Laboratory Exercises On Task Scheduling
1. Implement a Linux process that is executed at the default priority for a user-level application and waits on a binary semaphore to be given by another application. Run this process and verify its state using the ps command to list its process descriptor. Now, run a separate process to give the semaphore causing the first process to continue execution and exit. Verify completion.
2. Create An Application That Creates Two Tasks That Wait On a Timer Whilst the Main Task Loops.
3. Develop an Applications Using Linux
4. Design of Plant Control System
TOTAL:45+30=75 PERIODS
