  1. HPCx:an Overview Dr Arthur Trew Director, EPCC

  2. what is HPCx? • HPCx is the latest in a series of HPC services for UK academia • £52.9M from UK Research Councils • £1M from IBM for HPC R&D at EPCC • £600k from IBM for Life Sciences outreach • UoE HPCx Ltd runs the contract • wholly-owned subsidiary of the the University • CCLRC, EPCC and IBM are subcontractors • EPSRC’s objectives for the procurement were • “ to deliver the optimum service resulting in world-leading science” • “ address the problems in scaling codes to capability levels (512+)” • … so, the challenges we face are to • support change from capacity to capability • develop more scalable codes • science support is the key to success IBM Team Talent Meeting

  3. the story so far • Phase 1 service started on 9 December 2002 • The first year was extremely successful • CPU utilisation grown to >80% • 25+ user groups, ~350 users IBM Team Talent Meeting

  5. looking forward • the Phase 1  Phase 2 upgrade most risky part of the project • new hardware, colony  federation • new software, PSSP  CSM • EPSRC has funded small Phase 2 development machine • so, the support teams are more prepared • but switch performance is (currently) poor • … and unlikely to satisfy EPSRC • termination is unlikely but the relationship with EPSRC could be less cordial post-Phase 2 IBM Team Talent Meeting
