Welcome to Anselm supercomputer cluster. The Anselm cluster consists of 209 compute nodes, totalling 3344 compute cores with 15 TB RAM, giving over 94 TFLOP/s theoretical peak performance. Each node is a powerful x86-64 computer, equipped with 16 cores, at least 64 GB of RAM, and a 500 GB hard disk drive. Nodes are interconnected through a fully non-blocking fat-tree InfiniBand network, and are equipped with Intel Sandy Bridge processors. A few nodes are also equipped with NVIDIA Kepler GPU or Intel Xeon Phi MIC accelerators. Read more in [Hardware Overview](anselm/hardware-overview/).
The cluster runs with an [operating system](software/operating-system/) which is compatible with the RedHat [Linux family.](http://upload.wikimedia.org/wikipedia/commons/1/1b/Linux_Distribution_Timeline.svg) We have installed a wide range of software packages targeted at different scientific domains. These packages are accessible via the [modules environment](environment-and-modules/).
