The term multithreading is ambiguous, because not only can multiple threads be executed simultaneously on one CPU core, but also multiple tasks (with different page tables, different task state segments, different protection rings, different I/O permissions, etc.). Although running on the same core, they are completely separated from each other. Multithreading is similar in concept to preemptive multitasking but is implemented at the thread level of execution in modern superscal… WebThe symmetric multiprocessor (SMP) is the most popular form of multiprocessor system available, ranging from low-cost file servers with only two processors to high-performance graphics systems, such as Silicon Graphics's Power Challenge that contains up to 36 processors. In most SMP machines, all processors are connected in a shared backplane. …
