"Map" step: The master node takes the input, divides it into smaller sub-problems, and distributes them to worker nodes.
The worker node processes the smaller problem, and passes the answer back to its master node.
Other members wishing to modify the data item must first contact the master node.
Each domain has a single "master node" and many "transit nodes".
Each node will have a primary port and a secondary port, both known to be able to send control traffic to the master node.
With the master nodes fused, the general scans of the ship gave the same results as if every circuit had gone.
Opening it returns a file descriptor of a master node and causes an associated slave node to be created.
This method allows multiple devices to share the bus without the need for a single master node.
When a master node is unresponsive, the first of the slave nodes will get promoted to a master role.
The master node can also act as a slave by replying to its own messages.
