Foregrounding the Cyberinfrastructure Center as Cyberinfrastructure Steward

A recent uptick in studies of cyberinfrastructure-enabled research projects has advanced our limited understanding of the use, development and management of cyberinfrastructure (CI) resources. Conspicuously absent from most of these studies, though, is any consideration of the key roles played by supercomputer centers, or what we term „CI centers‟, in CI-enabled research networks. This position...

A prototype ...
