CMSC 335 Spin Locks Known as A Low Level Synchronization Discussion

I’m working on a computer science discussion question and need an explanation and answer to help me learn.

• take one of the topics in the readings,
• find a reference outside our readings talking about that topic
• cite your reference
• tell us a little about how the two presentations relate to each other
• tell us what you have learned about that topic from your readings

Some suggested topics:

1. Spin locks
2. Atomic read/write operations vs the real world
3. Sequentially consistent memory
4. Memory barrier instructions
5. Test and set locks: getAndSet (), compareAndSet ()
6. Monitors, locks, conditions
7. Locked queue
8. Lost wake up events
9. Readers writers locks
10. Reentrant locks
11. Semaphores
12. Threads – creating and running them
13. Thread structure of the JVM and the Java GUI classes
14. Race conditions and deadlocks
15. Writing a concurrent program
    1. condition variables
    2. producer-consumer problem
    3. finding objects
    4. active, passive, and control objects

Following are good examples, in addition to what is provided in the course shell.
