The CRAY Series,lude instructions which implicitly process a sequence of vector elements. Computers with this latter facility have been described by Flynn [Fly72] as Single Instruction Multiple Data (SIMD) arrangements, in contrast with the Single Instruction Single Data (SISD) arrangement of conventional computers

The CDC Series,ch is now produced commercially as the CYBER 205. In 1983 CDC formed a spin-off company, ETA Systems Inc., with the goal of producing a multiprocessor system (the ETA.), based on the CYBER 205 architecture and having a performance capability of 10 GigaFLOPS.

Performance of Vector Machines, is analysed it is useful to separate the architectural measurements from the technological measurements since this permits a comparison of the . of machines constructed from different technologies. This chapter therefore considers the ways in which the performance potential of vector processors can

Initially users were required to organise their own store transfers between a selected drum track and a selected pair of Williams Tubes, but the Mark 1 A

This problem also impinges on instruction accessing, since for efficient operation instructions must also be supplied to the processor at a rate matching its execution rate. In the case of instruction accessing, however, the problem is ameliorated by the fact that most instru
