“…The system can run in the internet or LAN (Local Area Network) condition. According to the system requirements and basic idea, an implementation scheme for collaborative virtual assembly based on HLA/RTI protocol (IEEE Standard 2000; Ounnar et al 2009) and MPI (Message Passing Interface) (Le and Rejeb 2006; http://www.mpi-forum.org) shown in Fig. 2, has been proposed.…”

As complex products such as automobiles and ships are usually developed at geographically dispersed locations, it brings the difficulty for component model verification and assembly process evaluation. To cope with this challenge, a relatively comprehensive system scheme which supports complex product real-time collaborative interactive assembly is proposed. To get high performance, the technologies such as parallel rendering for complex scene based on pc-cluster, high-efficient collision detection method, the mechanism of event synchronization based on HLA/RTI (High level Architecture/Run-time Infrastructure) are applied. A prototype system named Distributed Parallel Virtual Assembly Environment (DPVAE) is developed. With DPVAE, users at different location can do assembly operation collaboratively by hand or by tool, to conduct the component model verification and assembly process evaluation at the same time. Through a case study of RA750 car assembly, the validity of system functions has been demonstrated successfully.

“…The total time, t n , used by a parallel program running on n server processors is composed of the time associated to the communication costs plus the time corresponding to the execution of the code. The different factors affecting performance in currently distributed systems have been included by Le and Rejeb [32] in a modified LogGP performance model. Using this model, t n can be expressed as…”

“…Both, L and G can be considered independent of the number of processors, n. The term h is the function introduced by Le and Rejeb [32] to describe the overhead cost associated with the use of middleware in the parallelization process in the master (h m ) and server (h s ). Finally, t Seq and t p represent the time used by the sequential and parallelizable parts of the code, respectively.…”

“…LoPC and LoGPC are extensions to active messages [28,29], and LoGPS accounts for synchronization costs [30]. Performance models tailored for distributed systems have also been proposed [31][32][33]. Also, an empirical study has been presented recently on the performance behavior of Grid connected clusters using the NPB set of applications [34].…”

SUMMARYThis work focuses on the use of computational Grids for processing the large set of jobs arising in parameter sweep applications. In particular, we tackle the mapping of molecular potential energy hypersurfaces. For computationally intensive parameter sweep problems, performance models are developed to compare the parallel computation in a multiprocessor system with the computation on an Internet-based Grid of computers. We find that the relative performance of the Grid approach increases with the number of processors, being independent of the number of jobs. The experimental data, obtained using electronic structure calculations, fit the proposed performance expressions accurately. To automate the mapping of potential energy hypersurfaces, an application based on GRID superscalar is developed. It is tested on the prototypical case of the internal dynamics of acetone.

“…Considerando o FPGA com unidades de processamento mais básicas e com baixo custo para a troca de informação entre processos, ao contrário de uma arquitetura em rede, na qual os processos podem ser bastante complexos, porém possuem grande custo de comunicação (Le & Rejeb, 2006). AEs paralelos são classificados de acordo com a divisão das subpopulações, pela forma com que elas interagem e como são feitas as migrações entre diferentes instâncias do problema.…”
