Building families of object-based multiprocessor kernels

The authors have developed a portable family of object-based multiprocessor operating system kernels that address extensibility, customizability and efficiency for medium to large-grain parallelism, based on a single set of kernel-provided abstractions. The family is extensible in that new abstractions and functionalities can be added easily and efficiently. It is customizable in that existing kernel abstractions and functions can be modified easily. Efficiency within the family is obtained by reliance on the language level for enforcement of protection boundaries
