Im trying to create a programm that displays value from different thread every second, as an attempt at progress tracking functionality, but unfortunatly i cant seam to correctly parallelise this case at all.

Here is my attempt:

#include <stdio.h>
#include <omp.h>
int i;
void print_every_second() {
    while(i<10000000) {
        #pragma omp flush
        printf("%d!n",i);
        sleep(1);
    }
}

void increment_to_10_million() {
    #pragma omp parallel for
    for( i = 1; i <= 10000000; ++i) {
        
    }
}

int main() {
    #pragma omp parallel sections
    {
        #pragma omp section
        increment_to_10_million();

        #pragma omp section
        print_every_second();
    }

    printf("Both threads have finished.n");

    return 0;
}

Functions end up not beign parallelised and only print_every_second ends up executing, at all. It is tested in VirtualBox with AMD Ryzen™ 7 2700 × 4 and gcc (Debian 12.2.0-14) 12.2.0
