<div dir="ltr"><div><br></div><div>Dear researchers</div><div><br></div><div>I want to perform GW calculation using Berkeley GW package. To begin with, however, I need bands simulation with a large number of bands using pw.x in QE. I am doing a calculation on hBN monolayer now. However, when I use more than 1000 bands in bands simulation I get the following error:</div><div><br></div><div> Error in routine cdiaghg (983):</div><div> problems computing cholesky </div><div><br></div><div>I have seen that the same error occurs for other materials when the number of bands is very large. Has anyone faced this error before? I will be very grateful if someone could suggest a way around this problem.</div><div><br></div><div>Thanks in advance</div><div><br></div><div>Kanak Datta</div><div>University of Michigan, Ann Arbor</div><div><br></div><div><br></div><div><br></div><div><br></div><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr">_______________________________________<div>Kanak Datta</div><div>Graduate Student</div><div>Electrical Engineering and Computer Science</div><div>University of Michigan, Ann Arbor</div></div></div></div></div></div>
