Dear Geonwoo Lee,
<div><br>
</div>
<div>To avoid this error you have two possibilities:</div>
<div><br>
</div>
<div>- you can add the pencil decomposition, using -pd .true. in the mpirun line. This will make your calculations run, but probably not efficiently.</div>
<div>- you can decrease the number of nodes and <span style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">play with the combinations of nodes/k-points.</span></div>

</span></font></div>
<div><font color="#000000"><span style="caret-color: rgb(0, 0, 0);">Hope this helps.</span></font></div>
