We consider the sharing of processors in parallel computer systems. In general, the main goal of the systems, better performance, decreases processor utilization. We model and simulate a multi-tasking parallel operating system, and estimate its performance degradation and overall system throughout in the case where threads share a processor. We formalize the system by using DEVS (Discrete Event System Specification), and implement it in the DEVS simulation environment. Simulation results show that the processor sharing between threads is acceptable in the sense of TPP (throughput per processor)
