Concurrency Computation Practice and Experience | Year: 2014

With the emergence of general-purpose computation on graphics processing units, high-level approaches that hide the conceptual complexity of the low-level Compute Unified Device Architecture and Open Computing Language platforms are the subject of active research. However, these approaches may require a trade-off in terms of achieved performance and utilisation on graphics processing units hardware and may impose algorithmic limitations. In this paper, we present and systematically evaluate the parallel performance of three implementations of the brute force, all-pairs N-body algorithm with skeletal deployments based on the FastFlow, SkePU and Thrust frameworks. Our results indicate that the skeletal framework implementation achieves up to two orders of magnitude speed-up over serial version with a Tesla M2050 with lower implementation complexity than low-level Compute Unified Device Architecture programming.

A revolution is happening in computer hardware. After three decades during which microprocessor speeds increased almost 4000 times, we are starting to hit long-predicted physical limits on the speed of a single processor. Recent computers instead use two, four or even twelve processor cores working together ``in parallel, giving peak performance that is equivalent to a 5GHz, 10GHz or even 30GHz single processor, but at a fraction of the projected energy usage. There have even been experimental 48-core ``single cloud computer chips giving peak performance that would exceed that of a 100GHz single processor. The effective exploitation of such high performance is essential to support modern demands for computing power in the home, in industry and in the economy at large. Combining this with low energy usage is crucial if the performance is to be delivered at a reasonable financial and environmental cost.Future designs will harness even greater numbers of processor cores, perhaps in the thousands or millions, and perhaps with widely varying speeds and capabilities. These will be combined with advanced graphics processor units and other specialist units to give further performance and energy gains. In this way we will be able to meet societys future needs for computing power.While there are already significant challenges in building computers, such as those described above, from heterogeneous processor and other computing units, there are even greater challenges in building parallel software that can use them effectively. In order to do this, we must produce software that is easy to write but that still allows the hardware to be used effectively.The key innovation of the ParaPhrase project is exactly to produce such software that is easy to write using the hardware more effectively with the goal of speeding up processing by at least one order of magnitude over sequential execution on real near-term multicore architectures for the use cases and systems that will be considered in the project.ParaPhrase will build on a (multi-level) model of parallelism, where implementations of parallel programs are expressed in terms of interacting components. By expressing parallelism in terms of high-level parallel patterns that have alternative parallel implementations, we will be able to redeploy/refactor parallel components to dynamically match the available hardware resources.One large scale company (MELLANOX), one SME (ERLANG SOLUTIONS) and an Austrian software competence centre (SCCH) with strong links to industry will exploit the project results in a commercial context. ParaPhrase will strengthen their respective market position and competitiveness and give a manifold return on investment. The six academic partners will use the gained knowledge to enrich their teaching activities and to reinforce their prestige in the scientific community. European citizens will benefit from less power-consuming computers.

Teens' risky driving drops considerably in the two months following a serious collision, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research, involving data on actual driving behavior from over 250 teens, suggests that involvement in a severe crash may prompt adolescents to engage in safer driving behavior. "Crashes are not a good thing and every driver should try their best to avoid having one. But our research did uncover a positive aspect to an otherwise negative occurrence," says lead researcher Fearghal O'Brien of the National College of Ireland, who conducted the analysis as a postdoctoral fellow at the U.S. National Institutes of Health. "Our data showed that elevated acceleration events - including rapid turns, stops, and other aggressive maneuvering - were higher among those who later crashed compared to those who did not. But these rates declined for at least two months following a crash, indicating safer driving behavior." These data are particularly notable, says O'Brien, because of the way they were collected: "The technologies used meant we did not have to rely on self-report measures of driving behavior. Additionally, this study measured the same participants before and after a crash, unlike most research studies which only have access to participants after the negative event occurs." Previous research had indicated the drivers' risk of crashing is high when they start driving but drops noticeably over the first few years. While age and experience are likely to play a role in this change, O'Brien and colleagues wondered whether involvement with a crash might also influence driving behavior over time. For the study, the researchers examined data from 254 16- and 17-year-olds who were participating in the Naturalistic Driving Study as part of the Strategic Highway Initiative Program 2. The teenagers' cars were outfitted with a device that measured acceleration and cameras that recorded their driving from various angles. O'Brien and colleagues decided to focus specifically on the teens' involvement in police-reportable and severe collisions, which included any accident resulting in significant damage, airbag deployment, injury, or a rollover. The data revealed that the rate of high-acceleration events - a sign of risky driving - dropped by about 34% immediately after a teen was involved in a severe collision. After about two months, the rate of such risky events tended to increase again, but continued to stay below pre-collision levels. "An encouraging finding is that this change in driving behavior can happen over a very short time - in just a few days, drivers became much safer," O'Brien explains. "The finding suggests that young drivers learn from the feedback from a crash." The study advances our understanding of the relationship between real driving experiences and actual driving behavior, but this field of research is still in its early stages. "We need to replicate and expand these findings with other datasets," O'Brien says. "With more participants, and improved measures, we can examine how long these changes last, and, we hope, develop safer ways to get them to correct their risky driving behaviors." The researchers plan to extend this line of research to explore whether the same decrease in risky driving occurs after less severe crashes and whether changes in driving are proportionate to the severity of a crash. Co-authors on the study include Joe Bible, Danping Liu, and Bruce G. Simons-Morton, all of the Eunice Kennedy Shriver National Institute of Child Health and Human Development at the National Institutes of Health. The research was supported by the intramural research program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (Contract HSN275200800002I/HHSN27500010).

User Modeling and User-Adapted Interaction | Year: 2010

The evaluation of interactive adaptive systems has long been acknowledged to be a complicated and demanding endeavour. Some promising approaches in the recent past have attempted tackling the problem of evaluating adaptivity by "decomposing" and evaluating it in a "piece-wise" manner. Separating the evaluation of different aspects can help to identify problems in the adaptation process. This paper presents a framework that can be used to guide the "layered" evaluation of adaptive systems, and a set of formative methods that have been tailored or specially developed for the evaluation of adaptivity. The proposed framework unifies previous approaches in the literature and has already been used, in various guises, in recent research work. The presented methods are related to the layers in the framework and the stages in the development lifecycle of interactive systems. The paper also discusses practical issues surrounding the employment of the above, and provides a brief overview of complementary and alternative approaches in the literature. © 2010 Springer Science+Business Media B.V.

Mobile Internet and mobile services that make use of mobile data are increasingly popular. However, the cost of content delivery, in particular, multimedia type content over cellular networks is still high and poses a challenge for some users who are not necessarily willing or cannot afford to pay too much for it. The problem is further exacerbated when video content is used, as this type of content is heavier and can lead to higher bills. In this context, this paper presents a novel cost-oriented adaptive multimedia delivery (COMEDY) mechanism that considers the user's willingness to pay for a certain video quality and user's mobile device characteristics to deliver adaptive multimedia content over wireless connection. The goal of the mechanism is to reduce the cost of multimedia delivery for users that are not willing to pay that much. The mechanism is evaluated both through objective and subjective studies. The evaluation shows that the proposed mechanism provides a reduction in the price paid for accessing multimedia content, and the user's perceived quality is not negatively affected. © 1963-12012 IEEE.

Background: Most measures of the cancer burden take a public health perspective. Cancer also has a significant economic impact on society. To assess this economic burden, we estimated years of potential productive life lost (YPPLL) and costs of lost productivity due to premature cancer-related mortality in Ireland.Methods: All cancers combined and the 10 sites accounting for most deaths in men and in women were considered. To compute YPPLL, deaths in 5-year age-bands between 15 and 64 years were multiplied by average working-life expectancy. Valuation of costs, using the human capital approach, involved multiplying YPPLL by age-and-gender specific gross wages, and adjusting for unemployment and workforce participation. Sensitivity analyses were conducted around retirement age and wage growth, labour force participation, employment and discount rates, and to explore the impact of including household production and caring costs. Costs were expressed in €2009.Results: Total YPPLL was lower in men than women (men = 10,873; women = 12,119). Premature cancer-related mortality costs were higher in men (men: total cost = €332 million, cost/death = €290,172, cost/YPPLL = €30,558; women: total cost = €177 million, cost/death = €159,959, cost/YPPLL = €14,628). Lung cancer had the highest premature mortality cost (€84.0 million; 16.5% of total costs), followed by cancers of the colorectum (€49.6 million; 9.7%), breast (€49.4 million; 9.7%) and brain & CNS (€42.4 million: 8.3%). The total economic cost of premature cancer-related mortality in Ireland amounted to €509.5 million or 0.3% of gross domestic product. An increase of one year in the retirement age increased the total all-cancer premature mortality cost by 9.9% for men and 5.9% for women. The inclusion of household production and caring costs increased the total cost to €945.7 million.Conclusion: Lost productivity costs due to cancer-related premature mortality are significant. The higher premature mortality cost in males than females reflects higher wages and rates of workforce participation. Productivity costs provide an alternative perspective on the cancer burden on society and may inform cancer control policy decisions. © 2014 Hanly and Sharp; licensee BioMed Central Ltd.

As mobile devices are becoming more compact and powerful and as they start to be increasingly used for accessing power-hungry multimedia streaming applications, there is an increasing need for mechanisms to efficiently manage the limited battery power resources. This is especially important as the battery capacity has not kept up with the power requirements of an increasing number of mobile device features and always on connected users. Adaptive multimedia-based power-saving mechanisms often decrease the clip bitrate to increase the mobile device battery life, without considering the effect of these degradations on the user-perceived quality. This paper proposes BitDetect, a mechanism that uses objective video quality assessment metrics to detect content-specific video bitrate levels that enable saving battery power while maintaining good user perceived quality. Results from a subjective study indicate that the recommended bitrate offers good user-perceived quality across different multimedia clips. Furthermore, experimental tests indicate that significant battery power can be saved by using the recommended bitrates when streaming multimedia clips to a mobile device. © 2012 IEEE.

As mobile devices are becoming more powerful and affordable they are increasingly used for mobile learning activities. By enabling learners' access to educational content anywhere and anytime, mobile learning has both the potential to provide online learners with new opportunities, and to reach less privileged categories of learners that lack access to traditional e-learning services. Among the many challenges with mobile learning, the battery-powered nature of mobile devices and in particular their limited battery life, stands out as one issue that can significantly limit learners' access to educational content while on the move. Adaptation and personalisation solutions have widely been considered for overcoming the differences between learners and between the characteristics of their mobile devices. However, while various energy saving solutions have been proposed in order to provide mobile users with extended device usage time, the areas of adaptive mobile learning and energy conservation in wireless communications failed to meet under the same umbrella. This paper bridges the two areas by presenting an overview of adaptive mobile learning systems as well as how these can be extended to make them energy-aware. Furthermore, the paper surveys various approaches for energy measurement, modelling and adaptation, three major aspects that have to be considered in order to deploy energy-aware mobile learning systems. Discussions on the applicability and limitations of these approaches for mobile learning are also provided. © 2014 IEEE.

The recent judgment of the International Court of Justice in the Pulp Mills (Argentina v Uruguay) case makes a very important and timely contribution to the ongoing development of international law relating to shared international water resources and to international environmental law more generally. It does much to clarify the relative significance of the procedural obligations imposed upon co-riparian States and the nature of the relationship between procedural and substantive rules of international water law and international environmental law. In particular, the Court has stressed the importance of inter-State notification of new projects or activities, linking notification to discharge of the customary due diligence obligation to prevent significant transboundary harm. In turn, it has found that a process of environmental impact assessment (EIA) is absolutely central to such notification and, therefore, that EIA is an essential requirement of customary international law in respect of projects or activities potentially having transboundary effects. Unfortunately, the Court was not prepared to identify the minimum core components of an adequate EIA. In addition, the Court has confirmed that, in the specific context of shared international water resources, the principle of equitable and reasonable utilisation, universally accepted as the cardinal rule of international water law, is virtually synonymous with the concept of sustainable development. This finding confirms that the former principle 'operationalises' sustainable development in respect of international water law and further suggests that considerations of environmental protection are absolutely integral to the equitable balancing of interests involved therein. Generally, the judgment makes it clear that the principle of equitable utilisation ought to be understood as a process, rather than as a normatively determinative rule. © The Author [2010].
