Operating C. Weissman; Systems Editor; Since the field of parallel processing in general, and multiprocessing in particular, is not current art, the design of HYDRA has a dual goal imposed upon it: (1) to provide, as any operating system must, an en-vironment for effective utilization of the hardware resources,

For example, the core scheduler and file-system components of most operating systems are relatively independent kernel services. Hence, two different spin locks can protect these two subsystems.

For the most part, multiprocessor operating systems are just regular operating systems. They handle system calls, do memory management, provide a file system, and manage I/O devices. Nevertheless, there are some areas in which they have unique features.

It then identifies some of the major design goals and key issues in multiprocessor operating systems. Is-sues and solution approaches are illustrated by review of a variety of research or commercial multiprocessor operating system kernels.
