  1. Computing in HEP(plan) • Introduction • The scale of computing in LHC • Regional Computing • Russian Regional Computing Facility • Institute Level Computing • Computing cluster at PNPI • Computing cluster at Stony Brook • Conclusion Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  2. Introduction • PNPI - St. Petersburg Nuclear Physics Institute (http://pnpi.spb.ru) • High Energy Physics Division • Neutron Physics Department • Theory Physics Division • Molecular and Biology Physics Division Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  3. CSD responsibilities • HEPD Centralized Computing (http://www.pnpi.spb.ru/comp_home.html) • Computing Cluster • Computing Server • HEPD Local Area Network • HEPD and PNPI Connectivity (excluding terrestrial channel) • HEPD and PNPI InfoStructure Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  4. High Energy Physics Division Computer LAN • About 200 hosts • Most of them are 10Mbit/sec • Central part of LAN consists of 100Mbit/sec segments (Full Duplex) • Based on 3Com Switches 3300 • LAN is distributed over 5 buildings • Effective distance is about 800 m • Fiber Optic Cable is used in between buildings Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  8. Related Proposals CERN GRID site http://grid.web.cern.ch/grid/ • Particle Physics Data Grid (http://www.cacr.caltech.edu/ppdg/) • High Energy Physics Grid Initiative (http://nicewww.cern.ch/~les/grid/welcome.html) • MONARC Project (http://www.cern.ch/MONARC/) Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  9. What is an inspiration? • Last year (1999) that book became famous. • Immediately after a range of proposals were submitted to various agencies and funds. • Main idea is to create World Wide Computing Infrastructure. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  10. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  11. RRCF in St.Petersburg • Possible partners • Petersburg Nuclear Physics Institute; • S.Petersburg University; • S.Petersburg Technical University; • Institute for High Performance Computing & Data Bases; • RUNNET ? Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  12. Russian Reginal Computing Facility • Regional Computing Centre for LHC • CSD takes participation in Russian activity in creating the Russian Regional Computing Centre for LHC (see http://www.pnpi.spb.ru/RRCF/RRCF) Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  13. RRCF in St.Petersburg Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  14. RRCF in St.PetersburgComputing Power • Total Computing Capacity about 90K SPECint95 • http://nicewww.cern/ch/~les/monarc/base_config.html • Pentium III/700 has about 35 SPECint95 • About 2570 processors • or about 640 machines for 4 processor • or 640/4 (institutes) = about 160 machines. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  15. Computing Cluster PC/II/400/128 EIDE 6GB PC/III/450/256 EIDE 6GB PC/II/266/256 EIDE 5GB Switch 100Mb RedHat 6.1 CODINE CERNlib Root http://www.pnpi.spb.ru/pcfarm Dual PII/450/512 Ultra2WideSCSI 18GB Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  16. BCFpc hardware (picture) Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  17. Another Examplefor Computing Cluster • University at Stony Brook, Departnet of Chemistry, Laboratory of Nulear Chemistry • DEC Alpha 4100 (500 MHz). • 32 machines (dual PIII/500, 256 MB); • Tape Robot for 3 TB; • RAID array 1.5 TB. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  18. Problems • Security • against attacks from Internet and Intranet; • against unplanned data losses; • To keep up to date the software base on whole cluster. • To save network bandwidth by keeping locally the special cache for experimental data. • Appropriate Batch System. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  19. Possible Plan for Small Physics Laboratory • To install the hardware: (3-5) PCs (about 0.8-1.3 GHz, 0.5GB of main memory, DLT stacker on the base DLT-8000, Switch with 1 Gbit uplink, etc., etc.). • To install the software: Linux, CERNlib, Objectivity/DB, GLOBUS, etc., etc. • To prepare and test logical connectivity to CERN and to Regional Computing Facility for LHC. Reporter: Andrei.Chevel@pnpi.spb.ru -- From: PNPI

  20. Conclusion • Relatively new situation for many small and midrange laboratories (like PNPI): • Main direction in HEP computing at PNPI is to create good front-end for High Performance Computing Facilities plus MSS outside Institute. • We have to collect all the available financial, technical, administrative resources and plan to work in close collaboration.
