COSC 3360/6310 2019 FALL

IMPORTANT NOTICE:

Make sure processes you created is killed properly. If it is not killed in the program, use ps -u "your username here" to find out what process is running now. Use kill "the process id" to kill a certain process.
Many students did not clear their semaphores before their program ends. This prevents others testing their programs. The manager of the server is cleaning them now. If you can still see your semaphore and shared memory after the program ends with the command ipcs, please clear your own semaphores and shared memory with the following commands.

ipcs -q | awk '{ print "ipcrm -q "$2}' | sh > /dev/null 2>&1;

ipcs -m | awk '{ print "ipcrm -m "$2}' | sh > /dev/null 2>&1;

ipcs -s | awk '{ print "ipcrm -s "$2}' | sh > /dev/null 2>&1;

Specifications:

1. When using EDF or EDZL to decide which request gets handled, you do not have to ensure that all deadlines are met and only apply EDF or EDZL when deciding on requests to serve.
2. The sample output given is just one possible sample output. I choose a more complicated scenario that may happen to construct the sample output. Considering the process you spawn in the Linux is controlled by the Linux, the execution order cannot be guaranteed and hence the output may vary. For instance, the arrival order of the requests from process_1 and process_2 may differ randomly.
