Cluster Day 2011

Following the tradition started a few years ago, the members of the Numerical Relativity Group and of the IT Department would like to invite you to the 2011 edition of the Cluster-Day@AEI. As in the past, the meeting is meant as a forum to exchange experiences mainly in the use but also in the management of High Performance Compute Clusters, as well as a way to report on new approaches and future strategies in the supercomputing world.

The highlight of the event will be the official inauguration of the new HPC-cluster Datura. We have invited the Brandenburg Minister of Science, Research and Culture, Prof. Dr.-Ing. Dr. Sabine Kunst to give an opening address.

The meeting is planned on Tuesday, 5th April, with a start at 9:15 am with a program that will run into the late afternoon (with a break for lunch). Location: Lecture Hall in the Central Building of the Max Planck Campus. Please register here.

The main theme of the event is: German High Performance Computing in the new Decade. The morning session will be reserved for the scientific projects with reports from the groups at the AEI. The afternoon session will be dedicated to presentations from external colleagues from the Berlin/Brandenburg area.
