/**

 * mnParTrainDa.c
 *
 * Feature which performs Memory DQS training on each node with each node training
 * its own memory through code running on a core in the associated processor.
 * This way memory can be trained in parallel by more than one processor.
 *
 * This file contains the Deerhound specific parallel training function.
