessing, (spring 03) • Next: Computing Model Working Group OBJY vs. non-OBJY Event Store, MINI vs. MICRO, etc… Concezio Bozzi (Ferrara)
Babar-Grid • Some activity going on in Italy • Define and implement a Grid-scheme for MC production • Installing/testing on the INFN-Grid Ferrara testbed Concezio Bozzi (Ferrara)
Farmers …. • Ferrara: D. Andreotti, V. Azzolini, C. Bozzi, E. Luppi + CS students • Padova: A. Ceseracciu, A. Crescente, A. Dorigo, F. Galeazzi, M. Marzolla, M. Morandin, R. Stroili, G. Tiozzo, G. Vedovato • Rome: C. Bulfon, F. Safai Tehrani • Trieste: G. Della Ricca Concezio Bozzi (Ferrara)
