18th Workshop on high performance computing in meteorology

A set of gems is making its round: the dyamond simulations are
aiming for gaining experiences in high resolution global
modelling. The aim is to reach, in the beginning, 40 days of
roughly 2.5 km grid size global simulations.

This type of simulations poses a couple of challenges: usable
boundary conditions, output data size, output data handling,
sustainable computer resource usage, and a seriuos amount of
patience for everybody involved.

For setting up and initial debbuging simulations of this kind
tools have to be improved in their memory scalability. The range
of applications starts from preprocessing tools, the respective
data sets, the required visualization tools allowing gridpoint level
access to data and new visualization algorithms.

We will present an overview of our solutions.
