As computer time-sharing systems have evolved from a research activity to an operational activity, and have increased in size and complexity, it has become clear that significant problems occur in controlling the use of such systems. These problems have evidenced themselves in computer scheduling, program capability constraints, and the allotment of auxiliary storage. The general-purpose systems of today have all experienced these problems. However, the severity of the overload condition varies greatly with each system. This is due to the kinds of user programs that are being processed, the hardware available for servicing them, the operational role of the system, and the amount of built-in software constraints on the areas of potential overload. The SDC Time-Sharing System (TSS) has a minimal number of built-in user restrictions and has developed the Manager program to control its overload problems.
