The PS-2000 (ПС-2000, Russian: перенастраиваемая структура, reconfigurable system) was a Soviet supercomputer built in the 1980s.In the middle of the 1970s, it appeared, in the USSR, that the computing power available to process geophysics data, real-time space probes data, mineral prospecting, weather forecast, etc.was far to be sufficient, and that a new class of supercomputers, hundreds of times more powerful than the existing installed systems, was needed.[1] The development of ПС-2000 began in 1978, as a joint project between the Institute of Control Problems (IPU) in Moscow and the Impul's Scientific Production Association in Severodonetsk, under the supervision of Il’ya Itenberg and Vladislav Rezanov of Impul's and Iveri Prangishvili of IPU.In the full configuration, with 8 UO, the supercomputer consists of 5 cabinets, organised in a double-Y shape.
