1 Site Report Stephan Wiesand DESY -DV

2 Where we're headed HERA (H1, HERMES, ZEUS) HASYLAB -> PETRA III PITZ VUV-FEL: first experiments, X-FEL: in planning stage ILC: R & D LQCD: parallel computing Theory participation in Amanda -> IceCube future: participation in either ATLAS or CMS offer to run a Tier 2 centre for both

3 GRID Deployment LCG-2_6_0 on SL 3.0.x, managed by Quattor & yaim SE (dcache) w/ access to entire DESY data space 200 CPUs by end of '05 RB, BDII, PXY, RLS; VOMS soon VOs managed: hone, hermes, zeus, herab, ildg, ilc/calice, dcms, baikal, icecube VOs supported: atlas, cms, dech

4 Connectivity & Infrastructure 1 Gb/s ET XWIN connection in 2006 (Hamburg site) bandwidth initially 300 or 600 Mb/s, according to needs VPN connection to GridKa (p2p) likely 10 Gb/s in 2006 Zeuthen site will hopefully get 1 Gb/s p2p to Hamburg additional machine room of 300 m2 will be ready in spring power/ups/cooling prepared same monitoring as HERA infrastructure

5 GRID Development International Lattice Datagrid will allow for worldwide sharing of data from lattice QCD simulations within a grid-of-grids DESY coordinates deployment of an LCG-based datagrid for lattice groups in France/Germany/Italy Work is done in cooperation with ZAM (Juelich), ZIB (Berlin) DESY implements and will maintain a metadata catalogue for storing XML documents All Grid components exist (at least at prototype level), further work needed for reaching production level Key issue for next year: address interoperability with other ILDG grids

6 GRID Use: Increasing H1, Zeus Monte Carlo production ILC simulation data exchange ZEUS MC production 05/06 (by H. Stadie et al.) H1 MC production (by M. Karbach et al.)

7 Plain Old Computing Platforms supported Windows Desktop, Login, CAD, Services slowly increasing use for number crunching Linux Desktop, Login, Farms, Services Solaris Services, still some login facilities working on Solaris 10 (still SPARC only) 4 production systems w/o AFS 4 test systems (OpenAFS 1.4-rc6) no OS X support, no plans

8 Windows migration to win.desy.de domain (XP, 2003) complete some 300 systems left in DESYNT (accelerator controls, or hardware not sufficient for new OS) 3300 user accounts, 2950 systems (2430 RIS installs) daily online: ca % of XP clients with SP2 2-node clusters or simple failover for most services storage, web, SQL, license management 8 TB storage, initial home quota 500 MB Exchange 2003 cluster (migration in April '05) 4 HP blades, 2 TB Storage (HP MSA 1000)

9 Exchange DESY 2 TB disk space 9 x 146 GB data 8 x 72 GB TX-logs

10 Exchange ,000,000 1,000,000 distribution of mailbox sizes (October 2005) Mailboxes: ~2800 Exchange ~2200 used ( delivered to Exchange) delivered to UNIX-cluster: ~3300 mailboxes size in KB 100,000 address management via DESY-registry 10,000 Quota: 1,000 only informational s planned: 200 MB standard MB "power-users" 1 GB special mailboxes (shared) 2 GB hard limit 10 due to mailbox moves max. allowed PST file size 1 virus check by GroupShieldExchange 5.2 mailboxes

11 Windows: Management MS Premier Support since October SUS -> WSUS for updates & hotfixes see presentation by Reinhard Shavlik for servers patch management Insight Manager for driver updates McAfee VirusScan Enterprise 8.0i NetInstall for application software ongoing work advanced notebook support extension of terminal services

12 Windows: Terminal Services Zeuthen has run a 2-node cluster for a few years for Linux desktop users Citrix Metaframe advantage: published applications increasing use of RDP simpler to use and support, rdesktop improving no NetInstall (to come soon) now 2nd cluster for mail & internet access by windows users with SAP access, due to security considerations RDP only Hamburg now has a 2-node pilot system RDP only, with NetInstall

13 Linux default system: SL3 i386 or amd64 (farm nodes & servers) SL4 for some servers, notebooks need stable AFS client for most systems no widespread adoption in HEP? yet? SL5 in time for LHC? many DL5 systems left many systems w/o central support (usually debian) Quattor working group used for GRID nodes (alone or with yaim, depending on type) production cluster: migration to Quattor 1.1 development of a template structure for general use

14 Batch (Zeuthen Shared Farm) Resources (all running SL 3.0.5) 65 dual Opteron SUN V20z, GHz, 4-8 GB, 64-bit SL 50 dual Xeon SUN V65x, 3.2 GHz, 2 GB + 50 dual Pentium III white boxes, 800 MHz, GB SUN Grid Engine Version 6u4 in production since June fully kerberized (K5), including AFS support ticket/token handling by arcx/arcxd capacity assigned to projects using share tree & fair share 4700 jobs/day, avg. duration 30', V20/V65 utilization 80% running smoothly after bugs reported to SUN fixed Grid integration by David McBride tested once

15 Parallel Computing apenext massively parallel supercomputer optimized for Lattice QCD 2 large prototypes running physics codes 1st of 3 machines shipped to DESY this week 4 machines = 3 TFlops at DESY in January ongoing development of Tao & C compilers, assembly optimiser, operating system PC clusters 16 & 32 nodes dual Xeon, Myrinet 16 nodes dual Opteron, Infiniband

16 Tools RT: free request tracker (BEST PRACTICAL) used for user requests to uco and a few other things interfaces: web, mail, cli run in Hamburg, used by both sides both shared and dedicated queues complete success Wikis: several existing or planned Zeuthen looked at MediaWiki & MoinMoin now deploying MoinMoin (ACLs) very successful application: minutes PMDF -> Sympa for mailing list management soon
