SP/2

   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.
