Dear Piyush Sir, I tried increasing parameter along z to 10.0 A but it didn't work. It still works on 7 or less no of processors. Regards Vishal Gupta B.Tech. 3rd year Mechanical Indian Institute of Technology Ropar Rupnagar (140001), Punjab, India. On Wed, Aug 26, 2015 at 7:14 PM, Piyush Kumar

Dear Vishal, I think if you are not turning off the periodic boundary conditions, then your system is possibly wrong. By default QE works on periodic boundary conditions, so if you want to simulate a 2D system, then you should put some vaccum in the z direction, so that there is no interaction betw

I've been running an SCF calculation for a free Ni system on High performance cluster. The job runs fine with processors 7 or less but it always leads to segmentation fault if the no of processors exceeds 7. The job takes 4-5 days for the run. I think the problem is in the definition of cell parame
