The COKA Cluster is made up of one master node acting as a login front-end and 4 compute nodes named: node01, node02, node03, node04 In the compute nodes hyper-threading is disabled, although it is enabled in the login node.
The computing hardware of one node can be summarized by this schema:
Compute nodes are Supermicro SYS-4028GR-TR.
Each node embeds:
