Niflheim Linux v.6 supercomputer cluster

This Wiki contains Getting_Started information and various technical information about Niflheim version 6.

For the previous Niflheim version see


The Niflheim Linux cluster supercomputer is installed at the Catalysis for Sustainable Energy (CASE) center at the Technical University of Denmark (DTU).

Niflheim's present compute resources consist of xxx CPU cores with a total peak performance above xx TeraFLOPS. Please see the Hardware page for further details.

In 2009 a new computer room for Niflheim was constructed at DTU for housing the expansion of the system. A unique computer room design was implemented together with the consulting company Alectia such that the room consists of completely separated cold aisles and hot aisles, thereby eliminating inefficiencies due to the mixing of cold and hot air. Together with the centralized DTU cooling service providing chilled water, this is a highly optimized cooling technology. Also, the new series of Intel Xeon 5500 series CPUs are significantly more energy efficient than previous CPU technologies, leading to an overall extremely energy efficient computer installation.

Please consult the Getting_Started page for information about how to use the Niflheim system.

For Niflheim usage statistics please see the DCSC usage graphs. You may also read about the Niflheim_name.
