  text: In this paper, we study how AES key schedules can be reconstructed from decayed
    memory. This operation is a crucial and time consuming operation when trying to
    break encryption systems with cold-boot attacks. In software, the reconstruction
    of the AES master key can be performed using a recursive, branch-and-bound tree-search
    algorithm that exploits redundancies in the key schedule for constraining the
    search space. In this work, we investigate how this branch-and-bound algorithm
    can be accelerated with FPGAs. We translated the recursive search procedure to
    a state machine with an explicit stack for each recursion level and create optimized
    datapaths to accelerate in particular the processing of the most frequently accessed
    tree levels. We support two different decay models, of which especially the more
    realistic non-idealized asymmetric decay model causes very high runtimes in software.
    Our implementation on a Maxeler dataflow computing system outperforms a software
    implementation for this model by up to 27x, which makes cold-boot attacks against
    AES practical even for high error rates.

  text: Self-aware computing is a paradigm for structuring and simplifying the design
    and operation of computing systems that face unprecedented levels of system dynamics
    and thus require novel forms of adaptivity. The generality of the paradigm makes
    it applicable to many types of computing systems and, previously, researchers
    started to introduce concepts of self-awareness to multicore architectures. In
    our work we build on a recent reference architectural framework as a model for
    self-aware computing and instantiate it for an FPGA-based heterogeneous multicore
    running the ReconOS reconfigurable architecture and operating system. After presenting
    the model for self-aware computing and ReconOS, we demonstrate with a case study
    how a multicore application built on the principle of self-awareness, autonomously
    adapts to changes in the workload and system state. Our work shows that the reference
    architectural framework as a model for self-aware computing can be practically
    applied and allows us to structure and simplify the design process, which is essential
    for designing complex future computing systems.

  text: The ReconOS operating system for reconfigurable computing offers a unified
    multi-threaded programming model and operating system services for threads executing
    in software and threads mapped to reconfigurable hardware. The operating system
    interface allows hardware threads to interact with software threads using well-known
    mechanisms such as semaphores, mutexes, condition variables, and message queues.
    By semantically integrating hardware accelerators into a standard operating system
    environment, ReconOS allows for rapid design space exploration, supports a structured
    application development process and improves the portability of applications

  text: Reconfigurable architectures provide an opportunityto accelerate a wide range
    of applications, frequentlyby exploiting data-parallelism, where the same operations
    arehomogeneously executed on a (large) set of data. However, whenthe sequential
    code is executed on a host CPU and only dataparallelloops are executed on an FPGA
    coprocessor, a sufficientlylarge number of loop iterations (trip counts) is required,
    such thatthe control- and data-transfer overheads to the coprocessor canbe amortized.
    However, the trip count of large data-parallel loopsis frequently not known at
    compile time, but only at runtime justbefore entering a loop. Therefore, we propose
    to generate codeboth for the CPU and the coprocessor, and to defer the decisionwhere
    to execute the appropriate code to the runtime of theapplication when the trip
    count of the loop can be determinedjust at runtime. We demonstrate how an LLVM
    compiler basedtoolflow can automatically insert appropriate decision blocks intothe
    application code. Analyzing popular benchmark suites, weshow that this kind of
    runtime decisions is often applicable. Thepractical feasibility of our approach
    is demonstrated by a toolflowthat automatically identifies loops suitable for
    vectorization andgenerates code for the FPGA coprocessor of a Convey HC-1. Thetoolflow
    adds decisions based on a comparison of the runtimecomputedtrip counts to thresholds
    for specific loops and alsoincludes support to move just the required data to
    the coprocessor.We evaluate the integrated toolflow with characteristic loopsexecuted
    on different input data sizes.

  text: Stereo-matching algorithms recently received a lot of attention from the FPGA
    acceleration community. Presented solutions range from simple, very resource efficient
    systems with modest matching quality for small embedded systems to sophisticated
    algorithms with several processing steps, implemented on big FPGAs. In order to
    achieve high throughput, most implementations strongly focus on pipelining and
    data reuse between different computation steps. This approach leads to high efficiency,
    but limits the supported computation patterns and due the high integration of
    the implementation, adaptions to the algorithm are difficult. In this work, we
    present a stereo-matching implementation, that starts by offloading individual
    kernels from the CPU to the FPGA. Between subsequent compute steps on the FPGA,
    data is stored off-chip in on-board memory of the FPGA accelerator card. This
    enables us to accelerate the AD-census algorithm with cross-based aggregation
    and scanline optimization for the first time without algorithmic changes and for
    up to full HD image dimensions. Analyzing throughput and bandwidth requirements,
    we outline some trade-offs that are involved with this approach, compared to tighter
    integration of more kernel loops into one design.

  text: Cold-boot attacks exploit the fact that DRAM contents are not immediately
    lost when a PC is powered off. Instead the contents decay rather slowly, in particular
    if the DRAM chips are cooled to low temperatures. This effect opens an attack
    vector on cryptographic applications that keep decrypted keys in DRAM. An attacker
    with access to the target computer can reboot it or remove the RAM modules and
    quickly copy the RAM contents to non-volatile memory. By exploiting the known
    cryptographic structure of the cipher and layout of the key data in memory, in
    our application an AES key schedule with redundancy, the resulting memory image
    can be searched for sections that could correspond to decayed cryptographic keys;
    then, the attacker can attempt to reconstruct the original key. However, the runtime
    of these algorithms grows rapidly with increasing memory image size, error rate
    and complexity of the bit error model, which limits the practicability of the
    approach.In this work, we study how the algorithm for key search can be accelerated
    with custom computing machines. We present an FPGA-based architecture on a Maxeler
    dataflow computing system that outperforms a software implementation up to 205x,
    which significantly improves the practicability of cold-attacks against AES.

  text: In this paper we introduce “On-The-Fly Computing”, our vision of future IT
    services that will be provided by assembling modular software components available
    on world-wide markets. After suitable components have been found, they are automatically
    integrated, configured and brought to execution in an On-The-Fly Compute Center.
    We envision that these future compute centers will continue to leverage three
    current trends in large scale computing which are an increasing amount of parallel
    processing, a trend to use heterogeneous computing resources, and—in the light
    of rising energy cost—energy-efficiency as a primary goal in the design and operation
    of computing systems. In this paper, we point out three research challenges and
    our current work in these areas.

  text: "Although the benefits of FPGAs for accelerating scientific codes are widely
    acknowledged, the use of FPGA accelerators in scientific computing is not widespread
    because reaping these benefits requires knowledge of hardware design methods and
    tools that is typically not available with domain scientists. A promising but
    hardly investigated approach is to develop tool flows that keep the common languages
    for scientific code (C,C++, and Fortran) and allow the developer to augment the
    source code with OpenMPlike directives for instructing the compiler which parts
    of the application shall be offloaded the FPGA accelerator.\r\nIn this work we
    study whether the promise of effective FPGA acceleration with an OpenMP-like programming
    effort\r\ncan actually be held. Our target system is the Convey HC-1 reconfigurable
    computer for which an OpenMP-like\r\nprogramming environment exists. As case study
    we use an application from computational nanophotonics. Our results\r\nshow that
    a developer without previous FPGA experience could create an FPGA-accelerated
    application that is competitive to an optimized OpenMP-parallelized CPU version
    running on a two socket quad-core server. Finally, we discuss our experiences
    with this tool flow and the Convey HC-1 from a productivity and economic point
    of view."

  text: Due to the continuously shrinking device structures and increasing densities
    of FPGAs, thermal aspects have become the new focus for many research projects
    over the last years. Most researchers rely on temperature simulations to evaluate
    their novel thermal management techniques. However, the accuracy of the simulations
    is to some extent questionable and they require a high computational effort if
    a detailed thermal model is used.For experimental evaluation of real-world temperature
    management methods, often synthetic heat sources are employed. Therefore, in this
    paper we investigated the question if we can create significant rises in temperature
    on modern FPGAs to enable future evaluation of thermal management techniques based
    on experiments in contrast to simulations. Therefore, we have developed eight
    different heat-generating cores that use different subsets of the FPGA resources.
    Our experimental results show that, according to the built-in thermal diode of
    our Xilinx Virtex-5 FPGA, we can increase the chip temperature by 134 degree C
    in less than 12 minutes by only utilizing about 21% of the slices.

  text: One major obstacle for a wide spread FPGA usage in general-purpose computing
    is the development tool flow that requires much higher effort than for pure software
    solutions. Convey Computer promises a solution to this problem for their HC-1
    platform, where the FPGAs are conﬁgured to run as a vector processor and the software
    source code can be annotated with pragmas that guide an automated vectorization
    process. We investigate this approach for a stereo matching algorithm that has
    abundant parallelism and a number of different computational patterns. We note
    that for this case study the automated vectorization in its current state doesn’t
    hold its productivity promise. However, we also show that using the Vector Personality
    can yield a signiﬁcant speedups compared to CPU implementations in two of three
    investigated phases of the algorithm. Those speedups don’t match custom FPGA implementations,
    but can come with much reduced development effort.

  text: Today's design and operation principles and methods do not scale well with
    future reconfigurable computing systems due to an increased complexity in system
    architectures and applications, run-time dynamics and corresponding requirements.
    Hence, novel design and operation principles and methods are needed that possibly
    break drastically with the static ones we have built into our systems and the
    fixed abstraction layers we have cherished over the last decades. Thus, we propose
    a HW/SW platform that collects and maintains information about its state and progress
    which enables the system to reason about its behavior (self-awareness) and utilizes
    its knowledge to effectively and autonomously adapt its behavior to changing requirements
    (self-expression).To enable self-awareness, our compute nodes collect information
    using a variety of sensors, i.e. performance counters and thermal diodes, and
    use internal self-awareness models that process these information. For self-awareness,
    on-line learning is crucial such that the node learns and continuously updates
    its models at run-time to react to changing conditions. To enable self-expression,
    we break with the classic design-time abstraction layers of hardware, operating
    system and software. In contrast, our system is able to vertically migrate functionalities
    between the layers at run-time to exploit trade-offs between abstraction and optimization.This
    paper presents a heterogeneous multi-core architecture, that enables self-awareness
    and self-expression, an operating system for our proposed hardware/software platform
    and a novel self-expression method.

  text: Heterogeneous machines are gaining momentum in the High Performance Computing
    field, due to the theoretical speedups and power consumption. In practice, while
    some applications meet the performance expectations, heterogeneous architectures
    still require a tremendous effort from the application developers. This work presents
    a code generation method to port codes into heterogeneous platforms, based on
    transformations of the control flow into function calls. The results show that
    the cost of the function-call mechanism is affordable for the tested HPC kernels.
    The complete toolchain, based on the LLVM compiler infrastructure, is fully automated
    once the sequential specification is provided.

  text: While numerous publications have presented ring oscillator designs for temperature
    measurements a detailed study of the ring oscillator's design space is still missing.
    In this work, we introduce metrics for comparing the performance and area efficiency
    of ring oscillators and a methodology for determining these metrics. As a result,
    we present a systematic study of the design space for ring oscillators for a Xilinx
    Virtex-5 platform FPGA.
