      The adaptation of the DISPAK OS to the Elbrus-1 multiprocessor server is discussed. The reasons for creating a single OS for the BESM-6 and the server are examined. Adequate multiprocessor architecture mapping оп the operation system is analyzed.
      The DISPAK is the first opergtfon system implemented for a server. It provides the BESM-6 environment and the server compatibility, which permits the latter to use the software resources developed during the BESM-6 life time. However, the Elbrus-1 multiprocessor nature encourages one to further improve the operation system. Implementations, discussed here (multicomputer and multiprocessor) progressively bring us close to an operation system for multiprocessing. Multicomputer/multiprocessor combination allows to unify a multiprocessor efficiency and multicomputer reliability. The DISPAK OS utilization demonstrated it to be functionally complex and to have a high performance.
