Dear Xavier Thank you for the detailed information. Yes I have already used pseudo potential from the PseudoDojo library and observed exactly what you have described. After the VC-relax the verification the verification scf calculation showed a completely different pressure tensor. I did not increa

[QE-users] Parallel computing of QE7.1 vc-relax crashes when using large number of processors

2022-10-28 Thread Xin Jin
Dear Quantum Espresso Forum, I encountered a problem related to the parallel computing using QE7.1 for vc-relax. I was trying to perform a vc-relax for a 3*3*3 BCC tungsten super cell. The code works fine for non-parallel computing, also works fine for parallel computing if the number of pro
