HEPiX Spring 2012 Highlights: Advancements in HEP Site Management and IT Infrastructure

The HEPiX Spring 2012 meeting, held in Prague, Czech Republic, gathered 97 participants to discuss key topics in High Energy Physics site management. With a focus on IT infrastructure, the agenda was filled with insightful presentations on business continuity, energy efficiency, and emerging technologies such as cloud computing and virtualization. Attendees included service managers, sysadmins, and IT professionals from a mix of large and small institutions. The forum emphasized collaboration and shared learning, reflecting 20 years of HEPiX’s commitment to supporting the HEP community.

  1. HEPiX Spring 2012Highlights HelgeMeinhard CERN-IT GDB 09-May-2012

  2. HEPiX • 20-years old, self-organised forum of people involved in site management in HEP • More service managers/sysadmins than IT managers • Open to anyone interested • Further information, including archives of past meetings: http://www.hepix.org/ • Mix of large and small sites, many involved in WLCG • Present recent work and future plans, share experience, advise managers • 1-week meetings twice per year • Spring in Europe, autumn typically in North America • Working groups on specific issues

  3. Spring 2012 Meeting (1) • Held 23 – 27 April at the Czech Academy of Sciences, Prague, Czech Republic • Tier 2 centre in LCG • Excellent local organisation • Prague: town with a very rich history, impressive architecture, good beer, rich food, … • Sponsored by a number of companies: Dell, WD, Netapp, IBM; EMC2; SGI, Bull, Proact

  4. Spring 2012 Meeting (2) • Format: Pre-defined tracks with conveners and invited speakers per track • Extremely rich, interesting and (over-)packed agenda • Novelty: three weeks before the meeting, the agenda was full – abstracts needed to be rejected, accepted talk slots shortened • New track on business continuity, convener: Alan • Judging by number of submitted abstracts, most interesting topic was IT infrastructure (17 talks!). 10 storage, 7 Grid/cloud/virtualisation, 6 network and security, 5 computing, 4 business continuity, 3 miscellaneous… plus 22(!) site reports • Full details and slides:http://indico.cern.ch/conferenceDisplay.py?confId=160737 • Trip report by Alan Silverman available, too • Linked to Indico page above

  5. Spring 2012 Meeting (3) • 97 registered participants • Vancouver Oct 2011: 98; GSI May 2011: 84 • 74 talks • Vancouver Oct 2011: 55; GSI May 2011: 54 • HEPiX Board meeting: new European co-chair elected (HM) • Succession of Michel Jouvin, who stepped down following his election to become GDB chair • 4 candidates from 3 European institutes

  6. Topical Highlights (1) • Business Continuity: New track, of interest not only to large (T0/T1) sites • Presentations by FNAL, CERN, RAL • AGLT2 also thinking about it… • Continuous interest in infrastructure • Energy efficiency will be a dedicated topic in future meeting • Fabric management changing in many places • CERN: AI; many labs moving to Puppet; Quattor also healthy; some sites moving monitoring away from Nagios

  7. Topical Highlights (2) • Batch scheduler • Many sites report scaling issues with PBS etc. • Condor and Slurm on the rise • xGE introduced in some places – forum created for exchange between scientific sites • Cloud computing on the horizon of realism • Private clouds: Openstack, OpenNebula • Storage: dynamic federations; what comes after RAID • Networking and security: identity federations, IPv6, computer security

  8. Working Groups Virtualisation: very active, reports regularly given IPv6: idem Storage: activities in bursts, coming up soon Benchmarking: same status as in Vancouver

  9. HEPiX Future • Next meetings: • Autumn 2012: Beijing (hosted by IHEP); 15 to 19 October • Spring 2013: Bologna (date to be decided) • Autumn 2013: Interest by U Michigan, Ann Arbor, US • Large number of participants and talks this time round • Interest for a North-American meeting in 18 months’ time • Interest by LCG to use HEPiX as advisory body for site matters • HEPiX appears to be very healthy
