Abstract

To meet the needs for energy savings in Internet of Things (IoT) systems, solar energy has been increasingly exploited to serve as a green and renewable source to allow systems to better operate in an energy-efficient way. In this respect, accurate photovoltaics (PV) power output prediction is a prerequisite for any energy saving scheme employed in these systems. In this talk, I am going to discuss a unified training framework combined with the LightGBM algorithm to obtain a prediction model, which can provide short-term predictions of PV power output. Compared with the training in a single powerful machine, our proposed framework is more energy-efficient and fits into devices with limited computation and storage capabilities. The experimental results show that our proposed framework is superior to other benchmark machine learning algorithms.

Abstract

Cloud computing has been established as an effective computing paradigm in science and business and many applications have been moved from traditional computing infrastructures to the cloud. Consequently, issues related to cloud resource allocation, application scheduling, timeliness, energy efficiency and cost have been important research areas. Particularly important in cloud computing is to run real-time applications. Effective scheduling techniques should be utilized ensuring that the deadlines will be met.

In recent years, smart devices and sensors have been widely adopted in many domains of life, contributing to the expansion of the Internet of Things (IoT). IoT applications generate huge amounts of data and most of them are real-time applications with hard deadlines. As a result, fog computing has appeared as a computing model extending the cloud to the edge of the network, thus reducing the latency of IoT data transmission and avoiding network congestion. The computational capacity of fog resources is usually limited, therefore appropriate scheduling of real-time applications is required to fully exploit the capabilities of cloud and fog computing ensuring QoS to the end users.

Towards this direction, in this keynote we will describe techniques and solutions to address challenges in scheduling real-time applications in cloud and fog computing platforms and we will conclude with future research trends in the cloud and fog computing areas.

Abstract

The booming growth and rapid development in embedded systems, wireless communications, sensing techniques and emerging support for cloud computing and social networks have enabled researchers and practitioners to create a wide variety of Cyber-Physical-Social Systems (CPSS) that reason intelligently, act autonomously, and respond to the users’ needs in a context and situation-aware manner. The CPSS are the integration of computation, communication and control with the physical world, human knowledge and sociocultural elements. It is a novel emerging computing paradigm and has attracted wide concerns from both industry and academia in recent years.

Currently, CPSS are still in their infancy stage. Our first ongoing research is to study effective and efficient approaches for CPSS modeling and general system design automation methods, as well as methods analyzing and/or improving their power and energy, security, trust and reliability features.

Once the CPSS have been designed, they collect massive data (Volume) from the physical world by various physical perception devices (Variety) in structured/semi-structured/unstructured format and respond the users’ requirements immediately (Velocity) and provide the proactive services (Veracity) for them in physical space or social space. These collected big data are normally high dimensional, redundant and noisy, and many beyond the processing capacity of the computer systems. Our second ongoing research is focused on the Big Data-as-a-Service framework, which includes data representation, dimensionality reduction, incremental and distributed processing, security and privacy, deep learning, clustering, prediction and proactive services, aiming at representing and processing big data generated from CPSS, providing more valued smart services for human and refining the previously designed CPSS.

This talk will present our latest research on these two directions. Corresponding case studies in some applications such as smart traffics will be shown to demonstrate the feasibility and flexibility of the proposed system design methodology and analytic framework.

Abstract

The rapid advancements in Information and Communication Technologies (ICTs) have been greatly changing our society, with clear societal and economic benefits. Mobile technology, Cloud, Big Data, Internet of things, services and technologies that are becoming more and more pervasive and conveniently accessible, towards to the realization of a 'smart' society’. At the heart of this evolution is the ability to collect, analyze, process and share an ever-increasing amount of data, to extract knowledge for offering personalized and advanced services. A major concern, and potential obstacle, towards the full realization of such evolution is represented by security and privacy issues. As a matter of fact, the (actual or perceived) loss of control over data and potential compromise of their confidentiality can have a strong detrimental impact on the realization of an open framework for enabling collection, processing, and sharing of data, typically stored or processed by external cloud services. In this talk, I will illustrate some security and privacy issues arising in emerging scenarios, focusing in particular on the problem of managing data while guaranteeing confidentiality and integrity of data stored or processed by external providers.

Abstract

Cellular underlay vehicle-to-vehicle (V2V) communication will play an important role in next generation mobile communications, where security is a critical issue. Most previous works relied on encryption/authentication algorithms to ensure V2V communication security. This work is to implement PHY-layer security via resource allocation in V2V communications. We formulate a secrecy capacity optimization problem, which is solved via decomposing a joint optimization problem into two subproblems: optimal subcarriers and power allocation problems. The subcarriers allocation subproblem is a three-dimensional (3D) search problem. We develop an iterative algorithm, based on which we transform a non-convex power allocation problem to a convex form before solving it using an alternating maximization (AM) algorithm. Simulation results validate the performance of the proposed resource allocation based PHY-layer security scheme.

Abstract

Simulation, with its experimentation and experience aspects, already provides solutions in a multitude of diverse application areas.

Simulation is model based. From this fundamental aspect of simulation, emanated many other model-based disciplines. Progress continued and over 170 disciplines, methodologies, and approaches benefit of being simulation-based.

Several “Grand challenges in M&S studies” exist. Some of the early challenges are currently part of the state-of-the-art of M&S.

The presentation will focus on two complementary aspects of simulation:

1. What other aspects of simulation can be useful in solving problems of increasing complexity? Some examples:
   • Multi-simulation-based predictive displays.
   • Simulation systems engineering-based approach to get prepared for unexpected conditions.
   • Beyond validation and verification: Failure avoidance in simulated systems.
2. Based on the adage: “Work smarter rather than harder and sharpen your axe” how can we advance M&S? Some examples:
   • Development of high-level model specification languages and simulation program generator software.
   • Development of model-bases to provide readily usable models and experimental frames.

Abstract

AI algorithms require huge amount of computing power. However, the fundamental limits of current CMOS technology brings the end of Moore's Law and Dennard Scaling. So domain specific architectures (DSA) become the mainstream of AI processing systems. We present the full-stack optimization technologies used by Huawei ascend AI computing platform. By jointly optimizing micro-architecture of processing cores, hardware systems, networking, runtime, compiler, deep learning graph engine(GE), AI framework mindspore, AI application SDK MindX and deep learning models, our approach achieves very high performance while keeping great power efficiency and programmability. The Atlas 300 serious AI training system can reach as high as 320TFlops of training performance while consuming adequate amount of power. The Atlas 900 AI super computer can achieve best ResNet-50 training performance. We also open-sourced our AI framework, which is called mindspore, to help the AI research community to speed up their research work.
