title = "Using a computational grid for geographic information analysis: A reconnaissance",
abstract = "High performance computing has undergone a radical transformation during the past decade. Though monolithic supercomputers continue to be built with significantly increased computing power, geographically distributed computing resources are now routinely linked using high-speed networks to address a broad range of computationally complex problems. These confederated resources are referred to collectively as a computational Grid. Many geographical problems exhibit characteristics that make them candidates for this new model of computing. As an illustration, we describe a spatial statistics problem and demonstrate how it can be addressed using Grid computing strategies. A key element of this application is the development of middleware that handles domain decomposition and coordinates computational functions. We also discuss the development of Grid portals that are designed to help researchers and decision makers access and use geographic information analysis tools.",

note = "Funding Information: The Globus Toolkit, a part of the National Science Foundation Middleware Initiative (http:// www.nsf-middleware.org), is becoming a de facto standard of Grid middleware. Globus adopts the {\textquoteleft}{\textquoteleft}hourglass model{\textquoteright}{\textquoteright} (National Research Council 1994) to construct interfaces between different layers of Grid middleware components (Foster, Kesselman, and Tuecke 2001) (Figure 1). The {\textquoteleft}{\textquoteleft}hourglass neck{\textquoteright}{\textquoteright} consists of the resource and connectivity layers shown in Figure 1. In these two layers, the Globus Toolkit integrates the following four protocols: Funding Information: The development of domain-specific PSEs is regarded as an important focus of Grid computing research and development activity. For example, supported by the National Science Foundation Middleware Initiative, the OGCE (Open Grid Computing Environments) project was established in 2003 to foster collaborations and promote the development of sharable and reusable components within the Grid portal development community (Gannon et al. 2004). The OGCE focuses on establishing a repository of portal service components that can be used to develop domain-specific PSEs.",
