  2. GridKa SC4 Tier2 Workshop – Sep. 18 - 19, 2006 - 2 Warsaw Tier 2 center - overview • Resources hosted by ICM - Interdisciplinary Centre for Mathematical and Computational Modeling (main computing facility of Warsaw University) • Site name in GOC DB: WARSAW-EGEE • Domain .polgrid.pl • Main services: helpdesk,ce, se, cms-vo • Resources funded by National Research Agency, manpower also by EGEE

  3. GridKa SC4 Tier2 Workshop – Sep. 18 - 19, 2006 - 3 Resources at ICM • 260 AMD Opteron CPUs in Sun Fire V20z and V40z nodes • 15 TB of disk space

  4. GridKa SC4 Tier2 Workshop – Sep. 18 - 19, 2006 - 4 Resources at ICM (continued) • 180 AMD Opteron 252 CPUs + 44 AMD Opteron 275 (dual core) CPUs = 268 effective CPUs (about 400 kSi2k), all in Sun Fire V20z and V40z nodes • 2 GB of memory per CPU and 73 GB SCSI HDD per node • 15 TB of disk space in SATA HDDs connected to 4 Sun StorEdge 3500 RAID arrays • Storage currently served via Classic SE (3.5T) & DPM (3.5T + 3.5T dedicated for CMS) • Gigabit ethernet for internal communication • Full IPMI management & remote monitoring • Currently 50% of resources allocated for CMS (soft limit and may be changed)

  5. GridKa SC4 Tier2 Workshop – Sep. 18 - 19, 2006 - 5 WARSAW – EGEE accounting data • Scheduler setup (FairShare, MaxProc): • CMS (50%, 200) • Compass (20%, 100) • LHCb (10%, 50) • VOCE (10%, 50) • Atlas ( 3%, 10)

  6. GridKa SC4 Tier2 Workshop – Sep. 18 - 19, 2006 - 6 Network infrastructure • Current situation • Stable 1 Gbit/s from Warsaw to Poznan (over PIONIER network, dedicated VLAN for scientific projects) • 2.4 Gbit/s from Poznan to GEANT • Planned for near future • There are also plans to connect Tier2 VLAN directly to DFN with 2*1 Gbit/s dedicated connection (from Poznan).

  7. GridKa SC4 Tier2 Workshop – Sep. 18 - 19, 2006 - 7 Network infrastructure (continued) PIONIER

  8. GridKa SC4 Tier2 Workshop – Sep. 18 - 19, 2006 - 8 Software installation • User support for the Central European ROC (helpdesk.polgrid.pl), already connected to GGUS • Currently standard Glite 3.0 installed on the cluster • CE (ce.polgrid.pl) • Classic SE (se.polgrid.pl) • Testing services: DPM SE (setut.polgrid.pl) and CMS VO box (cms-vo.polgrid.pl) • Planned for nearest future • Finish storage reorganization • Complete CMS services installation
