▼ Microblogging is an increasingly popular form of social media. One of the most popular microblogging services is Twitter. The number of messages posted to Twitter on a daily basis is extremely large. Accordingly, it becomes hard for users to sort through these messages and find ones that interest them. Twitter offers search mechanisms but they are relatively simple and accordingly the results can be lacklustre. Through participation in the 2011 Text Retrieval Conference's Microblog Track, this thesis examines real-time ad hoc search using standard information retrieval approaches without microblog or Twitter specific modifications. It was found that using pseudo-relevance feedback based upon a language model derived from Twitter posts, called tweets, in conjunction with standard ranking methods is able to perform competitively with advanced retrieval systems as well as microblog and Twitter specific retrieval systems. Furthermore, possible modifications both Twitter specific and otherwise are discussed that would potentially increase retrieval performance. Twitter has also spawned an interesting phenomenon called hashtags. Hashtags are used by Twitter users to denote that their message belongs to a particular topic or conversation. Unfortunately, tweets have a 140 characters limit and accordingly all relevant hashtags cannot always be present in tweet. Thus, Twitter users cannot easily find tweets that do not contain hashtags they are interested in but should contain them. This problem is investigated in this thesis in three ways using learning methods. First, learning methods are used to determine if it is possible to discriminate between two topically different sets of a tweets. This thesis then investigates whether or not it is possible for tweets without a particular hashtag, but discusses the same topic as the hashtag, to be separated from random tweets. This case mimics the real world scenario of users having to sift through random tweets to find tweets that are related to a topic they are interested in. This investigation is performed by removing hashtags from tweets and attempting to distinguish those tweets from random tweets. Finally, this thesis investigates whether or not topically similar tweets can also be distinguished based upon a sub-topic. This was investigated in almost an identical manner to the second case. This thesis finds that topically distinct tweets can be distinguished but more importantly that standard learning methods are able to determine that a tweet with a hashtag removed should have that hashtag. In addition, this hashtag reconstruction can be performed well with very few examples of what a tweet with and without the particular hashtag should look like. This provides evidence that it may be possible to separate tweets a user may be interested from random tweets only using hashtags they are interested in. Furthermore, the success of the hashtag reconstruction also provides evidence that users do not misuse or abuse hashtags since hashtag presence was taken to be the ground…

▼ Avant cette étude, le processus anammox (oxydation anaérobie de l’ammonium) était uniquement étudié dans les usines de traitement des eaux usées et dans les milieux aquatiques, sédiments inclus. Cependant, rien n'était connu encore sur la distribution, la diversité, l'abondance et l'activité des bactéries anammox dans les écosystèmes terrestres. Dans cette étude, nous apportons l’évidence, par approche moléculaire, de la présence de bactéries anammox dans les sols de zones humides, les sédiments des marais, le profil de sol d’un Reductisol, des sols de rives de lacs, un sol sur Permafrost et un aquifère poreux. L'analyse phylogénétique des séquences du gène ARNr 16S a démontrée que les bactéries anammox présentes dans les écosystèmes terrestres sont affiliées à <i>Candidatus</i> ‘Brocadia’, ‘Kuenenia’, ‘Scalindua’, ‘Jettenia’ and ‘Anammoxoglobus’ ainsi qu’à deux groupes non identifiés. Ces candidats anammox étaient largement distribués dans les différents environnements terrestres indiquant une plus grande diversité que dans les colonnes d’eau des milieux marins. Les bactéries anammox n'étaient pas présentes dans tous les milieux et fractions de sol échantillonnés, l’analyse démontrant leur distribution hétérogène et leurs besoins écologiques spécifiques comme la présence d’interfaces oxique / anoxique à long terme et de composés azotés inorganiques. Nous avons quantifié les bactéries anammox dans ces différents environnements en développant une nouvelle approche qPCR spécifique anammox, et leur abondance variait de 10⁴ à 10⁶ copies / g de sol. Finalement, le Réductisol a été sélectionné pour réaliser une analyse détaillée de l’activité anammox le long du profil de sol par des expériences d'incubation à l’isotope ¹⁵N. Pour chaque date d'échantillonnage, une production de ²⁹N₂ était observée à toutes les profondeurs du Réductisol, démontrant la présence de bactéries anammox actives. La contribution d‘anammox à la production totale de N₂ était inférieure à 14%. Cette étude fournit la première preuve que les bactéries anammox sont présentes, diverses et actives dans les écosystèmes terrestres. Advisors/Committee Members: Michel (Dir.), Jakob (Codir.).

▼ Undesired, human behavior in public environments is an increasing issue in today’s society. The overload of security operators and law enforcement addresses the need for automatic detection of anomalous behavior. The EU-project ADABTS aims to facilitate the protection of EU citizens, property and infrastructure against threats of terrorism, crime and riots, by the automatic detection of abnormal human behaviour. At the Acoustics & Sonar department of TNO Defence and Safety, part of this problem is addressed by means of acoustical detection of anomalous events. The approach is based on ‘scanning’ public environments by applying beamforming on the outputs of an acoustical sensor array and applying classification algorithms for detecting specific sources. In this Master’s thesis, an initial step is taken with the development of a real-time beamforming system that delivers required sound parameters used in sound classification. A number of different beamforming methods have been considered, differing in performance and computational complexity. Conventional methods like Delay and Sum (DAS), possibly combined with the use of static, frequency-invariant windows, lack spatial resolution at especially lower frequencies and are unable of coping with multiple interfering sources. Other methods provide an improved performance on the cost of increased complexity. The method known as Minimum Variance Distortionless Response (MVDR) beamforming maintains a high spatial resolution at lower frequencies. Two main versions of this method are frequently used: a static (non-input-based) one and a dynamic (input-based) one. Static MVDR (SMVDR) is able to maintain performance at lower frequencies, but due to its static nature it does not add any extra value in multi-source environments. Dynamic MVDR (DMVDR), on the other hand, is partly capable of filtering away undesired coherent interferers and also has an improved spatial response in single-source environments. Its computational complexity, still, is an important bottleneck. The search for less intensive beamforming methods leads to a way of adaptive beamforming. Beamformers in which static beamforming and dynamic filtering are split in two different parts, are able to alleviate complexity. However, the need for adding extra elements to account for target-signal cancellation in multi-source environments destroys the computational advantages, making it unsuitable. The developed real-time application takes into account the intensive routines of DMVDR. Since the properties of the deployment platform are not known in advance, it is supplied with a mechanism for adapting to different and changing, available hardware resources such as available CPU-time, arithmetic units and memory. In this way it will always deliver the best possible solution, based on what the user is offering. Still, an extensive implementation process has led to a relatively fast execution of the algorithm. The system is supplied with a user interface for controlling a number of parameters and for obtaining the first… Advisors/Committee Members: Heusdens, R. (mentor), Hendriks, R.C.

▼ Modern real-time systems are becoming increasingly complex and requiring significant computational power to meet their demands. Since the increase in uniprocessor speed has slowed down in the last decade, multicore processors are now the preferred way to supply the increased performance demand of real-time systems. A significant amount of work in the real-time community has focused on scheduling solutions for multicore processors for both sequential and parallel real-time tasks. Even though such solutions are able to provide strict timing guarantees on the overall response time of real-time tasks, they rely on the assumption that the worst-case execution time (WCET) of each individual task is known. However, physical shared resources such as main memory and I/O are heavily employed in multicore processors. These resources are limited and therefore subject to contention. In fact, the execution time of one task when run in parallel with other tasks is significantly larger than the execution time of the same task when run in isolation. In addition, the presence of shared resources increases the timing unpredictability due to the conflicts generated by multiple cores. As a result, the adoption of multicore processors for real-time systems is dependent upon solving such sources of unpredictability. In this dissertation, we investigate memory bus contention. In particular, two main problems are associated with memory contention: (1) unpredictable behavior and (2) hindrance of performance. We show how to mitigate these two problems through scheduling. Scheduling is an attractive tool that can be easily integrated into the system without the need for hardware modifications. We adopt an execution model that exposes memory as a resource to the scheduling algorithm. Thus, the theory of real-time multiprocessor scheduling, that has seen significant advances in recent years, can be utilized to schedule both processor cores and memory. Since the real-time workload on multicore processors can be modeled as sequential or parallel tasks, we also study parallel task scheduling by taking memory time into account.

▼ Le contenu généré dans les médias sociaux comme Twitter permet aux utilisateurs d'avoir un aperçu rétrospectif d'évènement et de suivre les nouveaux développements dès qu'ils se produisent. Cependant, bien que Twitter soit une source d'information importante, il est caractérisé par le volume et la vélocité des informations publiées qui rendent difficile le suivi de l'évolution des évènements. Pour permettre de mieux tirer profit de ce nouveau vecteur d'information, deux tâches complémentaires de recherche d'information dans les médias sociaux ont été introduites : la génération de résumé rétrospectif qui vise à sélectionner les tweets pertinents et non redondant récapitulant "ce qui s'est passé" et l'envoi des notifications prospectives dès qu'une nouvelle information pertinente est détectée. Notre travail s'inscrit dans ce cadre. L'objectif de cette thèse est de faciliter le suivi d'événement, en fournissant des outils de génération de synthèse adaptés à ce vecteur d'information. Les défis majeurs sous-jacents à notre problématique découlent d'une part du volume, de la vélocité et de la variété des contenus publiés et, d'autre part, de la qualité des tweets qui peut varier d'une manière considérable. La tâche principale dans la notification prospective est l'identification en temps réel des tweets pertinents et non redondants. Le système peut choisir de retourner les nouveaux tweets dès leurs détections où bien de différer leur envoi afin de s'assurer de leur qualité. Dans ce contexte, nos contributions se situent à ces différents niveaux : Premièrement, nous introduisons Word Similarity Extended Boolean Model (WSEBM), un modèle d'estimation de la pertinence qui exploite la similarité entre les termes basée sur le word embedding et qui n'utilise pas les statistiques de flux. L'intuition sous- jacente à notre proposition est que la mesure de similarité à base de word embedding est capable de considérer des mots différents ayant la même sémantique ce qui permet de compenser le non-appariement des termes lors du calcul de la pertinence. Deuxièmement, l'estimation de nouveauté d'un tweet entrant est basée sur la comparaison de ses termes avec les termes des tweets déjà envoyés au lieu d'utiliser la comparaison tweet à tweet. Cette méthode offre un meilleur passage à l'échelle et permet de réduire le temps d'exécution. Troisièmement, pour contourner le problème du seuillage de pertinence, nous utilisons un classificateur binaire qui prédit la pertinence. L'approche proposée est basée sur l'apprentissage supervisé adaptatif dans laquelle les signes sociaux sont combinés avec les autres facteurs de pertinence dépendants de la requête. De plus, le retour des jugements de pertinence est exploité pour re-entrainer le modèle de classification. Enfin, nous montrons que l'approche proposée, qui envoie les notifications en temps réel, permet d'obtenir des performances prometteuses en termes de qualité (pertinence et nouveauté) avec une faible latence alors que les approches de l'état de l'art tendent à favoriser la qualité au… Advisors/Committee Members: Dousset, Bernard (thesis director), Boughanem, Mohand (thesis director).

▼ Social media gain worldwide popularity and their volumes are in rapid growth. Blogs and microblogs are two typical types of social media. By February 2011, there had been over 156 million public blogs in existence and the volume of blogosphere is predicted to double about every 5.5 months. Twitter, a microblogging service, has a daily volume of over 340 million tweets by 2012. With such an overwhelming amount of information in blogosphere and micro-blogosphere, advanced information retrieval techniques are needed. In this thesis, I tackle two advanced information retrieval problems: faceted blog distillation over blogosphere and real-time tweet ad-hoc retrieval over micro-blogosphere. For faceted blog distillation, users aim at retrieving the blogs that are not only relevant to queries but also exhibit some qualities. Six aspects of quality (called facets) are considered: opinionated vs. factual, personal vs. official and in-depth vs. shallow. Opinionated blogs provide the blog posts that contain relevant opinions to queries while factual blogs consist of the posts that describe the topics of queries without opinionated contents. The posts in personal blogs depict the topics related to the personal experiences of bloggers while those in official blogs deliver commercial purposes of bloggers. In-depth blogs provide deep analysis about the topics of interest while the posts in shallow blogs simply mention the topics, without analyzing the implications of the provided information. Faceted blog distillation consists of three sub-problems: opinionated and factual blog distillation, personal and official blog distillation, and in-depth and shallow blog distillation. For opinionated and factual blog distillation, I propose a classification-based method to identify the opinions relevant to queries in terms of syntax and semantics. For personal and official blog distillation, I propose two categories of methods: classification based and topic modeling based. All proposed methods effectively differentiate personal blog posts from official blog posts. For in-depth and shallow blog distillation, I propose a measurement to compute the query-oriented depth of blog posts. I also discuss the relationships among facets. The proposed techniques are evaluated by using 220 TREC 2006-2010 queries over two TREC collections: Blogs06 and Blogs08. The proposed methods significantly outperform the best known results for faceted blog distillation. For real-time tweet ad-hoc retrieval, users wish to see the tweets that are not only relevant to queries but also be most recent ones. I propose a two-phase approach to address this problem. Tweets can be categorized into two types. One type consists of short messages not containing any URL of a web page. The other type has at least one URL of a web page in addition to a short message. These two types of tweets have different structures. In the first phase, I propose a learning-to-rank method to rank tweets using the divide-and-conquer strategy to address the structural difference of tweets.

▼ Increasing size and prevalence of real time information have become important characteristics of databases found on the internet. Due to changing information, the relevancy ranking of the search results also changes. Current methods in information retrieval, which are based on offline indexing, are not efficient in such dynamic search spaces and cannot quickly provide the most current results. Due to the explosive growth of the internet, stove-piped approaches for dealing with dynamism by simply employing large computational resources are ultimately not scalable. A new processing methodology that incorporates intelligent resource allocation strategies is required. Also, modeling the dynamism in the search space in real time is essential for effective resource allocation. In order to support multi-grained dynamic resource allocation, we propose to use a partial processing approach that uses anytime algorithms to process the documents in multiple steps. At each successive step, a more accurate approximation of the final similarity values of the documents is produced. Resource allocation algorithm use these partial results to select documents for processing, decide on the number of processing steps and the computation time allocated for each step. We validate the processing paradigm by demonstrating its viability with image documents. We design an anytime image algorithm that uses a combination of wavelet transforms and machine learning techniques to map low level visual features to higher level concepts. Experimental validation is done by implementing the image algorithm within an established multiagent information retrieval framework called I-FGM. We also formulate a multiagent resource allocation framework for design and performance analysis of resource allocation with partial processing. A key aspect of the framework is modeling changes in the search space as external and internal dynamism using a grid-based search space model. The search space model divides the documents or candidates into groups based on its partial-value and portion processed. Hence the changes in the search space can be effectively represented in the search space model as flow of agents and candidates between the grids. Using comparative experimental studies and detailed statistical analysis we validate the search space model and demonstrate the effectiveness of the resource allocation framework.

▼ Endogenous Fluorescence Lifetime Imaging (FLIM) is a noninvasive technique that has been explored with promising results in a wide range of biomedical applications, including clinical diagnosis. A central issue for the translation of FLIM into the medical field is the development of a robust, fast and cost-effective FLIM instrumentation suitable for in vivo tissue imaging. This thesis directly addressed some of the technical limitations that must be overcome to enable clinical applications of FLIM. The following specific aims were accomplished. First, endogenous FLIM imaging and high-resolution reflectance confocal microscopy (RCM) were integrated into a multimodal bench-top optical system. This multimodal system was used to image oral epithelial cancer in a hamster cheek pouch model. Second, an endoscopic system for fast (0.5-4 frames/second) endogenous wide-field FLIM imaging of oral lesions was developed. The FLIM endoscope system is being evaluate at Texas A&M University College of Dentistry, where more than 80 patients presenting oral lesions suspected of pre-cancer or cancer have been imaged up to date. Third, a novel fluorescence lifetime estimation algorithm was developed to achieve robust, accurate, and real-time fluorescence lifetime estimation. This algorithm is enabling real-time FLIM image processing and visualization during the endoscopic examination of patients with suspicious oral lesions. Finally, the endoscopic endogenous FLIM data from suspicious oral lesions collected at the Texas A&M College of Dentistry was used to develop machine learning algorithms for automated identification of precancerous and cancerous lesions from benign oral epithelial lesions. Our results indicate that endogenous FLIM endoscopy can detect oral epithelial pre-cancer and cancer from a wider range of benign conditions, with levels of sensitivity and specificity above 85%. Altogether, this work has demonstrated the potentials of endogenous FLIM endoscopy as a clinical tool for early detection of oral epithelial cancer.

▼ Conventional hard real-time scheduling is often overly pessimistic due to the worst case execution time estimation. The pessimism can be mitigated by exploiting imprecise computing in applications where occasional small errors are acceptable. This leverage is investigated in a few previous works, which are restricted to preemptive cases. We study how to make use of imprecise computing in uniprocessor non-preemptive real-time scheduling, which is known to be more difficult than its preemptive counterpart. Several heuristic algorithms are developed for periodic tasks with independent or cumulative errors due to imprecision. Simulation results show that the proposed techniques can significantly improve task schedulability and achieve desired accuracy– schedulability tradeoff. The benefit of considering imprecise computing is further confirmed by a prototyping implementation in Linux system. Mixed-criticality system is a popular model for reducing pessimism in real-time scheduling while providing guarantee for critical tasks in presence of unexpected overrun. However, it is controversial due to some drawbacks. First, all low-criticality tasks are dropped in high-criticality mode, although they are still needed. Second, a single high-criticality job overrun leads to the pessimistic high-criticality mode for all high-criticality tasks and consequently resource utilization becomes inefficient. We attempt to tackle aforementioned two limitations of mixed-criticality system simultaneously in multiprocessor scheduling, while those two issues are mostly focused on uniprocessor scheduling in several recent works. We study how to achieve graceful degradation of low-criticality tasks by continuing their executions with imprecise computing or even precise computing if there is sufficient utilization slack. Schedulability conditions under this Variable-Precision Mixed-Criticality (VPMC) system model are investigated for partitioned scheduling and global fpEDF-VD scheduling. And a deferred switching protocol is introduced so that the chance of switching to high-criticality mode is significantly reduced. Moreover, we develop a precision optimization approach that maximizes precise computing of low-criticality tasks through 0-1 knapsack formulation. Experiments are performed through both software simulations and Linux proto- typing with consideration of overhead. Schedulability of the proposed methods is studied so that the Quality-of-Service for low-criticality tasks is improved with guarantee of satisfying all deadline constraints. The proposed precision optimization can largely reduce computing errors compared to constantly executing low-criticality tasks with imprecise computing in high-criticality mode.

▼ Functional Reactive Programming (FRP) is a declarative approach for modeling and building reactive systems. FRP has been shown to be an expressive formalism for building applications of computer graphics, computer vision, robotics, etc. Priority-based FRP (P-FRP) is a formalism that allows preemption of executing programs and guarantees real-time response. Since functional programs cannot maintain state and mutable data, changes made by programs that are preempted have to be rolled back. Hence in P-FRP, a higher priority task can preempt the execution of a lower priority task, but the preempted lower priority task will have to restart after the higher priority task has completed execution. This execution paradigm is called Abort-and-Restart (AR). Current real-time research is focused on preemptive of non-preemptive models of execution and several state-of-the-art methods have been developed to analyze the real-time guarantees of these models. Unfortunately, due to its transactional nature where preempted tasks are aborted and have to restart, the execution semantics of P-FRP does not fit into the standard definitions of preemptive or non-preemptive execution, and the research on the standard preemptive and non-preemptive may not applicable for the P-FRP AR model. Out of many research areas that P-FRP may demands, we focus on task scheduling which includes task and system modeling, priority assignment, schedulability analysis, response time analysis, improved P-FRP AR models, algorithms and corresponding software. In this work, we review existing results on P-FRP task scheduling and then present our research contributions: (1) a tighter feasibility test interval regarding the task release offsets as well as a linked list based algorithm and implementation for scheduling simulation; (2) P-FRP with software transactional memory-lazy conflict detection (STM-LCD); (3) a non-work-conserving scheduling model called Deferred Start; (4) a multi-mode P-FRP task model; (5) SimSo-PFRP, the P-FRP extension of SimSo - a SimPy-based, highly extensible and user friendly task generator and task scheduling simulator.

▼ Early and accurate diagnosis of oak wilt, caused by Ceratocystis fagacearum, is important when disease control action is planned. When laboratory diagnosis is needed, standard isolation protocols that are used rely on high quality samples and require up to 14 days for incubation. New methods, involving the use of polymerase chain reaction (PCR) have the potential to offer faster and more reliable plant disease diagnostics. The purpose of this thesis was to 1) compare the use of a nested PCR and real-time PCR protocol to detect C. fagacearum in sapwood drill shavings using published isolation methods and 2) develop standard sampling and processing guidelines for oak wilt diagnostics using the protocols, and 3) test and evaluate the use of the protocols in operational plant disease diagnostic clinics. All assays were performed on samples obtained from Quercus rubra/Q. ellipsoidalis (red oak), Q. macrocarpa (bur oak), and Q. alba (white oak) trees in Minnesota. Drill shavings were collected from actively wilting oak trees as well as from tissues taken the year following branch or whole tree death. Between the assays tested (nested PCR, real-time PCR, and isolation), the nested PCR assay resulted in the highest estimated probability of C. fagacearum detection for branch segments sampled from actively wilting oak trees. For bur and white oak branches that had been dead for >= 1 year, the pathogen was detected using nested PCR (55 and 87% of branch segments, respectively) and real-time PCR (19%, white oak only), while isolation was not able to detect the pathogen in any branch segments. All three detection methods were able to detect the fungus in main stem samples of red oaks with a streaking cambium, however, the molecular protocols resulted in more frequent pathogen detection. Only the molecular assays detected the pathogen in sapwood samples underlying the remnants of C. fagacearum sporulation mats on main stem samples of red oak trees. The fungus was not detected by either technique in branch segments obtained from healthy oaks (controls). Inter-laboratory testing of the nested PCR and real-time PCR protocols supported the previously described differences in assay reliability. Overall, the comparison of traditional isolation and nested PCR by the University of Minnesota Plant Disease Clinic resulted in the same number of trees testing positive for the pathogen by both detection methods. A comparison of isolation methods and real-time PCR was completed by the University of Wisconsin-Madison Plant Disease Diagnostic Clinic, which resulted in a higher rate of detection using isolation methods.

▼ Public transit agencies often struggle with service reliability issues; when a bus or train does not arrive on time, passengers become frustrated and may be less likely to choose transit for future trips. To address reliability problems, transit authorities increasingly provide real-time vehicle location and arrival information to riders via web-enabled and mobile devices. Although prior studies have found several benefits of offering this information to passengers, researchers have had difficulty determining if real-time information affects ridership levels. Therefore, the objective of this dissertation is to quantify the impact of real-time information on public transit ridership. Statistical and econometric methods were used to analyze passenger behavior in three American cities that share a common real-time information platform: New York City, Tampa, and Atlanta. New York City was the setting for a natural experiment in which real-time bus information was gradually launched on a borough-by-borough basis over a three year period. Panel regression techniques were used to evaluate route-level bus ridership while controlling for changes in transit service, fares, local socioeconomic conditions, weather, and other factors. In Tampa, a behavioral experiment was performed with a before-after control group design in which access to real-time bus information was the treatment variable and web-based surveys measured behavior changes over a three month period. In Atlanta, a methodology to combine smart card fare collection data with web-based survey responses was developed to quantify changes in transit travel of individual riders in a before-after study. In summary, each study utilized different data sources and quantitative methods to assess changes in transit ridership. The results varied between cities and suggest that the impact of real-time information on transit travel is greatest in locations that have high levels of transit service. These findings have immediate implications for decision-makers at transit agencies, who often face pressure to increase ridership with limited resources.

▼ Elemental digital beamforming offers increased flexibility for multi-function radio frequency (RF) systems supporting radar and communications applications. As fully digital arrays, components, and subsystems are becoming more affordable in the military and commercial industries, analog components such as phase shifters, filters, and mixers have begun to be replaced by digital circuits which presents efficiency challenges in power constrained scenarios. Furthermore, multi-function radar and communications systems are exploiting the multiple simultaneous beam capability provided by digital at every element beamforming. Along with further increasing data samples rates and increasing instantaneous bandwidths (IBW), real time processing in the digital domain has become a challenge due to the amount of data produced and processed in current systems. These arrays generate hundreds of gigabits per second of data throughput or more which is costly to send off-chip to an adjunct processor fundamentally limiting the overall performance of an RF array system. In this dissertation, digital filtering techniques and architectures are described which calibrate and beamform both narrowband and wideband RF arrays on receive. The techniques are shown to optimize one or many parameters of the digital transceiver system to improve the overall system efficiency. Digitally beamforming in the beamspace is shown to further increase the processing efficiency of an adaptive system compared to state of the art frequency domain approaches by minimizing major processing bottlenecks of generating adaptive filter coefficients. The techniques discussed are compared and contrasted across different hardware processor modules including field-programmable gate arrays (FPGAs), graphical processing units (GPUs), and central processing units (CPUs).

▼ Emerging safety-critical systems require high-performance data-parallel architectures and, problematically, ones that can guarantee tight and safe worst-case execution times. Given the complexity of existing architectures like GPUs, it is unlikely that sufficiently accurate models and algorithms for timing analysis will emerge in the foreseeable future. This motivates a clean-slate approach to designing a real-time data-parallel architecture. In this work I present Sim-D: a wide-SIMD architecture for hard real-time systems. Similar to GPUs, Sim-D performs hardware strip-mining to schedule the work for a compute kernel in entities called work-groups. Sim-D schedules the work for each work-group as a sequence of uninterruptible access- and execute program phases, interleaving the phases of two work-groups. By providing performance isolation between the memory- and compute resources, the execution time of each phase can be tightly bound through static analysis. I present a predictable closed-page DRAM controller that processes requests for large 1D- and 2D blocks of data, as well as indirect indexed transfers. These large transfers coalesce the data requests of a whole work-group. For a linear 4KiB transfer over a 64-bit data bus, the utilisation provably exceeds 78% for DDR4-3200AA DRAM. For 2D blocks, a well-chosen tiling configuration can achieve near-similar efficiency. I show that bounds on the execution time of indexed transfers are pessimistic by nature, but propose a novel snoopy indexed transfer mechanism that permits more reasonable bounds when the buffer size is limited. Finally, I present a worst-case execution time calculation algorithm for Sim-D. This algorithm is paired with two hardware work-group scheduling policies that deterministically reduce run-time variance. The worst-case execution time analysis algorithm combines static control flow analysis with a simulation-based cost model for execution and DRAM transfers. Its key novelty is the addition of a stage that considers work-group scheduling effects. I show that the work-group scheduling policies degrade performance on average by 8.9%, but permit the calculation of worst-case execution time bounds that are tight within 14.3% on average for benchmarks that avoid inefficient indexed transfers.

Sim-D schedules the work for each work-group as a sequence of uninterruptible access- and execute program phases, interleaving the phases of two work-groups. By providing performance isolation between the memory- and compute resources, the execution time of each phase can be tightly bound through static analysis. I present a predictable closed-page DRAM controller that processes requests for large 1D- and 2D blocks of data, as well as indirect indexed transfers. These large transfers coalesce the data requests of a whole work-group. For a linear 4KiB transfer over a 64-bit data bus, the utilisation provably exceeds 78% for DDR4-3200AA DRAM. For 2D blocks, a well-chosen tiling configuration can achieve near-similar efficiency. I show that bounds on the execution time of indexed transfers are pessimistic by nature, but propose a novel snoopy indexed transfer mechanism that permits more reasonable bounds when the buffer size is limited. Finally, I present a worst-case execution time calculation algorithm for Sim-D. This algorithm is paired with two hardware work-group scheduling policies that deterministically reduce run-time variance. The worst-case execution time analysis algorithm combines static control flow analysis with a simulation-based cost model for execution and DRAM transfers. Its key novelty is the addition of a stage that considers work-group scheduling effects. I show that the work-group scheduling policies degrade performance on average by 8.9%, but permit the calculation of worst-case execution time bounds that are tight within 14.3% on average for benchmarks that avoid inefficient indexed transfers.
