Hydra has three high-performance visualisation nodes, the specification of which can be seen in Hydra HPC System Capabilities . These can be used in conjunction with software such as VTK and paraview to visualise data using hardware accelerated rendering, ideally for interactive visualisation tasks.
Other non-interactive rendering tasks can also be carried out on standard compute nodes.
If you have requirements outside this then contact the team (see Contacting Support )
Since there are few visualisation nodes they should ideally be reserved for interactive visualisation.
