Betzy¶
Named after Mary Ann Elizabeth (Betzy) Stephansen, the first Norwegian women to be awarded a doctorate degree.
The most powerful supercomputer in Norway¶
Betzy is a BullSequana XH2000, provided by Atos, and will give Norwegian researchers more than 5 times more capacity than previously, with a theoretical peak performance of 6.2 PetaFlops. The supercomputer, which will be placed at NTNU in Trondheim, will be available to users during the second half of 2020.

No network access on compute nodes¶
According to our security policy, compute nodes shall not have direct access to
the public internet. This means that commands like git clone or conda install or pip install, updating Git submodules, fetching data from web
sources, etc., will not work on compute nodes.
