Niflheim Linux supercomputer cluster
The Niflheim Linux cluster supercomputer is installed at the Department of Physics at the Technical University of Denmark. Niflheim's present compute resources consist of 24560 CPU cores with a total peak performance of more than 1785 TeraFLOPS (1785 million million floating-point operations per second). Please see the Hardware page for further details.
Niflheim is available to all HPC users (staff as well as students) at DTU.
DTU departments who have not used Niflheim previously should first contact Prof. Karsten W. Jacobsen (email@example.com) so that new user groups and disk space can be allocated.
Existing user groups on Niflheim should send requests for new users to the Niflheim_support E-mail.
Please consult the Niflheim7_Getting_started page for information about how to use the Niflheim system.
For Niflheim usage statistics please see the monthly Niflheim accounting reports.
The NIFLHEIM cluster supercomputer was given a name through a naming competition held at the CAMP research 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.
The NIFLHEIM cluster supercomputer was originally 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.
