Abgrenzung bestehender Beschreibungsmittel für die Modellierung und Spezifikation von Manufacturing Execution Systems

Die Modellierung und Spezifikation von Manufacturing Execution Systems (MES) als prozessnah operierende Software-Systeme stellt eine Herausforderung interdisziplinärer Kommunikation dar. Bisher existiert kein grafisches Beschreibungsmittel, das diesen Prozess ausdrücklich unterstützt. In diesem Diskussionspapier werden bestehende Beschreibungsmittel aus angrenzenden Bereichen, wie die Business Process Modeling Notation, Petrinetze, die formalisierte Prozessbeschreibung oder die Unified Modelling Language anhand allgemeiner und MES-spezifischer Anforderungen auf ihre Eignung untersucht. Es wurden erhebliche Lücken bei der Erfüllung der Anforderungen durch bestehende Beschreibungsmittel identifiziert.

Pi: A Parallel Architecture Interface for Multi-Model Execution

This thesis defines Pi, a parallel architecture interface that separates model and machine issues, allowing them to be addressed independently. This provides greater flexibility for both the model and machine builder. Pi addresses a set of common parallel model requirements including low latency communication, fast task switching, low cost synchronization, efficient storage management, the ability to exploit locality, and efficient support for sequential code. Since Pi provides generic parallel operations, it can efficiently support many parallel programming models including hybrids of existing models. Pi also forms a basis of comparison for architectural components.

Grid Remote Execution (G-Rex) of Climate Models

G-Rex is light-weight Java middleware that allows scientific applications deployed on remote computer systems to be launched and controlled as if they are running on the user's own computer. G-Rex is particularly suited to ocean and climate modelling applications because output from the model is transferred back to the user while the run is in progress, which prevents the accumulation of large amounts of data on the remote cluster. The G-Rex server is a RESTful Web application that runs inside a servlet container on the remote system, and the client component is a Java command line program that can easily be incorporated into existing scientific work-flow scripts. The NEMO and POLCOMS ocean models have been deployed as G-Rex services in the NERC Cluster Grid, and G-Rex is the core grid middleware in the GCEP and GCOMS e-science projects.

Autonomous execution of tasks by swarm carrier agents in swarm-array computing

How can a bridge be built between autonomic computing approaches and parallel computing system? The work reported in this paper is motivated towards bridging this gap by proposing swarm-array computing, a novel technique to achieve autonomy for distributed parallel computing systems. Among three proposed approaches, the second approach, namely 'Intelligent Agents' is of focus in this paper. The task to be executed on parallel computing cores is considered as a swarm of autonomous agents. A task is carried to a computing core by carrier. agents and can be seamlessly transferred between cores in the event of a pre-dicted failure, thereby achieving self-ware objectives of autonomic computing. The feasibility of the proposed approach is validated on a multi-agent simulator.
