Abstract : This paper addresses the question of CPU performance emulation, which allows experimenters to evaluate applications under a wide range of reproducible experimental conditions. Specifically, we propose Fracas, a CPU emulator that leverages the Linux Completely Fair Scheduler to achieve performance emulation of homogeneous or heterogeneous multi-core systems. Several benchmarks reproducing different types of workload (CPU-bound, IO-bound) are then used to thoroughly compare Fracas with another CPU emulator and hardware frequency scaling. We show that the design of Fracas results in a more accurate and a less intrusive CPU emulation solution.
