  1. SIRE Group Brunel University, Department of Electronic and Computer Engineering, Uxbridge, UB8 3PH, UK Dr Peter R Hobson C.Phys M.Inst.P

  2. SIRE Group computing • HEP computing plus image processing and digital holography. • About 15 local users • GRID computing for particle physics and other computationally intensive applications. • Windows 2000 or RH 7 or 8 on the desktop • Email, networking provided centrally (Unix servers at present but migrating to full W2000) • No PPARC funded system management effort HEPSYSMAN, 28 April 2003

  3. SIRE Group facilities • Small amount of desktop power • New cluster being installed (SRIF 1) in our new “BITLab” • 64 Dual hyper threading Xeon nodes • 2 Gb memory per node • Dual 1-Gbit network connectivity between nodes • Part of the London Distributed Tier-2 centre • Recent success with SRIF 2 funds • 128 more nodes to come • All cluster computing resources shared with a number of other non-HEP users. HEPSYSMAN, 28 April 2003

  4. Local challenges • All networking controlled centrally • Presents a real challenge for GRID computing, videoconferencing etc. • Centrally managed firewall • Central responsibility for certificate authentication • Efficient and flexible management of the Tier 2 • Mixed user community with special needs • HEP computing • 3D visualisation • Video walls • Ray tracing engines etc. • Coordination of new resources HEPSYSMAN, 28 April 2003

  5. Summary • Major changes taking place • Huge (for us) increase in computing power and management complexity • No increase in funded personnel • New mixed user environment • Changes in the central computing provision • Our “BITLab” is a University flagship project, so it had better work well this Autumn!
