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' sAIXoperating 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}.
