The HPE Cray EX system includes two types of nodes:
- Compute Nodes, where high performance computing applications are run, and node names in the form of
nidXXXXXX - Non-Compute Nodes (NCNs), which carry out system functions and come in three versions:
- Master nodes, with names in the form of
ncn-mXXX - Worker nodes, with names in the form of
ncn-wXXX - Utility Storage nodes, with names in the form of
ncn-sXXX
- Master nodes, with names in the form of
The HPE Cray EX system includes the following nodes:
- Nine or more non-compute nodes (NCNs) that host system services:
ncn-m001,ncn-m002, andncn-m003are configured as Kubernetes master nodes.ncn-w001,ncn-w002, andncn-w003are configured as Kubernetes worker nodes. Every system contains three or more worker nodes.ncn-s001,ncn-s002, andncn-s003for storage. Every system contains three or more utility storage node.
- Four or more compute nodes, starting at
nid000001.
