Tony, reading through the News.Com article that John posted (which was very good reading) one "architecture/technology" comment I might make is the fact that the SP's "proprietary IBM interconnection hardware" involves, as you might expect from your experience, a lot of microcode (licensed machine code similar to your licensed internal code). It functions similar to the processor controller code on your bi-polar CECs as it controls partitioning MPs into A and B sides or logical partitioning via your MDF feature, or like switch code in a Parallel Sysplex. The Risc code distributes pieces of the job over the available Risc nodes. The more nodes, the faster it gets done. I believe there is some degradation but it is not to the same degree as you see with multi-engine degradation in a commercial mainframe environment.
