Wednesday 9th May - Agenda
Introduction (Michel Jouvin)
• GDB summary needed. Plan to put notes in wiki linked to agenda.
• Encourage cross-VO T2 deployment of perfSONAR.
TEG next steps (Ian Bird)
• The TEGs as such (big working groups) have finished. Still work to be done.
• Further discussions at CHEP – including future of DPM.
• Deployment of glexec becomes a priority (tarball is not a solved problem)
CRSG report to the C-RRB (Ian Bird)
• Higher rates and parking data plus more analysis means slightly more resources needed (ALICE, ATLAS and CMS)
• LHCb have a revised charm physics program
• A lot more pile-up in 2012
• Use of high-level trigger farms to help with processing
• T2 installed capacity still an issue – REBUS will be used. Need to check the figures published for each site.
LHCOPN/ONE status & directions (John Shade)
• LHCOPN functioning well. Alarms: https://cclhcopnmon.in2p3.fr/LHCOPN/report/.
• perfSONAR-PS and MDM interoperability not tested. Jason Zurawski offering workshop on toolkit for site managers – any interest?
• L3VPN operations https://twiki.cern.ch/twiki/bin/view/LHCONE/WebHome.
• Routing policies important – symmetric paths
• OpenFlow as a protocol. TRILL/SPB for resilience (replace P2P links)
• PerfSONAR is a dormant setup with some selected core sites/points involved with regular testing.
• Encourage sites to install – guidelines in twiki. Sites need to setup alarms for themselves.
Federated Identity Management for HEP (David Kelsey)
• Remove the ID management from the service (use single sign-on). Adding an attribute authority (e.g VOMS) adds complexity
• Spans many communities not just HEP – common requirements being discussed (e.g. open standards, attribute aggregation) including operational ones like traceability.
• Research communities are to perform a risk analysis of using IdM.
Procedure to follow for proposed new T1 sites (Ian Bird)
• Policy document linked from agenda – discussed in 2011
• Requires expt. Support and balance against high-standards of existing T1 services.
• Prepare detailed plan. Follow tests and meet required service levels. Reach full status after about 1 year and Overview Board approval
HEPiX (Helge Meinhard)
• 23rd-27th April. Over-packed agenda. New track on business continuity
• Fabric management changing. Many labs moving to puppet. Quattor healthy. Some sites moving monitoring away from Nagios.
• Cloud computing on the horizon of realism (Openstack and OpenNebula)
• Working groups (virtualization; IPv6; Storage; Benchmarking)
WLCG workshop (Jamie Shiers)
• wlcg workshop mailing list
• Draft agenda now online
Virtualized WNs and Clouds
HEPiX Virtualisation WG report (Tony Cass)
• Set up to facilitate the instantiation of user-generated VM images at HEPiX sites
• Image endorsement – technical constraints and policy discussed
• Framework for endorsers to publish has been developed
Update on WNosDeS (Davide Salomoni)
• Worker nodes on demand service: http://web/infn.it/wnodes
• Integrates Grid and Cloud provisioning through virtualization
• Upcoming – dynamic VLANs
EGI Federated Clouds Task Force (Matteo Turilli)
• Why? Users keen on personalized environments
• Federation testbed now live
• https://wiki.egi.eu/wiki/Fedcloud-tf:FederatedCloudsTaskForce
VM contextualization and image cataloguing in ATLAS (Fernando Megino)
• Why? Some sites support multiple VOs with different needs. To be ready for when cloud resources are offered.
• Work ongoing over 1 year. Still manual steps. Currently use CERNVM.
• Contextualization desired for Gangli and Condor installs.
• Comment: Getting credentials in fine but concern about site settings for syslog etc. being overridden. Condor should be via CVMFS.
The next meeting is on 13th June. David is the T2 rep. There is a draft agenda in indico.
