CSCI-442 Spring 2016 Project 5 implemented by Jack Rosenthal. No unusal files in my submission outside of what was given, nor interesting features. I estimate I spent 3.5 hours on this project, most of which was spent figuring out the given starter code and the rules of the game.
My party_barrier enforces two rules:
- 4 players must be in the party to begin playing a hole
- The party may not start the next hole until they have finished the current.
My hole_signalling condition enforces that only a single group may play the
hole at a time, using the help of a mutual exclusion. (See lines 87--92 in
player.cpp). The corresponding notify_all call allows the waiting golfer
to continue the condition check.
If two groups are waiting on a hole at the same time, at lines 87--92 a single thread will be waiting on the hole. It is non-deterministic which thread will be here, and thus, one group can pass another.
