== Hardware ==
=== Node/Processor ===


Compute nodes as well as login nodes are equipped with
  AMD EPYC 7742 64-Core Processor
detailed information will be provided later. Please check for additional infos [https://www.amd.com/de/products/cpu/amd-epyc-7742 AMD Rome 7742]
With respect to node and processor details cf. here.

=== Interconnect ===
| valign="top" style="padding: 0; border: 1px solid #aaaaaa; margin-bottom: 0;" |
Hawk deploys an Infiniband HDR based interconnect with a 9-dimensional enhanced hypercube topology. Please refer to [https://kb.hlrs.de/platforms/upload/Interconnect_topology.pdf here] with respect to the latter. Infiniband HDR has a bandwidth of 200 Gbit/s and a MPI latency of ~1.3us per link. The full bandwidth of 200 Gbit/s can be used if communicating between the 16 nodes connected to the same node of the hypercube (cf. [https://kb.hlrs.de/platforms/upload/Interconnect_topology.pdf here]). Within the hypercube, the higher the dimension, the less bandwidth is available.

Topology aware scheduling is used to exclude major performance fluctuations. This means that larger jobs can only be requested with defined node numbers (64, 128, 256, 512, 1024, 2048 and 4096) in regular operation. This restriction ensures optimal system utilization while simultaneously exploiting the network topology. Jobs with a node number of < 128 nodes are processed in a special partition. Jobs over 4096 nodes are processed at special times.

Home directories as well as workspaces are handled in the same way as on Hazel Hen, so please cf. [[CRAY_XC40_Disk_Storage | Storage Description ]] regarding details.
 
<br>
 
== 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 system (follow this link for more info).
Available nodes are
  table...
    4 nodes 2 TB Memory 2 Socket AMD ...x TB local storage  shared usage model
    1 Node  4 TB Memory 2 Socket AMD    x TB local storage  shared usage model
 
 
more specialized nodes e.g. graphics, vector, DataAnalytics, ... are available in the [[NEC_Cluster_Hardware_and_Architecture_(vulcan)|Vulcan cluster]]
