16 * The launch data structure resides at a fixed place in each node's memory

18 * processors.

20 * The master stores launch parameters in the launch structure
21 * corresponding to a target processor that is in a slave loop, then sends
22 * an interrupt to the slave processor. The slave calls the desired
23 * function, then returns to the slave loop. The master may poll or wait
24 * for the slaves to finish.
25 *
26 * There is an array of launch structures, one per CPU on the node. One
27 * interrupt level is used per local CPU.
