Compute Cluster
A cluster is a set of independent computers combined into a unified system through system
software and networking technologies. Compute clusters are important options for a
growing number of technical and commercial customers. The primary driver for clustering
of compute workstations and servers is that it provides a low cost alternative to
supercomputers. It also has the following key benefits:
horizontally scalable by adding more nodes
vertically scalable by using larger SMP nodes
fault-isolation - failure of a single Compute Node will not shutdown the
entire cluster system
asymmetry: mix and match of different nodes in a cluster
configuration flexibility: nodes, interconnect
re-deployable nodes
A compute cluster consists of Compute Nodes that incorporate multiple processors in a
symmetric multiprocessor configuration. These nodes are connected through interconnection
network(s) and are supervised within a single administrative domain. A compute cluster
usually resides in a single machine room and is managed as a single computer system. The
interconnection network employs standard local area network (LAN) and/or high
performance interconnect technologies based on the application requirements. A compute
cluster has to support both time-to-solution jobs and throughput jobs. HP high performance
technical computing cluster is available on HP Integrity servers with interconnection options
