多处理器的使用可以从两方面提高系统性能.首先,它减少了在执行多个任务时模拟并发的需要. 其次,他可以使应用程序运行得更快,当然,这必须要求程序是以多线程方式来书写的,这些线程可以并行地高效执行.

Use multiple processors can improve system performance at two ways. First, it reduced the need of perform multiple tasks simulate concurrency. Second, it can let program run faster, sure, it required program use multip threads write, that can efficient execute parallel.

指令集并行:现代处理器可以同时执行多条指令.

instruction-Level Parallelism:modern processors can execute multiple instructions at on time.
