Scalable POWERparallel 2.
A line of RISC -based processors from IBM using symmetric multi-processing . SP/2 replaced SP/1.
The SP2 is a classical MPP design, based on a Shared Nothing architecture. The SP2 is an example of the Distributed Memory Processor (DMP) parallel model, with individual nodes interconnected over a LAN , or a High-Performance Switch (HPS). SP2 systems can have from 2 to 512 nodes. Each node is a RISC system/6000 running IBM 's AIX operating system .
The SP2 supports applications in both technical and commercial environments. In terms of commercial applications, the SP2 is typically being used in support of, MIS / DSS including data mining , business applications e.g. SAP , Alternative Mainframe / Mainframe Offload , LAN Server Consolidation .
