General/Visualisation Nodes

Introduction

There are two visualisation nodes on Viper, visu01.hpc.hull.ac.uk and visu02.hpc.hull.ac.uk each with dual NVidia GeForce GTX 980 Ti graphics cards.

There are two main ways of using the visualisation nodes, X2go or VNC. VNC will tend to provide better performance on a fast network (i.e. when connected directly to the university network) while X2go will provide better performance on lower bandwidth connections (i.e. connecting remotely via the VPN).
