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

CHIPP, 21_04_2006, P. Kunszt 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:  Only for Phoenix directly through

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. Kunszt High Bandwidth Networking - SWITCH

CHIPP, 21_04_2006, P. Kunszt Status: Networking Currently 1Gb available from CSCS through SWITCH  10Gb possible especially through new link via Domodossola/Brig  Current usage at 20Mb (!) so CSCS does not see any need to upgrade  Switches for 10Gb 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, IN2P3, CNAF, RAL  Pricing unclear – waiting for SWITCH personnel to get back from vacation  Need unclear – suggest to run SC4 exercise first, see below

CHIPP, 21_04_2006, P. Kunszt Status: Service Challenge 4 SC4 starting!  Contacts to FZK established, communication very good  First tests of DPM successful – single-file transfer rate between FZK and CSCS is about 50MB/s  The channels FZK-CSCS and CSCS-FZK are now available on the FZK FTS server. The endpoints of the server are:  1GB/1MB files have been transferred in both directions ok. Thorough testing of the throughput starting today/next week  So we are one of the first Tier2’s to join  As declared, LCG pre-service == SC4 so it‘s important to be part of it early. Considerations  Bottlenecks will probably not be on the network  Storage bandwidth  Firewalls  Where the network traffic flows through to other Tier1s (even if through CERN) is irrelevant, importance is on  Scaling wrt amount of data (storage bandwidth)  Locality of access  SWITCH has a Performance Enhancement Response Team to diagnose network problems, see

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  SA1 – infrastructure: running the cluster, participate in GGUS  NA3 – training: participate in training and education  NA4 – applications: support of application ‘gridification’ Mandate is not only HEP  NA4 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  alprose01.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, UniGE)
