The role of the kernel of the operating system EMAS 2900 and the implementation of its functions are described in some detail. The significance of local scheduling policies and their implications on the design of the kernel are discussed with particular reference to paging management and scheduling control. It is shown that the concept of local and global control of resources can lead to a considerable simplification in the structure of an operating system kernel. The resulting operating system, EMAS 2900, provides interactive time‐sharing services very effectively and efficiently to a large computing community.
