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 AIXoperating 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}.
