        <span style="font-family:Arial;">Dear Prof. Blaha and Prof. Marks,</span>
</p>
<p style="font-family:SimSun;">
        <span style="font-family:Arial;">   I have changed my compiler to ifort<span style="font-family:Arial;">(</span><span style="font-family:Arial;">2019.4.243) + mkl (19.1.2), and used the options recommended by Prof. Marks. Now I get the same result from two directories. </span></span>
</p>
<p style="font-family:SimSun;">
        <span style="font-family:Arial;"><span style="font-family:Arial;">  Thanks for your response and support.</span></span>
</p>
<p>
        <span style="font-family:Arial;">Best regards,</span>
