Operating Systems - Dining Philosophers - Problem, Deadlock & Solution
Which concurrency control mechanism is most appropriate to simulate the resource sharing in the Dining Philosophers problem?
ABarrier synchronization among philosophers
BMutex locks for each fork
CCondition variables for philosopher states
DAtomic counters for fork usage
Step-by-Step Solution
Solution:

  1. Step 1: Identify shared resources

    Each fork is a shared resource between two philosophers.

  2. Step 2: Choose synchronization primitive

    Mutex locks ensure exclusive access to each fork, preventing simultaneous use.

  3. Final Answer:

    Option B -> Option B

  4. Quick Check:

    Mutexes prevent concurrent fork access [OK]
Quick Trick: Mutex locks directly model fork exclusivity [OK]
Common Mistakes:
MISTAKES
  • Confusing barriers with resource locking
  • Using condition variables without mutexes
  • Atomic counters don't prevent simultaneous access
Trap Explanation:
PITFALL
  • Barrier synchronization coordinates threads but doesn't control resource access
Interviewer Note:
CONTEXT
  • Tests understanding of appropriate synchronization primitives for resource sharing
