Support for Effective and Fault Tolerant Execution of HLA-Based Applications in the OGSA Framework

摘要

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.
