[QE-users] nscf calculation of 2x2x2 Si supercell

[Fariba Islam]

Dear all,
My  conv_thr=1e-20 and ecutwfc=200 ecutrho=800
My nscf calculation is crashing with the error

task #        10
     from c_bands : error #         1
     too many bands are not converged

How can I solve? From suggestions found online, I have reduced the
threshold and increased ecutwfc and ecutrho.
