Niflheim Linux supercomputer cluster

Niflheim overview

The Niflheim Linux cluster supercomputer is installed at the Department of Physics at the Technical University of Denmark.

The computer hardware is funded primarily with grants from the Danish Center for Scientific Computing (DCSC), and from the Catalysis for Sustainable Energy (CASE) initiative at the Technical University of Denmark.

Niflheim's present compute resources consist of 6952 CPU cores with a total peak performance of more than 72 TeraFLOPS (72 million million floating-point operations per second). Please see the Hardware page for further details.

Access to Niflheim

Niflheim is available to DTU research groups who have invested grants in the system. Current grant holders are:

  • Karsten W. Jacobsen, DTU Fysik, CAMD and CASE.
  • Tejs Vegge, DTU Energy Conversion.
  • Mads Brandbyge, DTU Nanotech.
  • Jens H. Walther, DTU Mechanical Engineering.

Usage of Niflheim

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.

The name Niflheim

The NIFLHEIM cluster supercomputer was given a name through a naming competition held at the CAMP center in the summer of 2002.

In Nordic mythology Niflheim is the land of fog and ice, and Niflheim is part of the myth of creation: When the heat from Muspelheim melted the first drops of water from the ice of Niflheim, these drops formed into the giant Ymer, the first living creature. When Ymer was later killed, his dead body was molded into the world as we know it.

Read more about the Edda prose containing the Nordic myth of creation, see Prose Edda (see the Gylfaginning from IV. Gangleri said, in other translations known as Frá Niflheimi ok Múspelli section).

The NIFLHEIM cluster supercomputer is actually housed in a basement room with chilled air cooling, and NIFLHEIM is thus bitterly cold. This room is officially known as the Fog Room (in Danish: Tågerummet) because it was originally built with the purpose of experiments in the mid-1960'ies by Prof. R. E. H. Rasmussen trying to precipitate fog using electrical fields.
