With respect to details of the processor deployed in Hunter, please refer to this Slides.

Pre- and post processing

Within HLRS simulation environment special nodes for pre- and post processing tasks are available. Such nodes could be requested via the batch systems using the queue "pre" or queue "smp". Available nodes are

    4 nodes 3 TB Memory, 2 Socket AMD EPYC 9354 32-Core Processor, exclusive usage model, available by queue "pre"
    1 node  6 TB Memory, 2 Socket AMD EPYC 9354 32-Core Processor, shared usage model,    available by queue "smp"

more specialized nodes e.g. graphics, vector, DataAnalytics, ... are available in the Vulcan cluster.
If you need such specialized nodes on vulcan cluster for pre- or postprocessing inside your project located on hunter resources, please ask your project manager for access to vulcan.
