RTEMS C User's Guide
A processor in a RTEMS system is referred to as a node. Each node is assigned a unique non-zero node number by the application designer. RTEMS assumes that node numbers are assigned consecutively from one to maximum_nodes. The node number, node, and the maximum number of nodes, maximum_nodes, in a system are found in the Multiprocessor Configuration Table. The maximum_nodes field and the number of global objects, maximum_global_objects, is required to be the same on all nodes in a system.
The node number is used by RTEMS to identify each node when performing remote operations. Thus, the Multiprocessor Communications Interface Layer (MPCI) must be able to route messages based on the node number.
