High Performance Computing - HPC

HPC is an important part of the department's activity.

HPC nodes

The Department owns computing nodes for its own internal use (supporting Master's theses etc.), and for parts of our external projects. UiO has a spare pool of nodes which can be used. Projects with needs exceeding these usually use NOTUR quotes. At present (2014), we own about 500 cores on the UiO Abel cluster.

Geofag HPC staff

All IT group members will be able to assist you in obtaining an Abel account, and can also assist you with simpler problems. Anne Fouilloux (also a member of the IT group at Geofag) has HPC support as one of his main tasks along with programming and teaching courses.

WRF (the Weather Researching and Forecasting model) has been installed on Abel. If you do not need to update the source code, you should use the pre-compiled version. In case, you are unsure, please contact us. The WRF model underlies some of our research done on the Abel High Performance Computing (HPC) cluster.

Basic information is given here. For more, visit  UIO WIKI pages.

Matlab is a data-manipulation software package that allows data to be analyzed and visualized using existing functions and user-designed programs. It is an important tool for many of our scientists and students. It is also somewhat expensive.

We have our HPC resources on the UiO HPC cluster. It is somewhat expensive, and there is of course never enough resources for everyone to run as big models as they would like.
