开放式IoT自动GPU卸载技术研究

Study of Automatic GPU Offloading Technology for Open IoT

Yoji Yamato, Tatsuya Demizu, Hirofumi Noguchi, Misao Kataoka

摘要:

物联网技术已经取得了进展。开放式物联网(Open IoT)的概念通过整合水平分离的设备和服务来实现各种物联网服务。对于开放物联网时代,我们提出了隐性计算技术,以发现用户需要的数据设备,并动态使用它们。然而,现有的默会计算并不关心性能和操作成本。因此,本文提出了一种GPU自动卸载技术,作为默会计算的基础技术,该技术利用遗传算法提取合适的卸载循环语句来提高性能。我们评估了一个C/C++矩阵操作,以验证GPU卸载的有效性,并确认在1小时的调整时间内性能提高了35倍以上。

英文摘要:

IoT technologies have been progressed. Now Open IoT concept has attracted attentions which achieve various IoT services by integrating horizontal separated devices and services. For Open IoT era, we have proposed the Tacit Computing technology to discover the devices with necessary data for users on demand and use them dynamically. However, existing Tacit Computing does not care about performance and operation cost. Therefore in this paper, we propose an automatic GPU offloading technology as an elementary technology of Tacit Computing which uses Genetic Algorithm to extract appropriate offload loop statements to improve performances. We evaluate a C/C++ matrix manipulation to verify effectiveness of GPU offloading and confirm more than 35 times performances within 1 hour tuning time.
