摘要

科学并行应用需要更多的计算能力,要产生这样的计算能力,我们需要高端硬件。这种硬件消耗更多的电力并产生大量的热量。冷却系统需要确保硬件是健康的,否则它将容易出现故障。因此,数据中心的运营成本将会更高,而且对环境也不友好。通过降低功耗,我们可以降低成本,并使数据中心环保。这项工作提出了一种基于软件的动态电压和频率缩放技术,有助于降低并行应用的功耗。为了评估我们的技术,我们使用了流行的NAS并行基准测试,并观察到节能高达40%。

Software based DVFS technique for parallel applications to conserve the power
Scientific parallel applications need more computing power, to produce such computing power we need high end hardware. This hardware consumes more power and generates lot of heat. Cooling system is required to make sure that the hardware is healthy otherwise it will be prone to failure. As a result cost of data center operation will be more and it will not be environmental friendly. By reducing the power consumption we can reduce the cost as well as make data center environmental friendly. This work proposes a software based Dynamic Voltage and Frequency Scaling technique which helps in reducing the power consumption by parallel applications. To evaluate our technique we used popular NAS parallel benchmark and observed that up to 40% energy saving is achieved.
