I am running a GW PPA calculation of a rather simple bulk material. I am getting a series of warnings

[WARNING] [CPU 0] has no poles

[WARNING]Allocation attempt of X_poles_tab of zero size.

[WARNING]Allocation attempt of ordered_grid_index of zero size.

[WARNING]Allocation attempt of coarse_grid_index of zero size.

[WARNING]Allocation attempt of bare_grid_N of zero size.

[WARNING]Allocation attempt of coarse_grid_Pt of zero size.

[WARNING]Allocation attempt of poles of zero size.

[WARNING]Allocation attempt of Ein_poles of zero size.

[WARNING]Allocation attempt of poles of zero size.

[WARNING]Allocation attempt of Ein_poles of zero size.

[WARNING]Allocation attempt of X_poles of zero size.

[WARNING]Allocation attempt of X_Ein_poles of zero size.

<snip>

and then at the end of the calculation a collection of NaN

What could be the origin of this problem? I tried starting from scratch, i.e., from the QE calculations but I hit the same wall again.

Thanks,

Roberto
