IT Infrastrukture

General

Server room

The Institute has a well equipped, modern IT infrastructure. In a small , air-conditioned server room, 11 servers work, of which ten runs on Linux operationg system. Half of the server is required for meteorological special tasks.

More than 60 workplaces are equipped with computers. In addition to that, there is a small pool room with 5 computers as well as printers and scanners. Approx. 15 measuring computers for controlling measuring systems and recording data as well as serveral laptops complete the IT equipment. All the computers are wired structured. For Linux computers, data and user information are stored centrally on a server and partly backed up daily.

 

NinJo Workstation

Server for the NinJo Workstation

The program NinJo Workstation serves for to the visualization and treatment of meteorological data. It is developed by the National Meteorological Service of Germany, the National Meteorological Service of Switzerland, the National Meteorological Service of Denmark, and the National Meteorological Service of Canada and is used internationally. This program causes for a network load of about 100 GB every day and holds constantly about 600 GB of data.

Nvidia 3D Vision technology

3D visualization of a dust devil

The lecture root of the institute is equipped the Nvidia 3D Vision technology. This makes it possible to interactively view computer animation such as the turbulent flow around buildings and vortex dynamics in the atmosphere with the help of 3D technology.

GPU Server for parallel computing

One server of the institute is equipped with two of the late 2013 published graphics accelerator cards Nvidia Tesla GPU K40 and is set up at the data center LUIS of the Leibniz University Hannover, better known under the old name RRZN, and is also usable by other scientists of the university. Members of the Palm project work together with the employees of the compiler manufacturer Portland Group.

Supercomputing at IMUK

The North-German Supercomputing Alliance (Norddeutscher Verbund zur Förderung des Hoch- und Höchstleistungsrechnens – HLRN) operates one of the fastest solid parallel computers in Germany. The system with more 56.000 processor cores represents an important contribution for the promotion of science and research in the northern Lands of the Federal Republic. The HLRN III consist of two identically constructed Cray XC30, which are developed at the RRZN (regional computing centre Lower Saxony) in Hanover as well as at the ZIB (Konrad Zuse center) in Berlin.

One of the main users of the HLRN-III system is the Institute of Meteorology and Climatology, which uses the supercomputer for computing-time consuming simulations of the atmospheric border layer on several thousand processor cores (see PALM working group).
