CSCS Status

1
CSCS Status

• Peter Kunszt
• Manager Swiss Grid Initiative
• CHIPP, 21 April, 2006

2
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 1st
  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_at_cern.ch

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

High Bandwidth Networking - SWITCH
5
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

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 https//192.108.45.1728443/fz
  k-fts/glite-data-transfer-fts/services/FileTransfe
  rStats https//192.108.45.1728443/fzk-fts/glite-
  data-transfer-fts/services/ChannelManagement
• 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 Tier2s to join
• As declared, LCG pre-service SC4 so its
  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
  http//www.switch.ch/network/pert/

7
Status EGEE

• CSCS is now official member of EGEE-II
• All legal issues have been sorted
• Contract has been signed
• Well get a total of 184000 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

8
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)
