        {SP/2}
     
        [Which is correct?]

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}.
