A method and apparatus for improving multi-processor performance where the various processors are competing for spinlock acquisition is described. Hydrogen is stored on-board a motorized vehicle, or the like, in a stabilized slurry of alkali metal borohydride particles and water. The control gate may be electrically coupled with one or more of the thyristors and may be operably coupled to a voltage source. The apparatus may be used to coat an airfoil cluster of a gas turbine engine.
