ABSTRACT -- During the past decade, tremendous amounts of computing resources has been invested. The computing resources include not only hardware and software but also data communication infrastructure. Human society, as a whole, has better understanding and accustom to the benefit of information technologies. These factors drive the needs in higher degree of resource sharing. The Grid enable technologies will allow efficient computing resource sharing and collaboration among different entities. The computing resource sharing is needed to be improved significantly in terms of application domains, user interactions, security, and resource management. Deploying grid enable technologies is not a trivial task. In this paper, we present the hardware-software architecture deployed in the ThaiGrid. The ThaiGrid is the collaborative project intended to create a high performance computing testbed in Thailand. The Kasetsart University and the King Mongkut's Institute of Technology are the two universities involve in the initial implementation of the ThaiGrid. The ThaiGrid consists of three high performance computing platforms. An overview of the Grid middle-ware implemented on the ThaiGrid is presented.
