No, it's not an input parameter of QE. Try to run your job on a different machine. PG On Mon, Feb 3, 2020 at 8:27 AM Pooja Vyas wrote: > I even tried reducing my k-points from 11*11*11 to 3*3*3. but still the > run gets terminated with signal 9 error. > > On Mon, Feb 3, 2020 at 12:55 PM Pooja

Respected sir, I don't have any idea about the time limit which you are talking about. Is it any parameter of the QE input file? On Mon, Feb 3, 2020 at 12:53 PM Paolo Giannozzi wrote: > Yes, but it is much larger than that (115 days). I was referring to a > maximum limit set by your batch

Yes, but it is much larger than that (115 days). I was referring to a maximum limit set by your batch queue system, or by your operating system. Paolo On Mon, Feb 3, 2020 at 5:32 AM Pooja Vyas wrote: > Respected sir, > Is there any default value of time after which the run can terminate by >

Hi, Always compare the energy per formula unit, if you do that in your case there is a small different in energy which may be due to different k-grid and energy cutoff. I think it is better to optimize the kpoints and energy cutoff for particular unit cell or supercell. On Sun, Jan 19,

Hi Pooja, I think CaO is a cubic crystal. You can use VESTA to generate a supercell. It can take .cif file. Play with it. I believe extending lattice parameter 2X2X2 generate a 36 atom supercell. HTH Manu (McMaster University) On Sat, Jan 18, 2020 at 12:38 AM Pooja Vyas wrote: > Respected

Well, maybe because in your first calculation you had two atoms, and 64 in the second one.You should try to see if multiplying -107.10 by 64/2 improve the comparison L. On 16/01/2020 06:23, Pooja Vyas wrote: Initially I had run my input script with ecut=100Ry and k-points= 11 11 11 1

Dear Pooja, All seems fine. Note that calculation of (2x2x2) supercell takes considerably longer than that of the (1x1x1) unit cell. Are you sure you need that high cutoff energy and that dense k-point grid? If you reduce these two then the calculation will run faster. Best regards, Tone Kokalj
