Visualisation systems

The HPAC Platform currently provides different visualisation systems at RWTH Aachen, Germany, and at EPFL in Geneva, Switzerland. If you would like to visit these sites for using the systems, please use our request form to let us know.


RWTH provides a fully immersive visualisation environment in the form of a CAVE installation. The aixCAVE is a five-sided virtual reality environment.

Tiled display walls

EPFL runs a thin-bezel, high-resolution display wall at Geneva. The wall consists of 4 x 3 55’’ displays, which form a 10 m2 display area with 7 mm bezels. Multi-touch input provides easy to use interaction with windows and content on the wall. It is driven by a single workstation using three NVIDIA GTX 980 GPUs, two Intel Xeon E5 CPUs (2 x 12 cores at 2.3 GHz) and 64 GB RAM.

Another tiled display wall is hosted at RWTH as a reference system of the system at EPFL. The display wall at RWTH consists of 6 full HD screens of 46’’ size. It is driven by a 7-node cluster (1 master and 6 slaves) each equipped with an Intel Xeon E5 CPU (4 cores at 3.7 GHz), 16 GB RAM, and 1 NVIDIA GTX 780Ti GPU each.
