IBM RS6000/SP2 is distributed memory system, or workstations linked with external high-speed switch. Sun's MP systems are all SMP design. SGI Power Challenge or Onyx are SMP too. The newer SGI Origin is SMP with special memory links -- ccNUMA. They are very different architectures while SP nodes are no different from IBM's RS6000 workstations. > peripherals. > > rgb > > Robert G.
