dumb: мне кажется, ответы 2 и 4.

  1. не 1: в openmp тоже только разделение и слияние.
  2. не 3: openmp содержит средства синхронизации, а о средствах межпроцессной коммуникации в pthreads я не слышал.
  3. со второй половиной ответа 4 готов согласиться: потоки win32 могут все, что может openmp, но не наоборот: например, openmp не может управлять приоритетами потоков.

  • [1] OpenMP is a fork/join method for creating and terminating threads. You must specify the start and end of each parallel region.
  • [2] OpenMP quickly became an industry standard for compiler-based threading after its introduction in 1997. FIXME ссылки на pthreads, WinThreads
  • [3] FIXME
  • [4] FIXME
