A method in a computer system for coordinating scheduling of threads among a plurality of processors. A plurality of apertures through the vent strip enabling air circulation. The energy at the input is derived from an AC mains voltage at a mains frequency. Disabling a supply of power to a traction motor may be based on current operating conditions, such as speed. Various other methods, systems, and computer-readable media are also disclosed. The invention further provides for the IO processor to refresh the cache memory after receipt of alteration of the IO force data from the processor.
