The present invention relates to a composite material including a substrate with a first and a second surface, a boundary layer which is comprised of one or more compositions, and a topical application. According to various embodiments of the invention, power usage of an HPC cluster is reduced by boosting the performance of one or more select nodes within the cluster so that the one or more nodes take less time to complete. The threshold position may be fixed and a pedal mapping curve fit to pass through the threshold position.
