<br>
I'm facing the error when using n_pool parallelization that says that <br>
some processor has no k-point.<br>
<br>
I learned this error appears when the number of n_pool in the <br>
parallelization is not a good divisor of the total number of k-points in <br>
a calculation.<br>
<br>
However, in this nscf calculation I'm running I have 216 K points and <br>
I'm using 216 processors with npool = 108 (see the output)<br>
<br>
So I assume each pool should process 2 k points (I have no symmetry).<br>
<br>
However, the calculation stops with the error in the subroutine <br>
divide_et_impera related on the k point division.<br>
<br>
Is there some other constraint in the use of npool that I am not aware of?<br>
<br>
Bests,<br>
