    <description>The IBM 1800 data acquisition and control computer
    was introduced in Dec'1964 and intended for industrial process control
    applications. It could be linked to the IBM System 360 (which had been
    announced six months earlier) to increase its own computing power or
    to form a management information system in which production line data
    was used to update inventory records, perform accounting or handle
    other general data processing jobs.  </description>

    <description>The S/370 data processor was a main frame computer
    introduced in June 1970 as a successor to the S/360.  The S/370 had 2x
    CPUs and memory based on integrated circuits rather than magnetic
    cores.  </description>

    at Borehamwood and Dunstable. Users of GEC 4000 series systems
    included many British university physics and engineering departments,
    the central computing service of University College London (Euclid)
    and Keele University, the JANET academic and research network X.25
    switching backbone, Rutherford-Appleton Laboratory, Daresbury
    Laboratory, Harwell Laboratory, NERC, Met Office, CERN, ICI, British
    Telecom, and many others. At the Rutherford-Appleton Laboratory a GEC
    4000 system was used to control the synchrotron and injectors used for
    the ISIS neutron spallation source until 1998. See </description>

    the network and terminal concentrators and a number of other tasks. It
    has a 16-bit instruction set and data registers and approximately
    16 kB of Sension semi-conductor memory. The ``quick summary'' card and
    Digital books show how this computer would be

    <description>Floating Point Systems was a computer company from
    Beaverton, Oregon founded in 1970. The FPS-164 was introduced in
    1981. The FPS was used as an attached processor for scientific
    applications. At Daresbury, the front-end computer was the
    NAS/7000. The machine provided 64-bit vector processing capability
    similar to the Cray-1 and could be extended with additional MAX
    boards. This one initially had 3x 135 MB disks, one 600 MB disk and
    512 Kwords of main memory. The processor ran at 5.5 M instructions
    per second which could realise 11 Mflop/s plus up to 66 Mflop/s on
    three MAX boards.

    <description>Another era with Intel (USA) iPSC and i860 parallel
    computers. The British market with its transputers could not sustain
    the performance of the American and Japanese rivals using less
    specialised RISC processors. Commodity processers were engineered for
    the mass market so could be designed and produced quickly.
    32 sx/vx Intel nodes were provided by the SERC Science
    Board in 1988 for this second-generation Intel hypercube.  Each node
    had a 80386 plus Weitek 1167 floating point processor set and AMD vx
    vector co-processors and a total of 5 MByte of memory split between two
    processor boards (4 MByte scalar and 1 MByte vector memory). A further
    32 sx nodes and concurrent i/o system with 1.5 GBytes of disc were
    funded by ICI plc. reduced again to 32 nodes to fund ICI's stake in
    the iPSC/860. The system became obsolete and too expensive to maintain
    in 1993, it was however still being used in 1994 for system code
    development.  </description>

    <description>The Cray XT4 node board with 4x dual-core processor
    sockets was used on HECToR Phase-1 at EPCC. The processor was an AMD
    2.8 GHz Opteron. Each dual-core socket shares 6 GB of memory.  The
    theoretical peak performance of with 1,416 of these boards was 59
    Tflop/s. On Phase-2A they were replaced with quad-core Opterons with
    2.3 GHz clock speed and 8 GB memory per socket. The system was then
    capable of up to 208 Tflop/s.  </description>

    <description>Cray XE6 processor board from HECToR Phase-2B at EPCC.
    This has 8x AMD Opteron processors configured as 4x dual
    processor nodes with a proprietary inter-connect.
    Each node has two 12-core
    AMD Opteron 2.1 GHz Magny Cours processors.
    Each 12-core socket is coupled with a
    Cray Gemini routing and communications chip. Each 12-core
    processor shares 16 GB of memory. The theoretical peak
    performance of the HECToR Phase-2B system with 464 of these boards was
    over 360 Tflop/s.
