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}.
