Computer system with tasking

摘要: An integrated data processing and communication service is provided by a system which comprises plurality of nodes interconnected via packet-switched transport network. Each node includes database processor at least one processor, with number terminals hosts being connected to the latter front-end processor. Processes existing each are two types--application layer processes perform "useful work" on behalf customers vendor service, control processes, manages, or provides some part of, itself. The processors virtual memory program region address space process both process-specific image shared image. former weakly linked it, set primitives, communications services including file/database management, application control, interprocess communications, station access message services. Such also available for use within "supervisor" enforcement privileges primitives; allocation; condition handling; event services; establishment management tasking system.
