“…While in [16] we describe the migration support part of the framework, this paper focuses on support for the Broker Service that will help in choosing between HLA Services on the Grid not only during setup of the HLA-based application, but also while performing migration decisions under two different scenarios -failure or bad performance. We are currently working on the following issues: Broker Decisions and Benchmark Analyzer.…”

Abstract. The execution of High Level Architecture (HLA) distributed interactive simulations in an unreliable Grid environment requires efficient brokering of resources, which is an important part of the Grid Services framework supporting execution of such simulations. This paper presents the overall architecture of the framework with emphasis on services supplying the Broker Service with information about application performance on a Wide Area Network (WAN). For that purpose, a benchmark interaction-simulation-visualization schema is designed basing on CrossGrid medical application architecture [1,10].

Interactive Problem Solving Environments (PSEs) offer an integrated approach for constructing and running complex systems, such as distributed simulation systems. To achieve efficient execution of High Level Architecture (HLA)-based distributed interactive simulations on the Grid, we introduce a PSE called Grid HLA Management System (G-HLAM) for their management. This is done by introducing migration and monitoring mechanisms for such applications. In this paper we present how G-HLAM can be applied to the applications supporting surgeons with simulations of vascular reconstruction, using distributed federations on the Grid for the communication among simulation and visualization components.

SUMMARYBecause of the availability of shared resources, substantial efforts have been applied to the development of large‐scale distributed simulations, and performance has become an essential aspect that can be impaired by heterogeneity and availability of resources, dynamic, unpredictable load imbalances, and communication delays. In order to manage and keep such distributed simulations consistent, the high level architecture (HLA) standard has been designed; however, it does not provide any solution that directly solves simulation performance issues. Many balancing approaches have been proposed in order to offer a suboptimal balancing solution, but they are limited to certain simulation aspects, are specific to determined applications, or are unaware of the HLA‐based simulation characteristics. In light of considering both computational and communication aspects for HLA‐based simulations, a centralized hierarchical balancing scheme was proposed. This scheme presents several drawbacks that make it susceptible to bottlenecks, overheads, global synchronization, and single point of failure. Therefore, a scheme based on a distributed algorithm to re‐arrange the computational and communication load is proposed. Experiments have been performed to evaluate the effectiveness of the distributed scheme when compared with the scheme based on a centralized redistribution algorithm. The results showed that the distributed balancing technique could provide similar performance gain or even improve it for some specific cases. Copyright © 2011 John Wiley & Sons, Ltd.
