This paper elaborates on mechanisms by which users, data, and applications can bedecoupledfrom individual computers and administrative domains. The mechanisms, which consist of logical user accounts and a virtual #le system, introduce a layer of abstraction between the physical computing infrastructure and the virtual computational grid perceived by users. This abstraction converts compute servers into interchangeable parts, allowing a computational grid to assemble computing systems at run time without being limited by the traditional constraints associated with user accounts, #le systems, and administrative domains. The described approach has already been deployedinthe
