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.”

......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?

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)

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.
