Presented is a graphical interface for managing at least reservations and jobs within a compute environment such as a cluster or a grid. A user can graphically view reservations and jobs in the environment and interact with the interface to modify and create reservations with a view of the current status of the resources, available resources and graphically see how proposed changes, additions or modifications of reservations would affect the environment. The invention may comprise a graphical user interface, a computing device for operating the graphical user interface, a computer-readable medium storing instructions for controlling a computing device to utilize the run the graphical interface, and methods of interacting with the user through the graphical user interface. Disclosed are various graphical windows that present in different ways past resource consumption, a current time and future resource predicted usage based on at least one of jobs running and reservations. The interface also includes a window that shows user credentials and dependencies between users, administrators and policies.
