/**

 *
 * @ingroup ScoreScheduler
 *
 * This is an implementation of the global fixed priority scheduler (G-FP).  It
 * uses one ready chain per priority to ensure constant time insert operations.
 * The scheduled chain uses linear insert operations and has at most processor
 * count entries.  Since the processor and priority count are constants all
 * scheduler operations complete in a bounded execution time.
 *
 * The thread preempt mode will be ignored.
