CSCS Status Peter Kunszt Manager Swiss Grid Initiative CHIPP, 21 April, 2006

Status: Personnel Current status § Sysadmin by CSCS FUS group – organized internally by FUS § PK as official LCG CHIPP contact Hiring more people (1, maybe 2) § Interviews are being conducted § Last interview to be held on Monday next week § Expected start date for new person: Aug 1 st latest User Support § Formalization of interactions within/outside CSCS § All outside contacts through Grid Team (PK) § As necessary, infrastructure items handed down to CSCS FUS group using the internal Request Tracker § CSCS Full member of the DECH federation support § User support through GGUS, see: https: //gus. fzk. de/pages/email_interface_info. php § Only for Phoenix directly through project-lcg-cscsgrid@cern. ch CHIPP, 21_04_2006, P. Kunszt

Status: Phoenix Upgrades § Cluster has been upgraded to LCG 2. 7 § Attempted to upgrade the kernel to 2. 6 – failed due to network and storage hardware driver problems; solution has been found but not applied yet § Upgraded to the latest 2. 4 kernel Extensions § LCG 2. 7 introduced new services § § DPM – migration from our ‘classic SE’ has been successful LFC – not installed yet; probably next week VOBoxes dedicated to each VO FTS – not necessary at CSCS for now, see below § We ordered 5 additional Dell Service nodes as a stop-gap solution until the end of the year § Dedicated VO Boxes for Atlas, CMS, LHCb possible § LFC node § Separation of UI and MON, avoiding ‘service overload’ CHIPP, 21_04_2006, P.

High Bandwidth Networking - SWITCH CHIPP, 21_04_2006, P. Kunszt

Status: Networking Currently 1 Gb available from CSCS through SWITCH § 10 Gb possible especially through new link via Domodossola/Brig § Current usage at 20 Mb (!) so CSCS does not see any need to upgrade § Switches for 10 Gb are here but not installed yet (no need) Dedicated Links § Possible to have dedicated bandwidth (lambda lightpaths) to CERN § All GEANT connections are through the CERN POP § GEANT can also provide dedicated links to FZK, IN 2 P 3, CNAF, RAL § Pricing unclear – waiting for SWITCH personnel to get back from vacation § Need unclear – suggest to run SC 4 exercise first, see below CHIPP, 21_04_2006, P. Kunszt

Status: Service Challenge 4 SC 4 starting! § § Contacts to FZK established, communication very good First tests of DPM successful – single-file transfer rate between FZK and CSCS is about 50 MB/s The channels FZK-CSCS and CSCS-FZK are now available on the FZK FTS server. The endpoints of the server are: https: //192. 108. 45. 172: 8443/fzk-fts/glite-data-transfer-fts/services/File. Transfer. Stats https: //192. 108. 45. 172: 8443/fzk-fts/glite-data-transfer-fts/services/Channel. Management 1 GB/1 MB files have been transferred in both directions ok. Thorough testing of the throughput starting today/next week So we are one of the first Tier 2’s to join As declared, LCG pre-service == SC 4 so it‘s important to be part of it early. § § Considerations § Bottlenecks will probably not be on the network § § § Where the network traffic flows through to other Tier 1 s (even if through CERN) is irrelevant, importance is on § § § Storage bandwidth Firewalls Scaling wrt amount of data (storage bandwidth) Locality of access SWITCH has a Performance Enhancement Response Team to diagnose network problems, see http: //www. switch. ch/network/pert/ CHIPP, 21_04_2006, P. Kunszt

Status: EGEE CSCS is now official member of EGEE-II § All legal issues have been sorted § Contract has been signed § We’ll get a total of 184’ 000 Euros for 2 years Involvement § SA 1 – infrastructure: running the cluster, participate in GGUS § NA 3 – training: participate in training and education § NA 4 – applications: support of application ‘gridification’ Mandate is not only HEP § NA 4 involvement in Biomed, Chemistry, Earth sciences § Suggestion to extend the Phoenix cluster with 15 -20% so that the non-HEP VOs can be supported, funding from CSCS/EGEE CHIPP, 21_04_2006, P. Kunszt

Status: Portal Installation of a P-Grade portal at CSCS almost complete § alprose 01. projects. cscs. ch will run the portal, the installation is being done. § The portal will be hooked up to the LCG/EGEE environment for people to use/test § It is an interesting and potentially useful extension to the running services, we had interests expressed by other people (ETHZ, Uni.
