TL;DR: This paper presents a description of the language in its current form, along with requirements that led up to it, and studies notations for users to express reconfiguration plans.
Abstract: In order to help programmers achieve greater leverage of emerging reconfiguration mechanisms, we are studying notations for users to express reconfiguration plans. These plans direct how a running distributed application would be changed, based upon recognition of events from either the application itself or its environment. Our work to date in this area is embodied in a simple system called Clipper. Based upon C++, Clipper provides a way for programmers to express plans, that are then used to automatically generate the run time mechanisms needed to validly reflect the programmer's rules for change in the application. This paper presents a description of our language in its current form, along with requirements that led up to it. >

TL;DR: An architecture of reconfigurable multiagent systems is defined, where a reconfiguration agent modeled by nested state machines is affected to each device of the execution environment to apply local automatic reconfigurations, and a coordination agent is proposed for any coordination between devices in order to guarantee safe and adequate distributed reconfigurements.
Abstract: This paper deals with distributed multiagent reconfigurable embedded-control systems following the component-based International Industrial Standard IEC61499 in which a function block (FB) is an event-triggered software component owning data and a control application is a distributed network of FBs. We define an architecture of reconfigurable multiagent systems, where a reconfiguration agent modeled by nested state machines is affected to each device of the execution environment to apply local automatic reconfigurations, and a coordination agent is proposed for any coordination between devices in order to guarantee safe and adequate distributed reconfigurations. A communication protocol is proposed in our research to handle coordinations between agents by using well-defined coordination matrices. We define, in addition, Extensible Markup Language (XML) based implementations for both kinds of agents, where XML code blocks are exchanged between devices. The contributions of the paper are applied to two benchmark production systems available in our laboratory.

TL;DR: This work has implemented malleability as an extension to the PCM (process checkpointing and migration) library, a user-level library for iterative MPI applications, a framework for middleware-driven dynamic application reconfiguration.
Abstract: Malleability enables a parallel application's execution system to split or merge processes modifying granularity. While process migration is widely used to adapt applications to dynamic execution environments, it is limited by the granularity of the application's processes. Malleability empowers process migration by allowing the application's processes to expand or shrink following the availability of resources. We have implemented malleability as an extension to the PCM (process checkpointing and migration) library, a user-level library for iterative MPI applications. PCM is integrated with the Internet operating system (IOS), a framework for middleware-driven dynamic application reconfiguration. Our approach requires minimal code modifications and enables transparent middleware- triggered reconfiguration. Experimental results using a two-dimensional data parallel program that has a regular communication structure demonstrate the usefulness of malleability.

TL;DR: The framework provides definitions that allow modeling of applications and execution semantics separately and can be used to analyze and compare how an application would behave when executed using different execution semantics.
Abstract: IEC 61499 is a standard architecture, based on function blocks, for developing distributed control and measurement applications. However, the standard has no formal semantics and different interpretations of the standard have emerged. As a consequence, it is harder to transfer applications between different standard compliant platforms. This paper presents a formal framework for mathematical modeling and comparison of different execution semantics. The framework provides definitions that allow modeling of applications and execution semantics separately. Together, the models can be used to analyze and compare how an application would behave when executed using different execution semantics. In addition, a mathematical model made possible by the framework has been used as a basis for implementation of a runtime environment that can execute applications and a software tool that generates formal models suitable for formal verification, both assuming different execution semantics.

TL;DR: A novel methodology for processor evaluation in an embedded systems design environment that includes identification of application parameters which can influence processor selection, a mechanism to capture widely varying processor architectures and an instruction constrained scheduler is presented.
Abstract: In this paper we present a novel methodology for processor evaluation in an embedded systems design environment. This evaluation can help in either selecting a suitable processor core or in evaluating changes to an ASIP. The processor evaluation is carried out in two stages. First, an architecture independent stage in which processors are rejected based on key application parameters and secondary architecture dependent stage in which performance is estimated on selected processors. The contribution of our work includes identification of application parameters which can influence processor selection, a mechanism to capture widely varying processor architectures and an instruction constrained scheduler. Initial experimental results suggest the potential of this approach.
