In some supercomputing environments, users are required to run editing, compiling and data-cleaning tasks on a workstation, and use supercomputers only for jobs that require them. This restriction is intended to improve the performance of the supercomputer, but it causes significant inconvenience for users. In this paper, we examine the workload submitted to the Cray C90 at the San Diego Supercomputer Center, and observe that "workstation jobs" consume less than 20% of the cycles on these machines. We conclude that the cost of supporting these jobs is small compared to the productivity improvement it provides for users.
