1.2 High Performance Computing – HP Cluster Platform Architecture
What makes HP Cluster Platform different from standard systems is the assignment of node
types, high-speed networks, and the interoperability efficiency gained by using High Performance
Computing Software manufactured by HP and other HP partners. This section describes the
basics of the HP Cluster Platform hardware architecture.
•
Nodes:
The two types of nodes included in a typical Cluster Platform configuration are:
—
Control node
: Each cluster has one control node. If the optional InfiniBand interconnect
is selected, the control node is also connected. The control node can also be used for
preprocessing, postprocessing, and computational workload.
—
Compute nodes
: Compute nodes are normally used for application computation rather
than administrative workloads.
