Shared vs. Private Variables


Example of Code with No Data Dependencies
!Fortran example 

!$omp parallel do private(temp) shared(n,a,b,c)
do i = 1, n
temp = 2.0*a(i)
a(i) = temp
b(i) = c(i)/temp
enddo


/* C/C++ Example */

#pragma omp parallel for private(temp) shared(n,a,b,c)
{
for(i=1; i<=n; i++){
temp = 2.0*a[i];
a[i] = temp;
b[i] = c[i]/temp;
}
}
