Abstract
Many High Performance Computing applications have a static load balance which is easy and cheap to implement. When one or a few nodes are not performing properly this makes the whole code slow down to the rate limiting performance of the slowest node. We describe the utilization of a coded called Bugget which has been used on Catamount and the Cray Linux Environment to quickly identify these nodes so they can be removed from the user pool until the next appropriate maintenance period.
