The HPC cluster is used by scientists for heavy computing tasks. It consists of 255 multi-core nodes, all connected through a high-speed (20 Gb/s) network.
The HPC cluster is divided into 3 parts:
236 nodes with
- 12 Opteron 2.6 GHz cores
- 24 GB memory
16 nodes with
- 24 Opteron 2.6 GHz cores
- 128 GB memory
and 1 node with
- 64 cores
- 512 GB memory
All 200 nodes are connected by an Infiniband switch, and are connected to 110 TB of storage.
The machines can be used to submit a large number of jobs. It is also possible to make use of the fast network between the nodes to submit a large parallel job. These jobs can run much faster than when running on a single core. In order to make use of this option programs often need to be adapted, for example by adding adding MPI calls. The CIT can assist you in making your program parallel.
The CIT also offers a beginnerscourse for using the cluster. More information can be found on the course page.
More information can be found on the page with documentation.
