Abstract:
1. A method for emulating operating system jitter on a platform using a given trace, comprising the steps of: calculating a scale factor, wherein the scale factor is equal to a maximum of measured overhead of introducing synthetic jitter on the platform and a resolution of one or more timer calls on the platform; scaling up each of one or more jitter values and each of one or more gaps between each of one or more jitter instances in the trace and an execution period of a benchmark parallel application using the scale factor; introducing synthetic jitter using each of the one or more scaled jitter values and each of the one or more scaled gaps from the trace while running the benchmark parallel application for the scaled execution period to emulate operating system jitter on a platform; and scaling down one or more final time measurements from the benchmark parallel application by the scale factor.
