openmp is a compiler library, available in gcc since v4.2, for giving hints to a compiler about where code can be parallelized.say we have some code12for(int i=0; i<HUGE_NUMBER; ++i) deadHardCalculation(i)we can make this run on multi threaded by simply adding some pragmas123456#pragma omp parallel num_threads(4){ #pragma omp for for(int i=0; i&lt;HUGE_NUMBER; ++i) deadHardCalculation(i);}compiling with -fopenmp will generate an app that splits the work of the for loop across 4 threads.there’s support for dynamic / static scheduling, accumulators, all sortsthis tute is awesome.it increased the speed of my shingling code by 350% on a quad...
