    You might be pleasantly surprised

    Something like:
    Code:
    for (i = 0; i < 10000; i++)
        a[i] = b[i] * c[i];
    might be rewritten by a smart compiler into:
    Code:
    for (i = 5000; i < 10000; i++)
        a[i] = b[i] * c[i];
    
    for (iprime = 0; iprime < 5000; iprime++)
        a[iprime] = b[iprime] * c[iprime];
    broken into two simultaneous threads. Kewl, eh?
