This paper addressed extending quality data in lot-based traceability information system through modeling and evaluation which is purposely designed for small-to-medium size enterprise (SMEs). The solution translates the system behavior and value data arisen from traceability requirement into useful and organized computerized information system. Easy-understanding and economic approach in design and implementation meets conditions of SME environment. The designed information system through data query evaluates the functionality of quality data dynamically.

In this paper we simulate the use of two string based parallel robots in cooperative manipulation task. Two users standing in front of a large screen operate each robot. We propose two haptic guide models, and investigate their effects on cooperation, co-presence and users performance. In addition we also examine the effect of object-based force feedback in cooperative work. Ten volunteer subjects had to cooperatively perform a peg-in-hole task. Results revealed that haptic guides have a significant effect on task execution. They not only increase users performance but also enhance the sense of co-presence and awareness. Our investigations will help in the development of VR systems for cooperative assembly, surgical training and rehabilitation.

Multicore systems have become standard for desktop computers today. Current operating systems and software development tools provide straightforward means to use the additional computing power. However, a more fundamental change in the design and development of software is required to fully exploit the power of multicore systems. Furthermore, the fast growing market of embedded systems is currently largely unaffected by the introduction of multicore systems. This will change quickly in the future, which will mean that there will be a demand on efficient development of reliable embedded software that can give real-time guarantees and exploit the available power on multicore systems. The JEOPARD project addresses this demand by developing Java software tools to exploit multicore power while ensuring correctness and predictable timing. This paper gives an overview of the JEOPARD project and focuses on key technical issues such as real-time scheduling and real-time garbage collection on multi-core systems.

IEEE TRANSACTIONS ON parallel AND DISTRIBUTED SYSTEMS 2009年第11期20卷 1567-1585页

This paper presents a new algorithm for a reconfigurable distributed domain-oriented atomic object service, called DO-RAMBO, which stands for Domain-oriented Reconfigurable Atomic Memory for Basic objects. This service is suitable for inclusion as a middleware system service for distributed applications requiring atomic read/write data. The implementation substantially extends and refines the abstract RAMBO algorithm of Lynch and Shvartsman that supports individual atomic objects. In this paper, domains are introduced to allow the users to group related atomic objects. The new implementation manages configurations on the basis of domains, significantly improving the utility and the performance of the resulting service. DO-RAMBO guarantees consistency under asynchrony, message loss, node crashes, new node arrivals, and node departures. We present the formal algorithm development for DO-RAMBO and give analytical and empirical results that illustrate the benefit of the new approach.

Federated computing environments offer requestors the ability to dynamically invoke services offered by collaborating providers in the virtual service network Without an efficient resource management, however, the assignment of providers to customer's requests cannot be optimized and cannot offer high reliability without relevant SLA guarantees. We propose a new SLA-based SERViceable Metacomputing environment (SERVME) capable of matching providers based on QoS requirements and performing autonomic provisioning and deprovisioning of services according to dynamic requestor needs. This paper presents the new autonomic SLA management and the object-oriented SLA model for large-scale service-oriented systems. An initial reference implementation in the SORCER environment is also described.

Up to now, It still remains a big challenge for us to build a high performance geo-computing system with high processing speed and also be easy of use by domain researchers. The unprecedented scale data and various complex algorithms pose many computational and management challenges To properly settle these main issues above, a new system framework for high performance gco-computing is presented in this paper A High Performance Geo-data object Storage System (HPGOSS) base on parallel file System is used for eliminating I/O performance bottleneck and deal with the data managing problem result from the close relevancy between geo-information and remote sensing image data. parallel programming models for fast parallelization of geo-computing algorithms are proposed. In addition, the job scheduling strategy and workflow engine are also discussed. Finally, such system could provide a parallel geo-computing environment with high performance, easy to use, optimal resource utilization, and high scalability.

The paper describe a detailed study into the object-oriented design and implementation of distributed and parallel computing environment for Finite element analysis of parallel manipulator on desktop computers cluster using message passing while communication are needed among related computing nodes. The solution routines were blind to whether the objects were local or remote. Numerical tests were carried out and reasonable speed-up was achieved, particularly for direction solution methods. It is concluded that message passing provides a viable mechanism for computing nodes coordination while implementing distributed parallel computing environment based on personal computer(PC) cluster. ©2009 IEEE.

The pipeline structure is intuitive design pattern for parallel and distributed programming. However it has some limitations so that it can not be applied effectively, especially in the distributed environment. This paper describes a distributed pipeline programming framework (DPPF) for state-based pattern. DPPF makes use of the slate-based pipeline design pattern and object-oriented technology to design pipeline. In DPPF the pipeline stage is regard as an object that be passed between two compute nodes with its state. Message-passing method is replaced object-passing method through Java socket for information transmission. For the state pattern, all compute nodes are separated from the pipeline control flow Information transmission that runs in the background is transparent for the programmer So programmers are more easily to design pipeline structure for distributed programming. In addition, it is effective to improve the performance and dynamic load balance for some coarse-grained applications.

The use of parallel technologies to solve complex scientific problems has gained increased popularity. The ray optical methods are deterministic propagation approaches that are based on geometrically searching paths between emitter and receivers. They offer higher accuracy than empirical models, but suffer from slow calculations on exhausted rays that have to be searched. In this paper, an object-oriented scheme based on POP-C++ for parallel objects to accelerate outdoor ray launching is described. Performance evaluation is presented to show that this parallel scheme s promising in outdoor wireless propagation modeling. The possibility of running this model in the distributed grid environment is also discussed. Results have shown the great potential of using such a parallel model to predict accurate outdoor wireless propagation scenarios within a short time. © 2009 IEEE.
