Some Issues Involved in Parallel Programming

• Deadlocks, Livelocks.

• Data Races (Synchronization)
  • A race condition is a kind of error condition peculiar to parallel programs. The outcome of a program changes as the relative scheduling of units of execution (UEs) varies. This is often the result of modications to a shared or global variable by more than one UE without an appropriate synchronization mechanism (such as a barrier, mutex, or semaphore).
• Load Balancing
