This paper exposes the implementation of a service oriented platform that performs an on demand 3D static and dynamic structural analysis of highrise buildings using a Grid Computing infrastructure. The Grid Service has been developed over the middleware Globus Toolkit 4, offering to the structural scientific community an on-line multi-user service. The requirements of high throughput and robustness needed, by such a system, have forced to integrate a highly reliable Grid meta-scheduler that enables to share appropriately the computational resources. The developed system offers a multilevel fault tolerance that guarantees that every simulation request received in the Grid Service will be satisfactorily attended. Another important aspect that has been taken into account has been the security, offering user authorization and authentication, and data privacy and integrity mechanisms, critical issues in a system available in the network. In addition, an advanced GUI client that interacts with the Grid Service has also been implemented, assisting the client in the pre-process and post-processing stages, and in the structural analysis parameter definition. |
