Got it. Maybe this is why my get_highest_ready function was failing.
Also, how does the insert_ready function work? What are the rules for
a node being in the ready queue?
I am asking this because I need a list of all the nodes in the system,
which are either ready to execute or are currently executing on a
processor. How do I go about obtaining this list?
The current SMP schedulers maintain a list of scheduled nodes. These are
nodes which have an allocated processors. Nodes which are ready (they
don't have an allocated processor) are maintained in chains, tables of
chains, or red-black trees depending on the implementation.
