This is my lab 3 for Operating System Principles course in XMU. The assignment guide see Nachos Project Guide of V22.0202-001 in New York University.
In this lab, I implement an EventBarrier primitive and alarm clock primitive first. Then use them to solve Elevator problem.
Now, you are in top directory. So, please enter into threads directory first.
cd threads
Compile the project.
make depend
make
Run the nachos. For the part 1 "Implementing an EventBarrier Primitive", you can use
./nachos -q 7 -t [num_threads]
where
-q 7: test the EventBarrier-t: number of threads
For the part 2 "Implementing an Alarm Clock Primitive", you can use
./nachos -q 8 -t [num_threads]
where
-q 8: test the Alarm-t: number of alarms
BE CAREFUL! Before you test the Alarm, please delete the comments in system.cc labeled with *** ADDED *** in lab 3.2 first.
For the last part "Synchronization Problem 2: Elevator", you can use
./nachos -q 9 -t [num_threads] -F [num_floors] -E [num_elevators] -c [capacity]
Command line parameters are:
-q 9: test the Elevator-t: number of riders-F: number of floors-E: number of elevators-c: capacity of a elevator
But, there exists BUGS when overloading occurs. Please FIX it!
Dasong Chen, Jinbin Tan and Hao Dong assist me to finish this assignment. Thanks for their effort.
