A modular memory optimization for synchronous data-flow languages.
In <em>Proc. of the ACM International Conference on Languages,
Compilers, Tools and Theory for Embedded Systems (LCTES'12)</em>, Beijing, China,
June 2012.
[&nbsp;<a href="publications_bib.html#Gerard:2012">bib</a>&nbsp;]
<blockquote><font size="-1">
The generation of efficient sequential code for
synchronous data-flow languages raises two
intertwined issues: control and memory
optimization. While the former has been extensively
studied, for instance in the compilation of LUSTRE
and SIGNAL, the latter has only been addressed in a
restricted manner. Yet, memory optimization becomes
a pressing issue when arrays are added to such
languages. This article presents a two-level
solution to the memory optimization problem. It
combines a compile-time optimization algorithm,
reminiscent of register allocation, paired with
language annotations on the source given by the
designer. Annotations express in-place modifications
and control where allocation is performed. Moreover,
they allow external functions performing in-place
modifications to be safely imported. Soundness of
annotations is guaranteed by a semilinear type
system and additional scheduling constraints. A key
feature is that annotations for well-typed programs
do not change the semantics of the language:
removing them may lead to less efficient code but
will not alter the semantics. The method has been
implemented in a new compiler for a LUSTRE-like
synchronous language extended with hierarchical
automata and arrays. Experiments show that the
proposed approach removes most of the unnecessary
array copies, resulting in faster code that uses
less memory.

Automatic generation of discrete handlers of real-time continuous

In <em>Proc. 18th World Congress of the International Federation of

<blockquote><font size="-1">
We present a novel technique for designing discrete,
logical control loops, on top of continuous control
tasks, ensuring logical safety properties of the
tasks sequencings and mode changes. We define this
new handler on top of the real-time executives built
with the Orccad design environment for control
systems, which is applied, e.g. to robotics and
real-time networked control. It features structures
of control tasks, each equipped with a local
automaton, used for the reactive, event-based
management of its activity and modes. The
additional discrete handler manages the interactions
between tasks, concerning, e.g., mutual exclusions,
forbidden or imposed sequences. We use a new
reactive programming language, with constructs for
finite-state machines and data-flow nodes, and a
mechanism of behavioral contracts, which involves
discrete controller synthesis. The result is a
discrete control loop, on top of the continuous
control loops, all integrated in a coherent
real-time architecture. Our approach is illustrated
and validated experimentally with the case study of
a robot arm.

Synchronous control of reconfiguration in fractal component-based

<blockquote><font size="-1">
In the context of component-based embedded systems,
the management of dynamic reconfiguration in
adaptive systems is an increasingly important
feature. The Fractal component-based framework, and
its industrial instantiation MIND, provide for
support for control operations in the lifecycle of
components. Nevertheless, the use of complex and
integrated architectures make the management of this
reconfiguration operations difficult to handle by
programmers. To address this issue, we propose to
use Synchronous languages, which are a complete
approach to the design of reactive systems, based on
behavior models in the form of transition
systems. Furthermore, the design of closed-loop
reactive managers of reconfigurations can benefit
from formal tools like Discrete Controller
Synthesis. In this paper we describe an approach to
concretely integrate synchronous reconfiguration
managers in Fractal component-based systems. We
describe how to model the state space of the control
problem, and how to specify the control
objectives. We describe the implementation of the
resulting manager with the Fractal/Cecilia
programming environment, taking advantage of the
Comete distributed middleware. We illustrate and
validate it with the case study of the Comanche HTTP
server on a multi-core execution platform.

Green computing is nowadays a major challenge for

promising approach to control the QoS and the energy

investigates the use of synchronous programming and
discrete controller synthesis to automate the
generation of a controller that enforces the
required coordination between QoS and energy

<blockquote><font size="-1">
We describe the extension of a reactive programming
language with a behavioral contract construct. It
is dedicated to the programming of reactive control
of applications in embedded systems, and involves
principles of the supervisory control of discrete
event systems. Our contribution is in a language
approach where modular discrete controller synthesis
(DCS) is integrated, and it is concretized in the
encapsulation of DCS into a compilation process.
From transition system specifications of possible
behaviors, DCS automatically produces controllers
that make the controlled system satisfy the property
given as objective. Our language features and
compiling technique provide
correctness-by-construction in that sense, and
enhance reliability and verifiability. Our
application domain is adaptive and reconfigurable
systems: closed-loop adaptation mechanisms enable
flexible execution of functionalities w.r.t.
changing resource and environment conditions. Our
language can serve programming such adaption
controllers. This paper particularly describes the
compilation of the language. We present a method
for the modular application of discrete controller
synthesis on synchronous programs, and its
integration in the BZR language. We consider
structured programs, as a composition of nodes, and
first apply DCS on particular nodes of the program,
in order to reduce the complexity of the controller
computation; then, we allow the abstraction of parts
of the program for this computation; and finally, we
show how to recompose the different controllers
computed from different abstractions for their
correct co-execution with the initial program. Our
work is illustrated with examples, and we present
quantitative results about its implementation.

abstract = {The generation of efficient sequential code for
synchronous data-flow languages raises two
intertwined issues: control and memory
optimization. While the former has been extensively
studied, for instance in the compilation of LUSTRE
and SIGNAL, the latter has only been addressed in a
restricted manner. Yet, memory optimization becomes
a pressing issue when arrays are added to such
languages. This article presents a two-level
solution to the memory optimization problem. It
combines a compile-time optimization algorithm,
reminiscent of register allocation, paired with
language annotations on the source given by the
designer. Annotations express in-place modifications
and control where allocation is performed. Moreover,
they allow external functions performing in-place
modifications to be safely imported. Soundness of
annotations is guaranteed by a semilinear type
system and additional scheduling constraints. A key
feature is that annotations for well-typed programs
do not change the semantics of the language:
removing them may lead to less efficient code but
will not alter the semantics. The method has been
implemented in a new compiler for a LUSTRE-like
synchronous language extended with hierarchical
automata and arrays. Experiments show that the
proposed approach removes most of the unnecessary
array copies, resulting in faster code that uses
less memory. }

abstract = {{In the context of component-based embedded systems,
the management of dynamic reconfiguration in
adaptive systems is an increasingly important
feature. The Fractal component-based framework, and
its industrial instantiation MIND, provide for
support for control operations in the lifecycle of
components. Nevertheless, the use of complex and
integrated architectures make the management of this
reconfiguration operations difficult to handle by
programmers. To address this issue, we propose to
use Synchronous languages, which are a complete
approach to the design of reactive systems, based on
behavior models in the form of transition
systems. Furthermore, the design of closed-loop
reactive managers of reconfigurations can benefit
from formal tools like Discrete Controller
Synthesis. In this paper we describe an approach to
concretely integrate synchronous reconfiguration
managers in Fractal component-based systems. We
describe how to model the state space of the control
problem, and how to specify the control
objectives. We describe the implementation of the
resulting manager with the Fractal/Cecilia
programming environment, taking advantage of the
Comete distributed middleware. We illustrate and
validate it with the case study of the Comanche HTTP
server on a multi-core execution platform.}},

abstract = {We present a technique for designing reconfiguration
controllers in the Fractal component-based
framework. We obtain discrete control loops that
automatically enforce safety properties on the
interactions between components, concerning, e.g.,
mutual exclusions, forbidden or imposed sequences.
We use a reactive programming language, with a new
mechanism of behavioural contracts. Its compilation
involves discrete controller synthesis, which
automatically generates the correct adaptation
controllers. We apply our approach to the problem
of adaptive ressource management, illustrated by the
example of a HTTP server.},

abstract = {Green computing is nowadays a major challenge for
most IT organizations. Administrators have to
manage the trade-off between system performances and
energy saving goals. Autonomic computing is a
promising approach to control the QoS and the energy
consumed by a system. This paper precisely
investigates the use of synchronous programming and
discrete controller synthesis to automate the
generation of a controller that enforces the
required coordination between QoS and energy
managers. We illustrate our approach by describing
the coordination between a simple admission
controller and an energy controller.},

month = aug,
year = 2011,
abstract = {We present a novel technique for designing discrete,
logical control loops, on top of continuous control
tasks, ensuring logical safety properties of the
tasks sequencings and mode changes. We define this
new handler on top of the real-time executives built
with the Orccad design environment for control
systems, which is applied, e.g. to robotics and
real-time networked control. It features structures
of control tasks, each equipped with a local
automaton, used for the reactive, event-based
management of its activity and modes. The
additional discrete handler manages the interactions
between tasks, concerning, e.g., mutual exclusions,
forbidden or imposed sequences. We use a new
reactive programming language, with constructs for
finite-state machines and data-flow nodes, and a
mechanism of behavioral contracts, which involves
discrete controller synthesis. The result is a
discrete control loop, on top of the continuous
control loops, all integrated in a coherent
real-time architecture. Our approach is illustrated
and validated experimentally with the case study of
a robot arm. },

Component-based Systems -- a Case Study},
author = {Bouhadiba, Tayeb and Sabah, Quentin and Delaval,
Gwena{\"e}l and Rutten, \'Eric},
abstract = {{In the context of component-based embedded systems,
the management of dynamic reconfiguration in
adaptive systems is an increasingly important
feature. The Fractal component-based framework, and
its industrial instantiation MIND, provide for
support for control operations in the lifecycle of
components. Nevertheless, the use of complex and
integrated architectures make the management of this
reconfiguration operations difficult to handle by
programmers. To address this issue, we propose to
use Synchronous languages, which are a complete
approach to the design of reactive systems, based on
behavior models in the form of transition
systems. Furthermore, the design of closed-loop
reactive managers of reconfigurations can benefit
from formal tools like Discrete Controller
Synthesis. In this paper we describe an approach to
concretely integrate synchronous reconfiguration
managers in Fractal component-based systems. We
describe how to model the state space of the control
problem, and how to specify the control
objectives. We describe the implementation of the
resulting manager with the Fractal/Cecilia
programming environment, taking advantage of the
Comete distributed middleware. We illustrate and
validate it with the case study of the Comanche HTTP
server on a multi-core execution platform.}},
