  • Online Power Management for Multi-Cores: a Reinforcement Learning Based Approach
    1 Online Power Management for Multi-cores: A Reinforcement Learning Based Approach Yiming Wang, Weizhe Zhang, Senior Member, IEEE, Meng Hao, Zheng Wang, Member, IEEE Abstract—Power and energy is the first-class design constraint for multi-core processors and is a limiting factor for future-generation supercomputers. While modern processor design provides a wide range of mechanisms for power and energy optimization, it remains unclear how software can make the best use of them. This paper presents a novel approach for runtime power optimization on modern multi-core systems. Our policy combines power capping and uncore frequency scaling to match the hardware power profile to the dynamically changing program behavior at runtime. We achieve this by employing reinforcement learning (RL) to automatically explore the energy-performance optimization space from training programs, learning the subtle relationships between the hardware power profile, the program characteristics, power consumption and program running times. Our RL framework then uses the learned knowledge to adapt the chip’s power budget and uncore frequency to match the changing program phases for any new, previously unseen program. We evaluate our approach on two computing clusters by applying our techniques to 11 parallel programs that were not seen by our RL framework at the training stage. Experimental results show that our approach can reduce the system-level energy consumption by 12%, on average, with less than 3% of slowdown on the application performance. By lowering the uncore frequency to leave more energy budget to allow the processor cores to run at a higher frequency, our approach can reduce the energy consumption by up to 17% while improving the application performance by 5% for specific workloads.

    WWRF VIP WG CONNECTED VEHICLES White Paper Connected Vehicles: The Role of Emerging Standards, Security and Privacy, and Machine Learning Editor: SESHADRI MOHAN, CHAIR CONNECTED VEHICLES WORKING GROUP PROFESSOR, SYSTEMS ENGINEERING DEPARTMENT UA LITTLE ROCK, AR 72204, USA Project website address: www.wwrf.ch This publication is partly based on work performed in the framework of the WWRF. It represents the views of the authors(s) and not necessarily those of the WWRF. EXECUTIVE SUMMARY The Internet of Vehicles (IoV) is an emerging technology that provides secure vehicle-to-vehicle (V2V) communication and safety for drivers and their passengers. It stands at the confluence of many evolving disciplines, including: evolving wireless technologies, V2X standards, the Internet of Things (IoT) consisting of a multitude of sensors that are housed in a vehicle, on the roadside, and in the devices worn by pedestrians, the radio technology along with the protocols that can establish an ad-hoc vehicular network, the cloud technology, the field of Big Data, and machine intelligence tools. WWRF is presenting this white paper inspired by the developments that have taken place in recent years in standards organizations such as IEEE and 3GPP and industry consortia efforts as well as current research in academia. This white paper provides insights into the state-of-the-art regarding 3GPP C-V2X as well as security and privacy of ETSI ITS, IEEE DSRC WAVE, 3GPP C-V2X. The White Paper further discusses spectrum allocation worldwide for ITS applications and connected vehicles. A section is devoted to a discussion on providing connected vehicles communication over a heterogonous set of wireless access technologies as it is imperative that the connectivity of vehicles be maintained even when the vehicles are out of coverage and/or the need to maintain vehicular connectivity as a vehicle traverses multiple wireless access technology for access to V2X applications.

The need for tracking and evaluation of patients in real-time has contributed to an increase in knowing people’s actions to enhance care facilities. Deep learning is good at both a rapid pace in collecting frameworks of big data healthcare and good predictions for detection the lung cancer early. In this paper, we proposed a constructive deep neural network with Apache Spark to classify images and levels of lung cancer. We developed a binary classification model using threshold technique classifying nodules to benign or malignant. At the proposed framework, the neural network models training, defined using the Keras API, is performed using BigDL in a distributed Spark clusters. The proposed algorithm has metrics AUC-0.9810, a misclassifying rate from which it has been shown that our suggested classifiers perform better than other classifiers.
