Writing correct and efficient parallel programs is more difficult than doing so for sequential programs. One of the challenges comes from the nature of concurrent execution of a parallel program by different threads. Determining exact concurrency is NP-hard [10], and is impossible for real-world programs at compile time.
OpenMP provides an easy and incremental way to write parallel programs. The well-structured OpenMP constructs and well-defined semantics of OpenMP directives make compiler analyses more effective on OpenMP programs than on more loosely structured parallel programs that are solely based on runtime libraries, such as MPI and Pthreads.
