The Cray SX-6 is in fact the NEC SX-6 as marketed by Cray in the USA. It is
the predecessor of the NEC SX-8 and very similar to that system but with
processors that have peak performance of 9 instead of 16 Gflop/s. Also the
maximal multi-frame configuration only supports 1024 instead of 4096
processors. For the description of the NEC SX-8, see section the section on
the NEC SX-8.
