I am a first year PhD student. I have a problem when I use the hse functional to calculate EuS band structure in the scf step. <br>
The <a href="http://scf.in" rel="noreferrer" target="_blank">scf.in</a> is below<br>

<br>
But it reports :<br>
Error in routine mp_start_bands (1):<br>
n. of band groups must be equal to parent_nproc if 3D-FFTs are used. To remove that restriction, recompile without __USE_3D_FFT flag.<br>
<br>
How can I fix this ?<br>
Thanks so much !<br>
<br>
Best,<br>
