A distributed computer system having a plurality of digital computer systems interconnected by a bus. Each digital computer system runs one or more programs. When it receives a command directed to a system device or a program, it determines whether it can fulfill the command. If not, it determines which one of the other digital computer systems can fulfill the command based upon retaining information stored locally and forwards the command to the other digital computer system.

Distributed processing system having plural computers each using

A method of assigning priorities and resolving bus contention in a distributed computer system is disclosed. Each system node is assigned an identifier. Priorities are reassigned at each change in bus access such that the node that most recently had access to the bus is assigned the lowest priority with the node having the next identifier in sequence being assigned the highest priority and all other nodes assigned priority in accordance with their identifier's position in the sequence. The identifiers are logically treated as organized in a circular fashion such that the lowest node identifier is considered to come next in the sequence after the highest node identifier.
