  1. HPCxPower for the Grid Dr Alan D Simpson HPCx Project Director EPCC Technical Director

  2. HPCx Overview • UK’s major HPC facility, primarily funded by EPSRC • £53M/6 year contact awarded to UoE HPCX Ltd • wholly-owned subsidiary of University of Edinburgh • work subcontracted to CCLRC (DL), EPCC and IBM • Largest academic supercomputer in Europe • doubling in performance every 2 years HPCx

  3. HPCx Objectives • Deliver capability computing for world-leading science • Capability Computing • jobs which use a significant fraction of the resource, eg, at least 512 CPUs • Collaboration between HPCx and users through the Terascaling process • Maximise benefits to the UK’s computational science and engineering community • Forging links between HPC and e-Science • High quality support is the key to success HPCx

  4. Partnership • EPCC and CCLRC • are partners in C3ES (Consortium for Capability Computing and e-Science) • underpinned by MoU between UoE and CCLRC • combines Europe’s foremost academic HPC, e-Science and technology transfer centres • virtual organisation facilitated by Access Grid • significant experience of: • operating national HPC services • developing capability applications • the strongest UK partnership ever to support scientific computing HPCx

  5. Users Outreach Applications Support Life sciences New applications Helpdesk Training Liaising with users Terascaling Capability applications Scalable algorithms Performance optimisation Software Engineering Underpinning technology Grid/e-Science Systems & Networking Flexible and responsive capability computing service Smooth transitions between phases Technology Virtual Organisation Dual-centre functional support teams HPCx

  6. HPCx Utilisation • successful first 9 months • >75% utilisation for last 6 months • capability usage has increased to 35% HPCx

  7. HPCx and the Grid • Key responsibility for Software Engineering team • led by Dr Stephen Booth • who is also responsible for EPCC’s Grid operations • HPCx is committed to support access via Grid • currently provided through Globus 2 • Globus 3 support when appropriate • HPCx is key part of UK collaboration with Extensible Teragrid Facility project in the US • promoting UK science on the world stage HPCx

  8. ETF Collaboration • Focus is exploiting unique features of Grid + HPC systems for capability computing • `HPCy-class’ applications • Initial experiment planned for SC2003 • RealityGrid computational steering • HPCx is major compute resource • Current challenges are: • network bandwidth • lack of direct network connections to compute nodes • developing port-forwarding software to allow Globus IO connections to batch jobs HPCx

  9. Summary • HPCx builds on significant complementary experience at EPCC and DL • Very successful start • …with capability usage already up to 35% • Committed to e-Science and the Grid • strong links with NeSC and CCLRC e-Science Centre • ETF experiment at SC2003 • HPCx is focussed on capability computing • world-class service for world-class research HPCx
