The experimental Synthesis operating system has an assembler incorpo- rated within the kernel. To optimize system-call performance, the kernel assembles routines within kernel space to minimize the path that the sys- tem call must take through the kernel. This approach is the antithesis of the layered approach, in which the path through the kernel is extended to make building the operating system easier. Discuss the and cons pros of the Synthesis approach to kernel design and to system-performance optimization.

Suppose that a multiprogrammed system has a load of N processes with individual execution times of t1, t2, ...,tN. Answer the following questions: a) How would it be possible that the time to complete the N processes could be as small as: maximum (t1, t2, ...,tN)? b) How would it be possible that the total execution time, T > t1+ t2+ ...+tN? In other words, what would cause the total execution time to exceed the sum of individual process execution times?
