Implementation of a Computation Grid Platform for the Earthquake Disaster Alleviation Grid Testbed in China

In order to study the key technologies involved in setting up an earthquake disaster alleviation grid testbed in China, a programming model based on OGSA and GT3 is presented. Relationship between the grid Web application layer, the grid Web server layer and the grid resources and services layer are analyzed. Key components in the model are implemented and the security schema based on GSI is presented. Finally, the computation grid platform is constructed and the earthquake stress triggering computation for the Yunnan region is implemented on the platform. The computation result showed that the platform filled the demands of grid computation and improved computation efficiency.
