  2. HEPiX – www.hepix.org • Global organisation of service managers and support staff providing computing services for HEP community • WLCG Tier-0, Tier-1s, some Tier-2s regularly attend • More sites very welcome – subscribe to hepix-users • Workshops of one week twice per year • Exchange of experience, reports on recent work, work in progress, future plans • Usually no showing-off Helge Meinhard (at) cern.ch

  3. HEPiX Spring 2013 • April 15 – 19 at CNAF, INFN, Bologna (IT) • Very well organised, rich programme • Coincided with 50th anniversary of CNAF • 83 registered participants • Europe: 69, North America: 8, Asia: 5, Australia: 1 • Administrative hurdlesand illnesses prevented even better participation • 70 presentations from 40 institutes • 3 BoF sessions (OpenAFS/IPv6, CMDBuild, Energy efficiency) • Many discussions after talks and off-line • Programme and complete slides:http://indico.cern.ch/event/hepix-spring2013 Helge Meinhard (at) cern.ch

  5. Tracks and Trends • Computing (5 talks); networking and security (7 talks); IT infrastructure (21 talks); grids, clouds, virtualisation(5 talks); storageand file systems (10 talks); 17 site reports • Batch system reviews everywhere • UnivaGridEngine seems to take the lead • WNs with HT • Broad use of cloud services & virtualisation • Private clouds almost everywhere (mostly Openstack) • Idle VM detection (FNAL), EC2 spot pricing (BNL) • Puppet taking the lead for configuration management • But: no monoculture expected • Interest in Ceph for VM storage • At an early stage everywhere • Federations: identity, federated clouds etc. • Long-term data preservation • Non-x86 platforms Helge Meinhard (at) cern.ch

  6. HEPiX Working Groups (1) • IPv6 • IPv4 address shortage becoming a serious issue soon (including at CERN!) • Support for IPv6-only worker nodes needed by 2014 (or soon after) • Distributed testbed has been set up, more and more sites joining, constant testing (file transfer) • All LHC experiments participate in WG as well • Tools & Software Survey, “problematic” applications identified • All batch schedulers, OpenAFS, ActiveMQ, … • Base platform for testing is SL5 • 2013 goals: increase participation, agree on dual-stack services, test them Helge Meinhard (at) cern.ch

  7. HEPiX Working Groups (2) • Storage • WG terminated • Summary report at next meeting in autumn • Benchmarking • No new SPEC benchmark • Starting to re-evaluate (dis-)agreement between applications and benchmark(used for purchases) • Configuration Management • New WG led by Ben Jones (CERN) and Yves Kemp (DESY) • Batch schedulers • Not a formal working group, but rather a collection of material on the Web Helge Meinhard (at) cern.ch

  8. OpenAFS/IPv6 BoF Session • Many sites regard AFS as one of their core services, value its robustness and plan to continue using it in the future • Various options to deal with the IPv6 situation were discussed, but the lack of IPv6 support is not regarded as a burning issue (at least right now) • The need to gather more information was identified (use cases, traffic maps, prices for an implementation, …) to take an informed decision (before or at next HEPiX) • Peter van der Reest (DESY) and Arne Wiebalck (CERN) to follow up Helge Meinhard (at) cern.ch

  9. Next HEPiX meetings • Fall 2013: U Michigan, Ann Arbor, MI, USA • October 28 – November 1 • Spring 2014: LAPP Annecy, France • May 19 – 23 • Fall 2014: Following up on various ideas, no firm decision yet Proposals are always welcome… Helge Meinhard (at) cern.ch

  10. Final Words Hope to see many of you in Ann Arbor (28-Oct to 01-Nov) Helge Meinhard (at) cern.ch
