MIMD systems can be classified into (150) -oriented systems, high-availability systems and response-oriented systems.
The goal of (150) -oriented multiprocessing is to obtain high (150) (151) minimal computing cost. The techniques employed by multiprocessor operating systems to achieve this goal take advantage of an inherent processing versus input/output balance in the workload to produce (152) and (153) . loading of system (154)
