An administrative change
NinJo
NinJo
• Deployed operationally Dec 2006
• 4 data types:- Observations- Model data (HIRLAM)- Radar- Satellite
• In parallel with old system
NinJo
• Lightning data, more models added
• Experiences (subjective)– Younger users more likely to use NinJo– Good super users gives better acceptance– Don’t try to limit the users

New supercomputer
Supercomputer
• Replacing the current NEC SX6 with a Cray in 4 steps:– An XT4 as an ”early migration system” in parallel
with the NEC has been installed– The XT4 takes over all applications and the NEC is
closed down (scheduled 16 July)– The NEC is disassembled and a Cray XT5 put in
instead– The XT5 to be turned on late october and take over
all applications before the end of the year
Cray XT: Homogenous Architecture, scalable nodes

Supercomputer
• Software• - loginnodes have full SuSE Enterprise Linux• - compute nodes have Compute Node Linux (speciel
kernel and version of SuSE)• - third party compilers, amongst others PGI,
PathScale, Gnu GCC
• Cost• - Cray XT4/5, 6 million €• - refurbishing of machine hall ~450.000 €• - other costs ~65.000 €

Road Weather
Information System
Road Weather Information System
• Once it was MFC C++
• Then it became JavaScript
• But that was too slow so…
• Now reimplemented in pure Java, using Java WebStart for updgrading
The Challenge:
Provide complex meteorological information Provide complex meteorological information
in a non-complex formatin a non-complex format

Graphical Production
System
Graphical Production System
• So far based on a locally developed program
• Written in MFC C++, no further development
• Can only generate pixel-based images
• Does not scale very well
• New product = new extraction + new graphics + new dissemination
Graphical Production System
• Requirements for new system– Based on common standards– Deliver both pixel and vector graphics
• Illustrator CS-series chosen
– Be scalable– Common products for many customers
