1. A method of estimating the scalability of a computer processor system including a processor, the processor having a core, the core capable of running a thread, the thread capable of supporting a task and the processor running an operating system;

  • the method comprising;

    estimating an operating system scalability factor;

    estimating a thread scalability factor;

    estimating a CPU scalability factor;

    estimating a processor scalability factor;

    iteratively combining the operating system scalability factor, thread scalability factor, CPU scalability factor and processor scalability factor in an equation having a linear element and a non-linear element to arrive at a result;

    computing the result to a measured parameter to arrive at an error;

    comparing the error to a predetermined maximum; and

    accepting the result as a scalability factor of the computer processor system.
