text: In this chapter, we present an introduction to the ReconOS operating system
for reconfigurable computing. ReconOS offers a unified multi-threaded programming
model and operating system services for threads executing in software and threads
mapped to reconfigurable hardware. By supporting standard POSIX operating system
functions for both software and hardware threads, ReconOS particularly caters
to developers with a software background, because developers can use well-known
mechanisms such as semaphores, mutexes, condition variables, and message queues
for developing hybrid applications with threads running on the CPU and FPGA concurrently.
Through the semantic integration of 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
between different reconfigurable computing systems.

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: 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, these temperature simulations
require a high computational effort if a detailed thermal model is used and their
accuracies are often unclear. In contrast to simulations, the use of synthetic
heat sources allows for experimental evaluation of temperature management methods.
In this paper we investigate the creation of significant rises in temperature
on modern FPGAs to enable future evaluation of thermal management techniques based
on experiments. To that end, we have developed seven different heat-generating
cores that use different subsets of FPGA resources. Our experimental results show
that, according to external temperature probes connected to the FPGA’s heat sink,
we can increase the temperature by an average of 81 !C. This corresponds to an
average increase of 156.3 !C as measured by the built-in thermal diodes of our
Virtex-5 FPGAs in less than 30 min by only utilizing about 21 percent of the slices.

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: 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: 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

text: In the next decades, hybrid multi-cores will be the predominant architecture
for reconfigurable FPGA-based systems. Temperature-aware thread mapping strategies
are key for providing dependability in such systems. These strategies rely on
measuring the temperature distribution and redicting the thermal behavior of the
system when there are changes to the hardware and software running on the FPGA.
While there are a number of tools that use thermal models to predict temperature
distributions at design time, these tools lack the flexibility to autonomously
adjust to changing FPGA configurations. To address this problem we propose a temperature-aware
system that empowers FPGA-based reconfigurable multi-cores to autonomously predict
the on-chip temperature distribution for pro-active thread remapping. Our system
obtains temperature measurements through a self-calibrating grid of sensors and
uses area constrained heat-generating circuits in order to generate spatial and
temporal temperature gradients. The generated temperature variations are then
used to learn the free parameters of the system's thermal model. The system thus
acquires an understanding of its own thermal characteristics. We implemented an
FPGA system containing a net of 144 temperature sensors on a Xilinx Virtex-6 LX240T
FPGA that is aware of its thermal model. Finally, we show that the temperature
predictions vary less than 0.72 degree C on average compared to the measured temperature
distributions at run-time.
