CX1000 scale-up symmetric multiprocessing nodes

The CX1000-SM and CX1000-SC nodes can be used for cluster computing, but they are designed for scale-up Symmetric Multi-Processing (SMP). When used for cluster computing, the CX1000-SM node is intended to be the ''master (service)'' node, although it can instead be a ''compute'' node. Similarly, the CX1000-SC node, when used for cluster computing, is intended to be a compute node, but can instead act as the master (service) node. Either or both the CX1000-SC and/or CX1000-SM nodes can be deployed in a HPC cluster. The CX1000-SM and CX1000-SC nodes, when used for SMP, are connected by a cache-coherency interconnect which is a built-in subassembly of the CX1000-SM and CX1000-SC nodes, rather than a standalone device, and is called the ''Drawer Interconnect Switch'' in Cray literature. The Drawer Interconnect Switch uses the Intel QuickPath Interconnect technology.

CX1000 scale-out cluster computing nodes

The CX1000 scale-out cluster computing group of systems consists of the CX1000

, CX1000-C compute Node, CX1000-G GPU Node and CX1000-HN Management Node. Unlike the CX1000-SM and CX1000-SC nodes, these nodes cannot be used for scale-up SMP, as they were designed without a cache-coherency capability. The CX1000-C and CX1000-G nodes both have blade form factors, and the CX1000-HN node is a rackmount 2U Server. The CX1000-HN is intended to act as the head (service) node in an HPC cluster, with CX1000-C and/or CX1000-G compute nodes.
