Hábrók Documentation

This is the page with the user documentation of the Hábrók HPC cluster of the University of Groningen.

Hábrók is the best of hawks according to Grímnismál in the poetic Edda, which makes clear that is an improved replacement of the previous cluster called “Peregrine”.

Askr Yggdrasils,
hann er æztr viða,
en seiþ blaðnir skipa,
Óðin ása,
en ióa Sleipnir,
Bilröst brúa,
en Bragi skálda,
Hábrók hauka,
en hunda Garmr.
Yggdrasil’s ash is
of all trees most excellent,
and of all ships, Skidbladnir,
of the Æsir, Odin,
and of horses, Sleipnir,
Bifröst of bridges,
and of skalds, Bragi,
Habrok of hawks,
and of dogs, Garm.
Codex Regius English translation by Benjamin Thorpe
in “Edda Sæmundar Hinns Frôða” 1866

The cluster can be used by scientists from the university for performing simulations and data analyses. The scientific output generated by the use of the cluster and its predecessors has been gathered on Scientific output.
