In the next few years, exascale computing systems will become available to the scientific community. These systems will require new levels of parallelization, new models of memory and storage, and a variety of node architectures for processors and accelerators. In the decade that follows, we can expect more of these changes, as well as increasing levels of hardware specialization. These systems will provide simulation and analysis capabilities at unprecedented scales, and when combined with advanced physical models, mathematical and statistical methods, and computer science and abstractions, they will lead to scientific breakthroughs. Yet the full power of these systems will only be realized if there is sufficient high-level programming support that will abstract details of the machines and give programmers a natural interface for writing new scienceapplications.

This demonstration presents a data-driven situation-specific site selection system (called D4S for short) for users who are eager to create a business (hotel, hot-pot restaurant, etc.). Given a business and some related parameters, it selects sites that may gain profits for this business. Unlike existing works, D4S uses the meaning of prevalent co-location patterns discovered from spatial data sets to learn the "symbiotic" relationships in business, which can help to select reliable sites. Furthermore, ontologies are used in order to classify the whole spatial data according to the semantic of businesses, which makes the results more accurate. The demonstration shows the high reliability of the result sites selected by D4S.

Site selection is one of the most crucial and important decisions made by any business. Such a decision depends on various factors of sites, including socioeconomic, geography, ecology, as well as specific requirements of businesses. The existing approaches for site selection (commonly used by economists) are manual, subjective and not scalable. This paper presents a data-driven situation-specific site selection approach (called D3SA for short) for users who are eager to create a business (hotel, hot-pot restaurant, etc.). Given a business and some related parameters, it recommends suggested sites that can satisfy users' requirements. Unlike existing works, we consider using prevalent co-location patterns discovered from spatial data sets to select the sites. Meanwhile, a novel co-location generation algorithm is pro-posed to discover co-location patterns efficiently. Furthermore, ontologies are used in order to classify the whole spatial data according to the semantic of businesses to assist to find the "best" co-location pattern. The experimental results evaluated based on both a real POI (Points of Interests) dataset in Beijing and ex-tended synthetic data sets show the effectiveness and efficiency of D3SA.

ICN (Information-Centric Networking) originally innovated for efficient content distribution, is now discussed to be applied to edge computing in IoT (Internet of Things) environment. In this paper, we focus on more flexible network processing environment, in-network processing, which is realized with ICN architecture. In our assumed environment, multiple functions are executed on different routers widely distributed in a whole network and the end-to-end optimal route for any data processing should be selected to satisfy various IoT applications' requirement. Our proposal, an on-demand routing method efficiently chains data and multiple functions compared to an existing proactive routing method. Also, our method reactively caches routing information in the network and realize scalable routing for ICN-based in-network processing.

The data in scientific and engineering computations is usually gifted physical meaning in the presence of nonnegativity. For high performance and effectiveness, it is necessary and beneficial to consider the prior nonnegativity in processing the nonnegative information. In this paper, we propose a Projective Hard Thresholding Pursuit (PHTP) method for the nonnegative sparse signal recovery. It reconstructs sparse signal by combining the nonnegative projection with HTP. Theoretically, we prove that the proposed algorithm can find all nonnegative s-sparse signals provided the sensing matrix has suitable restricted isometry property. Moreover, We extend this result to its fast version. Besides, we verify PHTP's convergence with the measurement error being nonzero. Numerical experiments demonstrate that PHTP outperforms HTP and Nonnegative Least Squares(NNLS) for nonnegative sparse recovery and denoising.

Traffic engineering at network edges is challenging given the latency-sensitive nature of all applications that need to be supported. End-to-end delay estimation and forecasts were essential traffic engineering tools even before the mobile edge computing paradigm pushed the cloud closer to the end user. In this paper, we model the path selection problem for edge traffic engineering using a risk minimization technique inspired by portfolio theory in economics, and we use machine learning to estimate path selection risks. In particular, using real latency time series measurements, both existing and collected with and without the GENI testbed, we compare four short-horizon latency estimation techniques, commonly used by the finance community to estimate prices of volatile financial instruments. Our results suggest that a Bayesian Network approach may lead to good latency (peak) estimation performance, as long as there are dependencies among the time series path latency measurements.
