Title: Computer system with interference protection
IPC: G06F9/46
Filed: 1977-05-05
Abstract: 1525208 Interference protection HONEYWELL INFORMATION SYSTEMS Inc 5 May 1977 [7 May 19761 18835/77 Addition to 1518829 Heading G4A In a computing system as described in Specification 1,518,829 including a protection system for preventing interferences between processes which maintains a continuously updated record of the history of utilization of resources by processes, processes can be in the wait states and the possible relationships between processes are "follows but does not depend upon" (1) (write follows read) and "follows and waits" (3) (e.g. write follows write). The continuously updated record of the history of utilization of the resources may be maintained by a set of utilization tables, Fig. 9a, one for each resource and indicating the processes which have previously accessed that resource and whether each access was a read (r) or write (w), a matrix, Fig. 9b, of the relationships between processes resulting from the sequential accessing of the resources by the processes, and affected resources lists, Fig. 9c, one for each process. This allows at most one version of each resource to be in a non-cleared status and reduces the number of processes to be aborted if an interference is detected. If the requesting process has already written the resource or repeats a previous reading, as indicated by the utilization tables, the request is allowed; otherwise it is determined what new relationships the requested access implies. If a new relationship (or the same relationship of the other type, 1 or 3) already exists in the matrix, the access is allowed whereas if its inverse exists explicitly or implicitly in the matrix the access is denied; if neither exists the access is allowed, the utilization tables, the matrix, and the affected resources lists being updated. If a read access is denied because it cannot be routed to a cleared version of the resource it enters a wait status. If a write access is derived the write access or the process it follows may be aborted. Alternatively all processes may be rolled-back to a previous check point.
