<div dir="ltr"><div><div><div><div><div>Dear all,<br></div> I'm trying to do a HSE scf
calculation for bulk magnetite with PWSCF v.5.4.0. However, the
calculation failed just after the convergence of scf with the error
message as below,<br> 'convergence has been achieved in 14 iterations<br>APPLICATION TERMINATED WITH THE EXIT STRING: Killed (signal 9)'<br><br>No
energy information was printed in the output file. I tried both norm
conserving and utrasoft pseudopotentials, but neither of them worked. My
input is listed below,<br> &CONTROL<br> calculation = "scf",<br>.............<br>/<br>&SYSTEM<br> ibrav = 0 <br> nat = 14,<br> ntyp = 3,<br> ecutwfc = 120, <br> nspin = 2,<br> starting_magnetization(1) = 0.0,<br> starting_magnetization(2) = -0.25,<br> starting_magnetization(3) = 0.25,<br> occupations = 'smearing',<br> smearing = 'gaussian',<br> degauss = 0.0008,<br> input_dft = 'hse'<br>/<br>&ELECTRONS<br> mixing_beta = 0.3<br>/<br>................<br>K_POINTS automatic <wbr> <br>8 8 8 0 0 0 <br></div>I appreciate any help!<br><br></div>Regards,<br></div>Hongsheng Liu<br></div><div>Department of Material Science<br></div>University of Milano-Bicocca</div>
