CPU, as a central component of a computer system, has been required as a unit which can dynamically handle more and more threads, and thus single thread application can benefit from thread-splitting or thread-relaying, multi-thread application can benefit from physical level threads-oriented optimizations, together with dynamic power consumption/frequency adjustment, the computing power of a processing system then to be determined. By current computer architecture, it is considered that physical memory (mostly managed by hardware side) and virtual memory (mostly managed by operating software side on drives slower than physical memory) together as a memory system is a non-divisional part of forming a processing system. And thus minimizing the bottle-neck of memory system can be a cost-effective way to improve overall processing performance. SciMark Processors is a software pack in SciMark serials to quickly measure computing power of a processor system by executing its instructions single-thread and multi-thread. It will automatically show efficiency of threading. SciMark Processors for Mac OSX is a member of Scimark software. It could be a good tool to make a comparison of performance of processing system among different operating systems and to understand their differences.
