16 | * The launch data structure resides at a fixed place in each node's memory | ||
17 | * and is used to communicate between the master processor and the slave | ||
18 | * processors. | ||
19 | * | ||
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. | ||
