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.

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: "With self-reinforced thermoplastics, it is possible to produce composite
systems that, unlike traditional fiber composite materials, do not contain any
foreign fibers for reinforcement. Instead, thermoplastic fibers or tapes, for
example made of PP or PE, are used in an identical matrix. This opens up a high
potential for lightweight construction and, at the same time, very good recyclability.\r\n"

text: "Based on research results from the Collaborative Research Center Transregio
30, it is shown how composites made of self-reinforced, partially crystalline
or highly stretched amorphous foils and fabrics for lightweight construction applications
can be produced and which properties can be achieved. A locally differential,
thermo-mechanical process control can be varied very efficiently, and thus graded
properties can be set in the sense of functionalization.\r\n"

text: Calcium-Silicate-Hydrates (C-S-H) are the main binding phases in most concrete
which is the primarily used composite construction material in the world. However,
a big lack is cleaving between the actual knowledge about C-S-H, compared to what
could be reached using state-of-the-art technologies of modern research. In this
article, the formation of a C-S-H phase on a native oxide covered silicon wafer
is investigated by means of in-situ attenuated total reflection infrared (ATR-IR)
and ex-situ surface-enhanced Raman spectroscopy (SERS). The total thickness of
the C-S-H phase is determined by X-ray photoelectron spectroscopy (XPS) to be
3 nm. The formation appears to be reversible depending on the environment pH value
and can be performed at room temperature. Based on density functional theory (DFT)
calculations, it is shown that the C-S-H phase in the presence of water will change
its chemical composition in order to reach the thermodynamic ground state of the
system. This change is achieved by a metal-proton exchange reaction. The stoichiometry
of these metal-proton exchange reactions is nearly independent of the environment
pH value. Electrokinetic measurements yield isoelectric points of 2.0 and 2.6
for the native oxide covered silicon wafer (SiO2) and the C-S-H phase. This is
consistent with a predominance of Si-O sites at the C-S-H/water interface. (C)

text: SUMMARYWe introduce a material model for
the simulation of polycrystalline materials undergoing solid‐to‐solid phase‐transformations.
As a basis, we present a scalar‐valued phase‐transformation model where a Helmholtz
free energy function depending on volumetric and deviatoric strain measures is
assigned to each phase. The analysis of the related overall Gibbs energy density
allows for the calculation of energy barriers. With these quantities at hand,
we use a statistical‐physics‐based approach to determine the resulting evolution
of volume fractions. Though the model facilitates to take into account an arbitrary
number of solid phases of the underlying material, we restrict this work to the
simulation of phase‐transformations between an austenitic parent phase and a martensitic
tension and compression phase. The scalar model is embedded into a computational
micro‐sphere formulation in view of the simulation of three‐dimensional boundary
value problems. The final modelling approach necessary for macroscopic simulations
is accomplished by a finite element formulation, where the local material behaviour
at each integration point is governed by the response of the micro‐sphere model.Copyright

text: Collective spin excitations form a fundamental class of excitations in magnetic
materials. As their energy reaches down to only a few meV, they are present at
all temperatures and substantially influence the properties of magnetic systems.
To study the spin excitations in solids from first principles, we have developed
a computational scheme based on many-body perturbation theory within the full-potential
linearized augmented plane-wave (FLAPW) method. The main quantity of interest
is the dynamical transverse spin susceptibility or magnetic response function,
from which magnetic excitations, including single-particle spin-flip Stoner excitations
and collective spin-wave modes as well as their lifetimes, can be obtained. In
order to describe spin waves we include appropriate vertex corrections in the
form of a multiple-scattering T matrix, which describes the coupling of electrons
and holes with different spins. The electron–hole interaction incorporates the
screening of the many-body system within the random-phase approximation. To reduce
the numerical cost in evaluating the four-point T matrix, we exploit a transformation
to maximally localized Wannier functions that takes advantage of the short spatial
range of electronic correlation in the partially filled d or f orbitals of magnetic
materials. The theory and the implementation are discussed in detail. In particular,
we show how the magnetic response function can be evaluated for arbitrary k points.
This enables the calculation of smooth dispersion curves, allowing one to study
fine details in the k dependence of the spin-wave spectra. We also demonstrate
how spatial and time-reversal symmetry can be exploited to accelerate substantially
the computation of the four-point quantities. As an illustration, we present spin-wave
spectra and dispersions for the elementary ferromagnet bcc Fe, B2-type tetragonal
FeCo, and CrO2 calculated with our scheme. The results are in good agreement with
available experimental data.
