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 (2011), we own 224 CPUs on the UiO Titan cluster.

Geofag HPC staff

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

This is a cookbook for compiling WRF (the Weather Researching and Forecasting model). The WRF model underlies some of our research done on the Abel High Performance Computing (HPC) cluster.

 

This is the model results for temperatures in an area of Jotunheimen, from the surface down to 100m below ground. The model is our own cryoGRID_1.0, run on a Matlab installation. Image courtecy of Thomas Schuler.

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 Titan cluster. It is somewhat expensive, and there is of course never enough resources for everyone to run as big models as they would like.

This is an example of a Matlab submit script for use on the Abel cluster. Abel usage is documented at UiOs HPC pages
