/****************************************************************************** * OpenMP Example - Combined Parallel Loop Work-sharing - C/C++ Version * FILE: omp_workshare4.c * DESCRIPTION: * This is a corrected version of the omp_workshare3.c example. Corrections * include removing all statements between the parallel for construct and * the actual for loop, and introducing logic to preserve the ability to * query a thread's id and print it from inside the for loop. * SOURCE: Blaise Barney 5/99 * LAST REVISED: 03/03/2002 ******************************************************************************/ #include <omp.h> #include <stdio.h> #define N 50 #define CHUNKSIZE 5 main () { int i, chunk, tid; float a[N], b[N], c[N]; char first_time; /* Some initializations */ for (i=0; i < N; i++) a[i] = b[i] = i * 1.0; chunk = CHUNKSIZE; first_time = 'y'; #pragma omp parallel for \ shared(a,b,c,chunk) \ private(i,tid) \ schedule(static,chunk) \ firstprivate(first_time) for (i=0; i < N; i++) { if (first_time == 'y') { tid = omp_get_thread_num(); first_time = 'n'; } c[i] = a[i] + b[i]; printf("tid= %d i= %d c[i]= %f\n", tid, i, c[i]); } return 0; }
