TeraGrid is a national-scale computational science facility supported through a partnership among thirteen institutions, with funding from the US National Science Foundation . Initially created through a Major Research Equipment Facilities Construction (MREFC ) award in 2001, the TeraGrid facility began providing production computing, storage,… (More)
An important type of communication in grid and distributed computing environments is bulk data transfer. GridFTP has emerged as a de facto standard for secure, reliable, high-performance data transfer across resources on the grid. GridCopy provides a simple GridFTP client interface to users and extensible configuration that can be changed dynamically by… (More)
OBJECTIVE As biomedical technology becomes increasingly sophisticated, researchers can probe ever more subtle effects with the added requirement that the investigation of small effects often requires the acquisition of large amounts of data. In biomedicine, these data are often acquired at, and later shared between, multiple sites. There are both… (More)
SUMMARY Many production Grid and e-Science infrastructures have begun to offer services to end-users during the past several years with an increasing number of scientific applications that require access to a wide variety of resources and services in multiple Grids. Therefore, the Grid Interoperation Now—Community Group of the Open Grid Forum—organizes and… (More)

This paper is intended to explain how the Tera Grid would like to be able to measure "usage modalities." We would like to (and are beginning to) measure these modalities to understand what objectives our users are pursuing, how they go about achieving them, and why, so that we can make changes in the Tera Grid to better support them.
Systems administrators of large clusters often need to perform the same administrative activity hundreds or thousands of times. Often such activities are time-consuming, especially the tasks of installing and maintaining software. By combining network services such as DHCP, TFTP, FTP, HTTP, and NFS with remote hardware control, cluster administrators can… (More)
In this paper, we describe the use of a cluster as a generalized facility for development. A development facility is a system used primarily for testing and development activities while being operated reliably for many users. We are in the midst of a project to build and operate a large-scale development facility. We discuss our motivation for using… (More)
Visualization is an important part of the data analysis process. Many researchers, however, do not have access to the resources required to do visualization effectively for large datasets. This problem is illustrated through several user scenarios. To remedy this problem, we propose a Visualization Gateway that provides simplified access to such resources… (More)
While configuration management systems are generally regarded as useful, their deployment process is not well understood or documented. In this paper, we present a case study in configuration management tool deployment. We describe the motivating factors and both the technical considerations and the social issues involved in this process. Our discussion… (More)
