Discussion Notes for Week

• Mid Exam 1: Wednesday, February 24
• Java applet: CPU Scheduler Application

Sample application: Bounded buffer (see also Section 6.6.1)

• Makefile
• Base: bad_produce_consume.c
  make bad
  Problem: no protection of the critical sections
  Proposed solution:
• sem_produce_consume.c
  make sem_pc
  Problem: busy wait
  Proposed solution:
• bounded_buffer2.c
  make sem_count
• Also, see Project, pp. 236 - 241

From today's discussion, you should learn

• Operating system primitives for synchronization
• How an application can use them
• Debugging hints

Do not expect what you do not inspect.
If you don't look at it, do not count on its being right.

Especially remember that when you are the boss!
