Abstract : Single-ISA heterogeneous multicore systems are emerging as a promising direction to achieve a more suitable balance between performance and energy consumption. However, a proper utilization of these architectures is essential to reach the energy benefits. In this paper, we demonstrate the ineffectiveness of popular OpenMP scheduling policies executing Rodinia benchmark on the Exynos 5 Octa (5422) SoC, which integrates the ARM big.LITTLE architecture.
