Abstract

In up-to-date distributed operating systems, used for a plurality of applications, the synchronization of the processors must be sufficiently accurate. A typical application consists in synchronizing the access operations to distributed data bases. The processors used for that purpose must be accurately synchronized to ensure that they function satisfactorily at high performance. If the synchronization falls short of the accuracy standards required for a particular process, wait and idle times are incurred. For synchronizing N processor nodes P0 ... Pi ... Pn, this article proposes a ring interconnecting all processors Pi in two circular directions. Such a ring topology has considerable advantages over other, star or bus, topologies. In the description, the terms absolute and relative synchronization are used.
