TITLE: "Performance, Energy and Thermal Aware Algorithms for Hybrid Multicore Processors"

Abstract: Multi-core processors are poised to dominate the landscape of next generation computing for both desktops and exascale machines. Allocating tasks to cores remains a key challenge on these processors that is increasingly compounding for several reasons. First, with an escalating number of cores, these processors are becoming progressively complex and heterogeneous in nature. Second, the aggressive scalability of these designs can lead to significant power and heat dissipation, making the adjustment of the voltage and frequency of cores as essential considerations in scheduling. Third, efficient and effective chip-level power and performance optimization requires management of the memory usage, multi-level caches in conjunction with utilizing the cores. In this talk, I will present my research on simultaneously optimizing the goals of energy minimization and performance maximization while taking into account constraints due to thermal constraints and/or targeting multiple architectural elements such as cores and caches. Experimental results on actual machines for a variety of data parallel and task parallel applications will be presented.

TITLE: "NOMA – A Paradigm Shift in Multiple Access for Next Generation Wireless Networks"

Abstract: Non-orthogonal multiple access (NOMA) is an essential enabling technology for the fifth generation (5G) wireless networks to meet the heterogeneous demands on low latency, high reliability, massive connectivity, improved fairness, and high throughput. The key idea behind NOMA is to serve multiple users in the same resource block, such as a time slot, subcarrier, or spreading code. The NOMA principle is a general framework, where several recently proposed 5G multiple access techniques can be viewed as special cases. Recent demonstrations by industry show that the use of NOMA can significantly improve the spectral efficiency of mobile networks. Because of its superior performance, NOMA has been also recently proposed for downlink transmission in 3rd generation partnership project long-term evolution (3GPP-LTE) systems, where the considered technique was termed multiuser superposition transmission (MUST). In addition, NOMA has been included into the next generation digital TV standard, e.g. ATSC (Advanced Television Systems Committee) 3.0, where it was termed Layered Division Multiplexing (LDM). This keynote talk is to provide an overview of the latest research results and innovations in NOMA technologies as well as their applications. Future research challenges regarding NOMA in 5G and beyond are also presented.

TITLE: "Big Data: Challenges and Algorithms"

Abstract: We live in an era of big data. Voluminous datasets are generated and have to be processed in every area of science and engineering. Efficient techniques are needed to process these data. In particular, we need tools to extract useful information from massive data sets. Society at large can benefit immensely from advances in this arena. For example, information extracted from biological data can result in gene identification, diagnosis for diseases, drug design, etc. Market-data information can be used for custom-designed catalogues for customers, supermarket shelving, and so on. Weather prediction and protecting the environment from pollution are possible with the analysis of atmospheric data.  In this talk we present some challenges existing in processing big data in various disciplines. We also provide an overview of some basic techniques. In particular, we will summarize various data processing and reduction techniques.

Dr. R Venkatesha Prasad, Delft University of Technology

TITLE: Murphy Loves Constructive Interferenc

Abstract: The power of the Constructive Interference (CI) phenomenon was exploited for the first time by Ferrari et al. through their Glossy paper in IPSN 2011. Instead of avoiding interference by neighboring nodes, the Glossy protocol deliberately orchestrates simultaneous transmissions to achieve fast and efficient network-wide flooding. That insight of "embracing interference" prompted many researchers to go back to the drawing board. However, from the previous studies, there appears to be an inconsistent and often contradicting picture about the working of CI. In this keynote I will sketch the main developments around Constructive Interference over the last 5 years.  Further, I will present not only the understanding of CI with theory and rigorous experimentation, but also question its actual existence.
