[QE-users] Problem for testing k convergence

2020-09-30 Thread Anupriya Nyayban
Dear experts/users, I was trying to check the convergence for an orthorohmbic system and got ecut convergence for 70. Later, I choose a smaller ecut of 40 for testing kmesh convergence to reduce the computation time. But, I observed a opposite pattern of convergence graph which is attached

Dear Rafaello, Are you using a local (preferably SSD-based) scratch drive, or a very fast parallel file system? Best wishes, Michal Krompiec Merck KGaA On Wed, 30 Sep 2020 at 15:05, Raffaello Bianco < raffaello.bianco...@gmail.com> wrote: > Dear QE users and developers, > > I am doing an

Hello Raffaello, the first thing you should do, is be sure that your are writing to some high performance filesystem. This is often called scratch in computing centers, to be sure you should ask the people responsible. cheers On 9/30/20 4:04 PM, Raffaello Bianco wrote: Dear QE users and

[QE-users] Huge difference between Wall time and CPU time in electron-phonon calculation

2020-09-30 Thread Raffaello Bianco
Dear QE users and developers, I am doing an electron-phonon coupling calculation in this way (I am using QE v 6.6). First, I have done an scf calculation. Then, I have done a phonon calculation where I have printed the dvscf files, with fildvscf = 'dvscf' Subsequently, I have done

Dear users, I’m trying to run the GWL first example (methane): the first step (scf) is ok, but on the second step (pw4gww) I got the following error: "Error in routine ggent (2): too many g-vectors” I used the input files included in the distribution. I also checked the output file reference
