It Takes More than Technology
The technology required to develop and manage a production metacenter or grid environment is an important ingredient in such a project. However, this technology may neither be the most difficult piece of the puzzle nor the one demanding the most patience and perseverance. This paper touches on the technical underpinnings of the collaborative effort that resulted in a production metacenter joining two cooperating IBM SPs, one at NASA Ames Research Center (ARC) and the other at NASA Langley Research Center (LaRC). The discussion then focuses on the problems attributable to differing environments, both physical and cultural, even though both sites were part of the same agency. The approach for the Phase I NASA Metacenter was centralized with most decisions made by the NAS Division at Ames. Also discussed is the distributed approach to resolving the even greater difficulties encountered in the multi-agency effort to modify NASA's technology to build a similar metacenter in the Department of Defense. The DoD Metacenter joins two DoD Major Shared Resource Centers (MSRCs), the Aeronautical Systems Center (ASC) MSRC at Wright-Patterson Air Force Base and the U.S. Army Engineer Research and Development Center (ERDC) MSRC. The final discussion focuses on similar problems that have arisen at NASA with the NASA Information Power Grid.
