<div>
<pre>The following program:
#include <stdio.h>
int main() {
int j = 0;
#pragma omp parallel for linear(j:10)
for(int i = 0 ; i < 10 ; i++) {
printf("i = %d, j = %d\n", i, j);
}
return 0;
}
prints the following unexpected result:
i = 3, j = 30
i = 1, j = 10
i = 2, j = 20
i = 4, j = 40
i = 7, j = 70
i = 6, j = 60
i = 5, j = 50
i = 8, j = 80
i = 9, j = 90
i = 0, j = 100
While I would expect the following:
i = 3, j = 30
i = 1, j = 10
i = 2, j = 20
i = 4, j = 40
i = 7, j = 70
i = 6, j = 60
i = 5, j = 50
i = 8, j = 80
i = 9, j = 90
i = 0, j = 0
or some other ordering of the prints with same values.
My input program may be wrong - happy to be told that!
Thanks
