  text: "Monte-Carlo Tree Search (MCTS) is a class of simulation-based search algorithms.
    It brought about great success in the past few years regarding the evaluation
    of deterministic two-player games such as the Asian board game Go.\r\n\r\nIn this
    thesis, we present a parallelization of the most popular MCTS variant for large
    HPC compute clusters that efficiently shares a single game tree representation
    in a distributed memory environment and scales up to 128 compute nodes and 2048
    cores. It is hereby one of the most powerful MCTS parallelizations to date.\r\n\r\nIn
    order to measure the impact of our parallelization on the search quality and remain
    comparable to the most advanced MCTS implementations to date, we implemented it
    in a state-of-the-art Go engine Gomorra, making it competitive with the strongest
    Go programs in the world.\r\n\r\nWe further present an empirical comparison of
    different Bayesian ranking systems when being used for predicting expert moves
    for the game of Go and introduce a novel technique for automated detection and
    analysis of evaluation uncertainties that show up during MCTS searches."

  text: "Reconfigurable circuit devices have opened up a fundamentally new way of
    creating adaptable systems. Combined with artificial evolution, reconfigurable
    circuits allow an elegant adaptation approach to compensating for changes in the
    distribution of input data, computational resource errors, and variations in resource
    requirements. Referred to as ``Evolvable Hardware'' (EHW), this paradigm has yielded
    astonishing results for traditional engineering challenges and has discovered
    intriguing design principles, which have not yet been seen in conventional engineering.\r\n\r\nIn
    this thesis, we present new and fundamental work on Evolvable Hardware motivated
    by the insight that Evolvable Hardware needs to compensate for events with different
    change rates. To solve the challenge of different adaptation speeds, we propose
    a unified adaptation approach based on multi-objective evolution, evolving and
    propagating candidate solutions that are diverse in objectives that may experience
    radical changes.\r\n\r\nFocusing on algorithmic aspects, we enable Cartesian Genetic
    Programming (CGP) model, which we are using to encode Boolean circuits, for multi-objective
    optimization by introducing a meaningful recombination operator. We improve the
    scalability of CGP by objectives scaling, periodization of local- and global-search
    algorithms, and the automatic acquisition and reuse of subfunctions using age-
    and cone-based techniques. We validate our methods on the applications of adaptation
    of hardware classifiers to resource changes, recognition of muscular signals for
    prosthesis control and optimization of processor caches."

  text: 'Handling run-time dynamics on embedded system-on-chip architectures has become
    more challenging over the years. On the one hand, the impact of workload and physical
    dynamics on the system behavior has dramatically increased. On the other hand,
    embedded architectures have become more complex as they have evolved from single-processor
    systems over multi-processor systems to hybrid multi-core platforms.Static design-time
    techniques no longer provide suitable solutions to deal with the run-time dynamics
    of today''s embedded systems. Therefore, system designers have to apply run-time
    solutions, which have hardly been investigated for hybrid multi-core platforms.In
    this thesis, we present fundamental work in the new area of run-time management
    on hybrid multi-core platforms. We propose a novel architecture, a self-adaptive
    hybrid multi-core system, that combines heterogeneous processors, reconfigurable
    hardware cores, and monitoring cores on a single chip. Using self-adaptation on
    thread-level, our hybrid multi-core systems can effectively perform performance
    and thermal management autonomously at run-time. '

  text: FPGAs, systems on chip and embedded systems are nowadays irreplaceable. They
    combine the computational power of application specific hardware with software-like
    flexibility. At runtime, they can adjust their functionality by downloading new
    hardware modules and integrating their functionality. Due to their growing capabilities,
    the demands made to reconfigurable hardware grow. Their deployment in increasingly
    security critical scenarios requires new ways of enforcing security since a failure
    in security has severe consequences. Aside from financial losses, a loss of human
    life and risks to national security are possible. With this work I present the
    novel and groundbreaking concept of proof-carrying hardware. It is a method for
    the verification of properties of hardware modules to guarantee security for a
    target platform at runtime. The producer of a hardware module delivers based on
    the consumer's safety policy a safety proof in combination with the reconfiguration
    bitstream. The extensive computation of a proof is a contrast to the comparatively
    undemanding checking of the proof. I present a prototype based on open-source
    tools and an abstract FPGA architecture and bitstream format. The proof of the
    usability of proof-carrying hardware provides the evaluation of the prototype
    with the exemplary application of securing combinational and bounded sequential
    equivalence of reference monitor modules for memory safety.

  text: FPGAs, System on Chips und eingebettete Systeme sind heutzutage kaum mehr
    wegzudenken. Sie kombinieren die Rechenleistung von spezialisierter Hardware mit
    einer Software-ähnlichen Flexibilität. Zur Laufzeit können sie ihre Funktionalität
    anpassen, indem sie online neue Hardware Module beziehen und deren Funktionalität
    integrieren. Mit der Leistung wachsen auch die Anforderungen an rekonfigurierbare
    Hardware. Ihr Einsatz in immer sicherheitskritischeren Szenarien erfordert neue
    Wege um Sicherheit zu gewährleisten, da ein Versagen der Sicherheit gravierende
    Folgen mit sich bringt. Neben finanziellen Verlusten sind auch der Verlust von
    Menschenleben oder Einbußen in der nationalen Sicherheit denkbar. In dieser Arbeit
    stelle ich das neue und wegweisende Konzept der beweistragenden Hardware vor.
    Es ist eine Methode zur Verifizierung von Eigenschaften von Hardware Modulen um
    die Sicherheit der Zielplatformen zur Laufzeit zu garantieren. Der Produzent eines
    Hardware Moduls liefert, basierend auf den Sicherheitsbestimmungen des Konsumenten,
    einen Beweis der Sicherheit mit dem Rekonfigurierungsbitstrom. Die aufwendige
    Berechnung des Beweises steht im Kontrast zu der vergleichsweise unaufwendigen
    Überprüfung durch den Konsumenten. Ich präsentiere einen Prototypen basierend
    auf Open Source Werkzeugen und einer eigenen abstrakten FPGA Architektur samt
    Bitstromformat. Den Nachweis über die Nutzbarkeit von beweistragender Hardware
    erbringt die Evaluierung des Prototypen zur beispielhaften Anwendung der Sicherung
    von kombinatorischer und begrenzt sequenzieller Äquivalenz von Referenzmonitor-Modulen
    zur Speichersicherheit.

  text: "The paradigm shift towards many-core parallelism is accompanied by two fundamental
    questions: how should the many processors on a single die communicate to each
    other and what are suitable programming models for these novel architectures?
    In this thesis, the author tackles both questions by reviewing the reconfigurable
    mesh model of massively parallel computation for many-cores.\r\n\r\nThe book presents
    the design, implementation and evaluation of a many-core architecture that is
    based on the execution principles and communication infrastructure of the reconfigurable
    mesh. This work fundamentally rests on FPGA implementations and shows that reconfigurable
    mesh processors with hundreds of autonomous cores are feasible. Several case studies
    demonstrate the effectiveness of programming and illustrate why the reconfigurable
    mesh is a promising model for many-cores."
