[QE-users] dvscf file from a grid ph.x run

2019-07-09 Thread Ankit Jain
Dear users, I have been trying to collect and merge .dvscf files from a grid example of ph.x and combine these files into a single file (like it was created from serial single job). So far I have little success on this. I searched on the mailing list and it seems that the similar question

[QE-users] 2D CODE WILL NOT WORK, 2D MATERIAL NOT IN X-Y PLANE

Dear users, I am running into a new problem while trying to perform a calculation on a 2D slab consisting of 4 unit cells in the z-direction with an additional molecule on top of an under-coordinated surface atom. When I try to run the code (in serial mode just for checking), I get this

Dear Michal, I will hopefully be able to share some new benchmarking results in the wiki soon, but for the time being the most accurate estimate is in this presentation: https://on-demand.gputechconf.com/gtc-eu/2018/pdf/e8340-porting-quantum-espresso-to-gpu-accelerated-systems.pdf . In the

Hello, if you put the loop at line 467 of PW/src/exx.f90 inside an 'IF(gamma_only)', the segfault should disappear. I'm just checking if that is the only fix needed. Fabrizio On Tue, Jul 9, 2019 at 12:27 PM Michal Krompiec wrote: > I got a similar segfault using a fresh installation of QE

I got a similar segfault using a fresh installation of QE 6.4.1, on a different HPC, this time with Intel 2018 compilers and ELPA, with the same input file and pseudos (SG15) as previously. I noticed that my molecule is a bit too high in the simulation cell (vs. the potential added by
