CHPC

Center for High Performance Computing

Hardware

Here you can find more detailed information on the available hardware. As of January 2017, the cluster consists of 46 compute nodes. 5 of them are as we call them GPU nodes. The naming scheme (hostname) of non-GPU compute nodes:
doppler<node-number>
and for GPU aided nodes
dopplergpu<node-number>
where <node-number> ranges from 01 to 42.

Specifications

In the following table, basic specifications are given. The memory and swap values are those shown by running free -g on the corresponding machine. The frequency column shows the rated base clock speed.
