3 © Crown copyright Met Office MONSooN Met Office / NERC Superco(o)mputer Nodes “To provide a shared supercomputing service in an environment within which collaborative projects between NERC and Met Office can be performed. The joint service is being provided to enhance collaboration between NERC and Met Office researchers and improve their ability to pull-through environmental science more rapidly.”

7 © Crown copyright Met Office......the MONSooN project has been held up as a particularly good example, providing a joint supercomputing system that allows scientists to collaborate on research into modelling issues. Biggest Issue? Security!!

10 HPC: For Techies! CPUs (or Cores) per node32 Peak Performance per node (GFLOPS)960 Number of Nodes (Compute/Non-compute)160 (149/11) LINPACK Performance (TFLOPS)113 Number of CPUs/Cores5120 Total Memory (TBytes)10.2 Total User Disk (SAS/SATA)(TBytes)490 (300/190) MFLOPS/Watt (LINPACK)370

11 © Crown copyright Met Office Issues (1) - Security Met Office has MoD Accreditation; impacts all aspects of the organisation (e.g. BBC contract) Users of MONSooN: Cleared and uncleared staff Requirement of Project: “Treat all users the same” Lack of clarity over all user requirements Some unwieldy outcomes, not meeting “true” user requirements Two-stage login, password plus a SecureID token/PIN combination – awkward for file copies, UMUI, etc Inactivity timeouts – 30 minutes IP Lockdown – Only ‘known’ hosts can access, restrictive to mobile users A number of changes modifying the system to make access easier. (e.g. SSH Proxy Servers)

12 © Crown copyright Met Office Issues (2): Science Unusual to have visibility of upcoming projects Existing Projects don’t always run to schedule; have trouble predicting their ongoing requirements. Project plans often change... Tendency to evolve organically Not as fully featured as an internal Met Office system Disparate organisations with differing priorities, funding and schedules. Scientific Collaboration – at the working level – doesn’t appear encumbered by national or funding boundaries.
