We create a set of tasks in a single region. We defines a variable named sum unequal zero which gets declared firstprivate for each task. Now each task calcualtes a sum using this private variable. Before each calcualation step we introduce a flush command so that maybe the private variabel gets bad. At the end we check if the calculated sum was right.</ompts:testdescription> +<ompts:ompversion>3.0</ompts:ompversion> +<ompts:directive>omp task firstprivate</ompts:directive> +<ompts:dependences>omp single,omp flush,omp critical</ompts:dependences> +<ompts:testcode> +#include <stdio.h> +#include <math.h> +#include "omp_testsuite.h" + +int <ompts:testcode:functionname>omp_task_firstprivate</ompts:testcode:functionname> (FILE * logFile) +{ + int i; + <ompts:orphan:vars> + int sum = 1234; + int known_sum; + int result = 0; /* counts the wrong sums from tasks */ + </ompts:orphan:vars> + + known_sum = 1234 + (LOOPCOUNT * (LOOPCOUNT + 1)) / 2; + +#pragma omp parallel + { +#pragma omp single + { + for (i = 0; i < NUM_TASKS; i++) + { + <ompts:orphan> +#pragma omp task <ompts:check>firstprivate(sum)</ompts:check> + { + int j; + for (j = 0; j <= LOOPCOUNT; j++) { +#pragma omp flush + sum += j; + } + + /* check if calculated sum was right */ + if (sum != known_sum) { +#pragma omp critical + { result++; } + } + } /* end of omp task */ + </ompts:orphan> + } /* end of for */ + } /* end of single */ + } /* end of parallel*/ + + return (result == 0); +} +</ompts:testcode> +</ompts:test> |
