-# Master (OpenMP)
-**Master** is an OpenMP directive that restricts execution of a block to thread 0. Unlike [[single-openmp|single]], there is no implicit barrier. Other threads skip the block entirely and continue immediately, making it suitable for non-critical side effects like printing progress or updating a log counter where stalling the whole team would be wasteful.
-```c
-#pragma omp parallel
-{
-    do_work();
-    #pragma omp master
-    printf("iteration %d done\n", iter);  // thread 0 only; no barrier
-    do_more_work();  // all threads, including thread 0, continue here
-}
-```
-Use `single` when the rest of the team must wait for the result; use `master` when the block is incidental and the team should not be held up.
