Real-Time and Real-Fast Performance of General-Purpose and Real-Time Operating Systems in Multithreaded Physical Simulation of Complex Mechanical Systems

Figure 8

Missed deadlines in Linux when using a high number of threads with few masses and a short time step. The x-axis shows the number of elements to simulate and the y-axis the number of concurrent threads. Each black point represents a configuration for which at least one time step was not computed in real-time.
