Warsaw Tier 2 Site

Warsaw Tier 2 centre - overview • Resources hosted by ICM - Interdisciplinary Centre for Mathematical and Computational Modelling (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

Resources at ICM • 180 AMD Opteron 252 CPUs + 44 AMD Opteron 275 (dual core) CPUs = 268 effective CPUs (about 400 k. Si 2 k), all in Sun Fire V 20 z and V 40 z 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 Stor. Edge 3500 RAID arrays • Storage currently served via Classic SE (3. 5 T) & DPM (3. 5 T + 3. 5 T 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)

WARSAW – EGEE accounting data • Scheduler set-up (Fair. Share, Max. Proc): • • • CMS Compass LHCb VOCE Atlas (50%, 200) (20%, 100) (10%, 50) ( 3%, 10)

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 also plans to connect Tier 2 VLAN directly to DFN with 2*1 Gbit/s dedicated connection (from Poznan).

Network infrastructure (continued) PIONIER

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 •
