Shen, J. (author)Heterogeneous platforms are mixes of different processing units in a compute node (e.g., CPUs+GPUs, CPU+MICs) or a chip package (e.g., APUs). This type of platforms keeps gaining popularity in various computer systems ranging from supercomputers to mobile devices. In this context, improving their efficiency and usability has become increasingly...doctoral thesis 2015

Zeilemaker, N.S.M. (author)P2P networks employ the resources available at peers to reduce the load at, or eliminate the need for a server. In order to achieve these goals, protocols are implemented which aim to allow peers to collaborate efficiently. However, these same protocols can make peers an easy target, as their willingness to collaborate can be susceptible to...doctoral thesis 2015

Burghouwt, P. (author)Botnets play an important role in modern Internet-related cybercrime. A botnet consists of a group of infected computers, referred to as bots. The bots are remotely controlled and deployed in malicious activities, such as DDoS attacks, spam, and espionage. Clever design of the botnet C&C (Command and Control) infrastructure, combined with the...doctoral thesis 2015

Fang, J. (author)The architecture diversity of many-core processors - with their different types of cores, and memory hierarchies - makes the old model of reprogramming every application for every platform infeasible. Therefore, inter-platform portability has become a desirable feature of programming models. While functional portability is ensured by standards...doctoral thesis 2014

Chiluka, N.J. (author)Due to its democratized nature, online social media (OSM) attracts millions of users to publish and share their content with friends as well as a wider audience at little cost. Such a vast user base and a wealth of content, however, presents its own challenges. First, the amount of user-generated content being uploaded in their repositories...doctoral thesis 2013

Ciobanu, C.B. (author)Processor clock frequencies and the related performance improvements recently stagnated due to severe power and thermal dissipation barriers. As a result, the additional transistors provided by new technology generations are turned into more processing elements on a chip and used for their specialization towards power efficiency. For data...doctoral thesis 2013

Sima, V.M. (author)In this dissertation, we address the problem of runtime adaptation of the application to its execution environment. A typical example is changing theprocessing element on which a computation is executed, considering the available processing elements in the system. This is done based on the information and instrumentation provided by the compiler...doctoral thesis 2012

Ludovici, D. (author)NoCs have been considered as the new design paradigm for large MPSoC systems in the past ten years. In the beginning NoCs were radically different compared to the current state of the art mainly due to the unexpected unique challenges that system designers had to solve with the evolving CMOS technology. In fact, various hidden physical level...doctoral thesis 2011

Marconi, T. (author)Runtime reconfigurable systems built upon devices with partial reconfiguration can provide reduction in overall hardware area, power efficiency, and economic cost in addition to the performance improvements due to better customization. However, the users of such systems have to be able to afford some additional costs compared to hardwired...doctoral thesis 2011

Dragomir, O.S. (author)The focus of this dissertation is on kernel loops (K-loops), which are loop nests that contain hardware mapped kernels in the loop body. In this thesis, we propose methods for improving the performance of such K-loops, by using standard loop transformations for exposing and exploiting the coarse grain loop level parallelism. We target a...doctoral thesis 2011

Hasan, L. (author)Biological sequence alignment is an important and challenging task in bioinformatics. Alignment may be defined as an arrangement of two or more DNA or protein sequences to highlight the regions of their similarity. Sequence alignment is used to infer the evolutionary relationship between a set of protein or DNA sequences. An accurate alignment...doctoral thesis 2011

Theodoropoulos, D.N. (author)In this dissertation, we propose a new approach for rapid development of multi-core immersive-audio systems. We study two popular immersive-audio techniques, namely the Beamforming and the Wave Field Synthesis (WFS). Beamforming utilizes microphone arrays to extract acoustic sources recorded in a noisy environment. WFS employs large loudspeaker...doctoral thesis 2011
