The Atmosphere, Ocean and Climate group (atmosphere and ocean modeling) has a long experience of atmospheric modeling based on a number of cluster for over a decade, using message passing interface and portable batch system. The group currently operates three clusters.


The older cluster (VORTEX) established in 2005, is used in Numerical Weather Prediction, the cluster includes 16 computers (160 cores in total). In 2011 the group established a second cluster (TORNADO) necessary to run the EC-Earth Global Earth System Model, this system includes 26 computers (576 cores). Most recently, the group acquired a third cluster (NIMBUS), whose system is essential for the new needs of high-resolution dynamical downscaling of climatic fields, for seasonal, decadal predictability and climate scenario studies, and for the simulation of atmosphere-ocean coastal processes. This cluster includes 21 computers with a total of 848 cores.
