[QE-users] qe-6.3 to 6.6: crash of fs.x
Dear all, I am experiencing crash of fs.x when using versions 6.3, 6.4, 6.5 and 6.6 either. I'm running qe on the supercomputing cluster "galileo" at CINECA, Italy.

Re: [QE-users] qe-6.3 to 6.6: crash of fs.x
Thank you so much! Unfortunately fs.x continues to crash with the errors Error in routine fill_fs_grid (1): cannot locate k point in the .out file, and task #15 from fill_fs_grid : error # 1 cannot locate k point in the CRASH file. I can see that in the .xml file the k points are written inside the block. Can you address me in understanding where fs.x expects to find the k points but it does not find them, please? I also attach the bash script I submit, maybe I'm doing something wrong at this level... A marginal question, in the .out file I see a Fermi energy ~ 7.2 eV but in the .xml file I see a Fermi energy of ~ 2.6e-1. If the latter is in Ry, corresponds to ~ 3.6 eV rather than 7.2 eV... is this however fine?

Re: [QE-users] qe-6.3 to 6.6: crash of fs.x
Thank you! I followed the point 5) procedure using the Mg3Sb2 values and keeping as default values the ecutrho and nbnd, and using both K_POINTS automatic 60 60 40 0 0 0 and K_POINTS automatic 61 61 41 0 0 0 which should be centered in zero, but still get the same error "cannot locate k point" ... In the next days I'll try to follow the example since point 1) by computing also the bands, even if in principle I think I can run point 5) alone because it starts by repeating the scf calculation...I'll also try different meshes, eventually I'll be back to you (sorry) Patrizio Paolo Giannozzi ha scritto: I think you need to use an automatic zero-centered k-point grid with tetrahedra. There is an example of usage of fs.x, with some explanations, in PP/examples/example02. Data in the xml file is in atomic "Hartree" units, not "Rydberg" ones. The reason is that the former seem to be much more common than the latter. Paolo On Tue, Dec 29, 2020 at 3:39 PM wrote: Thank you so much!

[QE-users] [SUSPECT ATTACHMENT REMOVED] anomalous (perahps) crash of fs.x
Dear all, I am experiencing crashes of fs.x when using versions 6.3, 6.4, 6.5 and 6.6 either.

I do as follows, all the input files and job submission scripts are attached: 1) run a scf calculation 2) run a nscf calculation 3) run fs.x at step 3) QE crashes and I get in the .out file Error in routine fill_fs_grid (1): cannot locate k point and in the CRASH file task #19 from fill_fs_grid : error # 1 cannot locate k point Please, note that I asked to colleagues of mine at the University of Warwick, where they use QE on a HPC infrastructure (Tinis) with Lenovo NeXtScale nx360 M5 servers with 2 x Intel Xeon E5-2630 v3 2.4 GHz (Haswell) 8-core processors, to run QE with the very same input files, and they told me that everything run smoothly with NO crash... So, I suppose I'm doing a silly error in the submission script, or, as suggested by my colleagues at Warwick, there is a compiling issue on the CINECA machine I'm using.

[QE-users] pseudopotentials implemented in epsilon.x
Hello everybody, I run an electronic structure calculation using relativistic USPP, qe-6.8, after that I run epsilon.x and got the error message that USPP are not implemented. However, in the epsilon.x user manual I am not able to find which pseudopotentials are implemented, which I'd like to know before re-run the calculation. Here's the question, does someone know which pseudopotentials are implemented in epsilon.x? I guess from here https://www.paradim.org/sites/default/files/2019-05/Band_Structure_and_UV-VIS_Spectra.pdf that PZ are supported, but they are not available for all the atomic species I'm interested in...

[QE-users] seeking hints for nscf convergence in supercell
Hello everybody, I'm seeking advice to fasten nscf convergence (or make it possible). I'm using qe 6.8 to study Mg3Sb2 / Mg3Bi2 solid solutions, as first step I'm starting with a Mg3Sb2 2x2x2 supercell (40 atoms) to compare with simple Mg3Sb2 cell (5 atoms). The calculation track is scf --> nscf --> fs. For the simple cell it runs smoothly (and I'm confident it is okay as I compared with a colleague of mine relatively expert in DFT, not qe). For the supercell the scf converges in around 1 day of CPU time, but the nscf does not converge in ~ 12 days of CPU time - say 23 hours with 4 nodes, 6 tasks, 6 cpu-per-task, npool=24, are not sufficient to reach convergence. I attach the .in files for both scf and nscf, as well as the nscf out file. There are several eigenvalues not converged but I am not sure if this is the cause of the long time required for convergence (I've read in the forum this can be often regarded as a warning).

Re: [QE-users] seeking hints for nscf convergence in supercell
Hi Giuseppe, thanks a lot for your time and support! The answer to the first question is honestly no, I took ecutwfc to a colleague of mine (for simple cell, not supercell) and ecutrho for USPP from the qe indications, I'll work on this. For the sampling, the final purpose is transport calculations and I'm afraid this sampling can be already too rough. If it's too much, I'll go for Wannier, for which unfortunately I've no experience (not yet). I'll follow your indications and, if the case, I'll feel free to phone you :D Thanks!!! Patrizio Giuseppe Mattioli ha scritto: Dear Patrizio Are you sure you need ecutwfc=100 Ry and ecutrho=12*ecutwfc to converge US pseudopotentials? Have you performed convergence tests on simple systems or flicked through sssp tables (I see 30/240 for pslibrary US Mg and 40/320 for gbrv US Sb...)? However, for your nscf step you require a 45 45 31 k-points mesh. It's a lot of k-points. I don't know what is the purpose of your calculations, so I can't say if you are uselessly oversampling the Brillouin zone. But there is no free lunch... HTH Giuseppe PS maybe we are nearest neighbours, you may phone... :-D Quoting patrizio.grazi...@cnr.it: Hello everybody, I'm seeking advice to fasten nscf convergence (or make it possible). I'm using qe 6.8 to study Mg3Sb2 / Mg3Bi2 solid solutions, as first step I'm starting with a Mg3Sb2 2x2x2 supercell (40 atoms) to compare with simple Mg3Sb2 cell (5 atoms). The calculation track is scf --> nscf --> fs. For the simple cell it runs smoothly (and I'm confident it is okay as I compared with a colleague of mine relatively expert in DFT, not qe). For the supercell the scf converges in around 1 day of CPU time, but the nscf does not converge in ~ 12 days of CPU time - say 23 hours with 4 nodes, 6 tasks, 6 cpu-per-task, npool=24, are not sufficient to reach convergence. I attach the .in files for both scf and nscf, as well as the nscf out file. There are several eigenvalues not converged but I am not sure if this is the cause of the long time required for convergence (I've read in the forum this can be often regarded as a warning). So, since I have limited computational resources, before making many trial-and-error attempts I would seek hints and advices to understand if it is only a matter of make a more intensive calculation (I've read the restart mode is not recommended for nscf so I should ask for more nodes), or to improve the input file in an aware way.

[QE-users] info about setting celldm
Hello everybody, I'd like to have from you a proof/disproof of my understanding on the use of celldm for F space groups. I read in the instructions that QE uses the primitive cell, in the case of Silicon I mean for that the "slanted" cell having parameter around 0.387 nm and 60° angles, say like here https://www.iue.tuwien.ac.at/phd/ungersboeck/node27.html . However, in an example for silicon, here https://www.quantum-espresso.org/resources/tutorials/shanghai-2013/getting-started/lecture1.pdf , I see that in the case of silicon with ibrav = 2 the entered celldm correspond to 0.543 nm, the side of the "cubic cell". Thus, if I'm working with a F space group, ibrav = 2, I must use the cube side as celldm, ~ 0.54 nm for silicon. Is this correct? If I'd like to work with the "slanted primitive cell" with angles of 60°, which in silicon has lattice constant ~ 0.387 nm, how can I do? I apologize but I couldn't find this in any tutorial I found.

Re: [QE-users] Density of states and Volume
At best of my understanding, the DOS "as is" in units of cell volume, that is the unit cell volume is taken as unity, i.e. [ 1 / ( energy * UnitCellVolume ) ] where UnitCellVoume=1. To get it in units of cube meters, you should divide the DOS "as is" by the unit cell volume. For example, if the unit cell volume were 50A^3, then a DOS of 1 in 1/eV becomes 2x10^28 in 1/(eVm^3), makes sense?

If you plot it as is, you should give it units eV^-1. However, you could need the density of states per unit volume. In that case, you can easily obtain the unit cell volume of your system, divide the computed density of states by it, and then the resulting density-of-states-per-unit-volume has units eV^-1 au^-3 (if you express the volume in au^3). In this case, if you integrate over the energy, you obtain number of electrons per unit volume, that is, electron density.

[QE-users] help in understand why ph.x crashes with electron_phonon = 'interpolated'
Hello everybody, I'm experiencing a crash in ph.x but I cannot figure out the reason, so I ask you some suggestion if possible, please. I'm working on FCC Co with q-e/7.0 on CINECA cluster, if I use the following input file without the line electron_phonon = 'interpolated', it runs smoothly, but with the electron_phonon spec it crashes. verbosity='debug' tr2_ph=1.0d-17 prefix='Co' ldisp=.true. epsil=.false. lqdir=.true. outdir='./tmp' fildyn='Co.dyn' fildvscf = 'dvscf' electron_phonon = 'interpolated' nq1=10, nq2=10, nq3=10, !nk1=20, nk2=20, nk3=20 / In the output file (attached) it looks the code runs until the following point, which looks the first e-ph calc.

Re: [QE-users] Effective mass
Hi Mayuri, if you are interested in the effective masses relevant to charge transport (DOS mass and conductivity mass) in a semiconductor or insulator (with a bandgap) you can use the EMAF code https://github.com/PatrizioGraziosi/EMAF-code From QE you do scf --> nscf (finer grid) --> fs.x to save a bxsf file Then, the bxsf file can be used to be converted by a routine you can find in the link above and used by the EMAF code. You can write to me for info and support.

[QE-users] info about eigenvectors with matdyn
Hello everybody, I did a test on Si and got for example the following optical eigenvector: freq (4) = 15.673472 [THz] = 522.810745 [cm-1] ( 0.00 0.00 0.707107 0.00 0.00 0.00 ) ( 0.00 0.00-0.707107 0.00 0.00 0.00 ) Can you tell me if the coordinates of the eigenvectors are cartesian or crystal, please? Apologize if the question is trivial, I'd daresay they're cartesian but I couldn't find the info in any doc and I am not sure about...
