Reevaluating the overhead of data preparation for asymmetric multicore system on graphics processing


Abstract

As processor design has been transiting from homogeneous multicore processor to heterogeneous multicore processor, traditional Amdahl’s law cannot meet the new challenges for asymmetric multicore system. In order to further investigate the impact factors related to the Overhead of Data Preparation (ODP) for Asymmetric multicore systems, we evaluate an asymmetric multicore system built with CPU-GPU by measuring the overheads of memory transfer, computing kernel, cache missing and synchronization. This paper demonstrates that decreasing the overhead of data preparation is a promising approach to improve the whole performance of heterogeneous system.
