text: Many modern compute nodes are heterogeneous multi-cores that integrate several
CPU cores with fixed function or reconfigurable hardware cores. Such systems need
to adapt task scheduling and mapping to optimise for performance and energy under
varying workloads and, increasingly important, for thermal and fault management
and are thus relevant targets for self-aware computing. In this chapter, we take
up the generic reference architecture for designing self-aware and self-expressive
computing systems and refine it for heterogeneous multi-cores. We present ReconOS,
an architecture, programming model and execution environment for heterogeneous
multi-cores, and show how the components of the reference architecture can be
implemented on top of ReconOS. In particular, the unique feature of dynamic partial
reconfiguration supports self-expression through starting and terminating reconfigurable
hardware cores. We detail a case study that runs two applications on an architecture
with one CPU and 12 reconfigurable hardware cores and present self-expression
strategies for adapting under performance, temperature and even conflicting constraints.
The case study demonstrates that the reference architecture as a model for self-aware
computing is highly useful as it allows us to structure and simplify the design
process, which will be essential for designing complex future compute nodes. Furthermore,
ReconOS is used as a base technology for flexible protocol stacks in Chapter 10,
an approach for self-aware computing at the networking level.

text: A broad spectrum of applications can be accelerated by offloading computation
intensive parts to reconfigurable hardware. However, to achieve speedups, the
number of loop it- erations (trip count) needs to be sufficiently large to amortize
offloading overheads. Trip counts are frequently not known at compile time, but
only at runtime just before entering a loop. Therefore, we propose to generate
code for both the CPU and the coprocessor, and defer the offloading decision to
the application runtime. We demonstrate how a toolflow, based on the LLVM compiler
framework, can automatically embed dynamic offloading de- cisions into the application
code. We perform in-depth static and dynamic analysis of pop- ular benchmarks,
which confirm the general potential of such an approach. We also pro- pose to
optimize the offloading process by decoupling the runtime decision from the loop
execution (decision slack). The feasibility of our approach is demonstrated by
a toolflow that automatically identifies suitable data-parallel loops and generates
code for the FPGA coprocessor of a Convey HC-1. We evaluate the integrated toolflow
with representative loops executed for different input data sizes.

text: The use of heterogeneous computing resources, such as Graphic Processing Units
or other specialized coprocessors, has become widespread in recent years because
of their per- formance and energy efficiency advantages. Approaches for managing
and scheduling tasks to heterogeneous resources are still subject to research.
Although queuing systems have recently been extended to support accelerator resources,
a general solution that manages heterogeneous resources at the operating system-
level to exploit a global view of the system state is still missing.In this paper
we present a user space scheduler that enables task scheduling and migration on
heterogeneous processing resources in Linux. Using run queues for available resources
we perform scheduling decisions based on the system state and on task characterization
from earlier measurements. With a pro- gramming pattern that supports the integration
of checkpoints into applications, we preempt tasks and migrate them between three
very different compute resources. Considering static and dynamic workload scenarios,
we show that this approach can gain up to 17% performance, on average 7%, by effectively
avoiding idle resources. We demonstrate that a work-conserving strategy without
migration is no suitable alternative.

text: Parametrization based methods have recently become very popular for
the generation of high quality quad meshes. In contrast to previous approaches,
they allow for intuitive user control in order to accommodate all kinds of application
driven constraints and design intentions. A major obstacle in practice, however,
are the relatively long computations that lead to response times of several minutes
already for input models of moderate complexity. In this paper we introduce a
novel strategy to handle highly complex input meshes with up to several millions
of triangles such that quad meshes can still be created and edited within an interactive
workflow. Our method is based on representing the input model on different levels
of resolution with a mechanism to propagate parametrizations from coarser to finer
levels. The major challenge is to guarantee consistent parametrizations even in
the presence of charts, transition functions, and singularities. Moreover, the
remaining degrees of freedom on coarser levels of resolution have to be chosen
carefully in order to still achieve low distortion parametrizations. We demonstrate
a prototypic system where the user can interactively edit quad meshes with powerful
high-level operations such as guiding constraints, singularity repositioning,
and singularity connections.

text: AbstractVarious applications of global surface
parametrization benefit from the alignment of parametrization isolines with principal
curvature directions. This is particularly true for recent parametrization‐based
meshing approaches, where this directly translates into a shape‐aware edge flow,
better approximation quality, and reduced meshing artifacts. Existing methods
to influence a parametrization based on principal curvature directions suffer
from scale‐dependence, which implies the necessity of parameter variation, or
try to capture complex directional shape features using simple 1D curves. Especially
for non‐sharp features, such as chamfers, fillets, blends, and even more for organic
variants thereof, these abstractions can be unfit. We present a novel approach
which respects and exploits the 2D nature of such directional feature regions,
detects them based on coherence and homogeneity properties, and controls the parametrization
process accordingly. This approach enables us to provide an intuitive, scale‐invariant
control parameter to the user. It also allows us to consider non‐local aspects
like the topology of a feature, enabling further improvements. We demonstrate
that, compared to previous approaches, global parametrizations of higher quality
can be generated without user intervention.

text: 'AbstractDirection fields and vector fields
play an increasingly important role in computer graphics and geometry processing.
The synthesis of directional fields on surfaces, or other spatial domains, is
a fundamental step in numerous applications, such as mesh generation, deformation,
texture mapping, and many more. The wide range of applications resulted in definitions
for many types of directional fields: from vector and tensor fields, over line
and cross fields, to frame and vector‐set fields. Depending on the application
at hand, researchers have used various notions of objectives and constraints to
synthesize such fields. These notions are defined in terms of fairness, feature
alignment, symmetry, or field topology, to mention just a few. To facilitate these
objectives, various representations, discretizations, and optimization strategies
have been developed. These choices come with varying strengths and weaknesses.
This report provides a systematic overview of directional field synthesis for
graphics applications, the challenges it poses, and the methods developed in recent
years to address these challenges.'

text: This paper presents a method for bijective parametrization of 2D and
3D objects over canonical domains. While a range of solutions for the two-dimensional
case are well-known, our method guarantees bijectivity of mappings also for a
large, combinatorially-defined class of tetrahedral meshes (shellable meshes).
The key concept in our method is the piecewise-linear (PL) foliation, decomposing
the mesh into one-dimensional submanifolds and reducing the mapping problem to
parametrization of a lower-dimensional manifold (a foliation section). The maps
resulting from these foliations are proved to be bijective and continuous, and
shown to have provably bijective PL approximations. We describe exact, numerically
robust evaluation methods and demonstrate our implementation's capabilities on
a large variety of meshes.

text: Before execution, users should formally validate the correctness of software
received from untrusted providers. To accelerate this validation, in the proof
carrying code (PCC) paradigm the provider delivers the software together with
a certificate, a formal proof of the software’s correctness. Thus, the user only
checks if the attached certificate shows correctness of the delivered software.Recently,
we introduced configurable program certification, a generic, PCC based framework
supporting various software analyses and safety properties. Evaluation of our
framework revealed that validation suffers from certificate reading. In this paper,
we present two orthogonal approaches which improve certificate validation, both
reducing the impact of certificate reading. The first approach reduces the certificate
size, storing information only if it cannot easily be recomputed. The second approach
partitions the certificate into independently checkable parts. The trick is to
read parts of the certificate while already checking read parts. Our experiments
show that validation highly benefits from our improvements.

text: In this paper, we introduce an approach for combining embedded systems with
Service-oriented Computing techniques based on a concrete application scenario
from the robotics domain. Our proposed Service-oriented Architecture allows for
incorporating computational expensive functionality as services into a distributed
computing environment. Furthermore, our framework facilitates a seamless integration
of embedded systems such as robots as service providers into the computing environment.
The entire communication is based on so-called recipes, which can be interpreted
as autonomous messages that contain all necessary information for executing compositions
of services.

text: Automated service composition aims at automatically generating software solutions
based on services to provide more complex functionality. In this paper, we give
an initial overview about why adaptivity becomes increasingly important when aiming
for automated composition of service functionality in dynamic and freely accessible
environments such as service markets. We systematically derive dependencies among
crucial processes such as service composition and service execution in a holistic
view. Furthermore, we briefly discuss the influences and effects of changes in
the environment according to the derived dependencies, and discuss possible future
research directions.

text: ervices are self-contained and platform independent software components that
aim at maximizing software reuse. The automated composition of services to a target
software artifact has been tackled with many AI techniques, but existing approaches
make unreasonably strong assumptions such as a predefined data flow, are limited
to tiny problem sizes, ignore non-functional properties, or assume offline service
repositories. This paper presents an algorithm that automatically composes services
without making such assumptions. We employ a backward search algorithm that starts
from an empty composition and prepends service calls to already discovered candidates
until a solution is found. Available services are determined during the search
process. We implemented our algorithm, performed an experimental evaluation, and
compared it to other approaches.

text: On-the-fly composition of service-based software solutions is still a challenging
task. Even more challenges emerge when facing automatic service composition in
markets of composed services for end users. In this paper, we focus on the functional
discrepancy between “what a user wants” specified in terms of a request and “what
a user gets” when executing a composed service. To meet the challenge of functional
discrepancy, we propose the combination of existing symbolic composition approaches
with machine learning techniques. We developed a learning recommendation system
that expands the capabilities of existing composition algorithms to facilitate
adaptivity and consequently reduces functional discrepancy. As a representative
of symbolic techniques, an Artificial Intelligence planning based approach produces
solutions that are correct with respect to formal specifications. Our learning
recommendation system supports the symbolic approach in decision-making. Reinforcement
Learning techniques enable the recommendation system to adjust its recommendation
strategy over time based on user ratings. We implemented the proposed functionality
in terms of a prototypical composition framework. Preliminary results from experiments
conducted in the image processing domain illustrate the benefit of combining both
complementary techniques.
