Or what you above call logic board. Note that there can be other kinds of logic boards in there (the (spider?) router boards) if you have more then one chasis. It helps to disambiguate. In general, the thing thatthe interconnect network connects are called nodes/PEs (processing elements). A node PE can have a number of processors. Local memory is a per PE memory. The SGI O2K arch is a real cool one. You can incrementally add to it to expand. > Jamie Bowden > > -- > > If we've got to fight over grep, sign me up.
