[Pw_forum] problem with final scf calculation with vc-relax

2017-10-14 Thread Leonid Kahle
Dear developers, There are frequent problems with the "final scf" after the convergence of a vc-relaxation with the recalculated G-vectors. In this case, the volume grows during the vc-relax by 3.5%, and G-vectors are assigned from sticks:   dense  smooth PW G-vecs:    dense smooth

If you do not need OpenMP parallelization, just replace esm_cft_1z with cft_1z, comment out the call to esm_cft_1z_init. See this thread: https://www.mail-archive.com/pw_forum@pwscf.org/msg29701.html Paolo On Sat, Oct 14, 2017 at 4:28 AM, Rajesh wrote: > Dear qe users, > > I have compiled my

Dear Prof Giannozzi, Thank you for your reply. But I need openmpi parallelization. Can I still follow your solution? Or should I compile with non intel libraries? Thanks you. On Sat, Oct 14, 2017 at 12:40 PM, Paolo Giannozzi wrote: > If you do not need OpenMP parallelization, just replace esm_c

Dear Prof Paulatto , Than you for your response. I need to use qe for openmpi as well openmp but on separate workstations. I think openmp works better on multi-cpu pc and openmpi on multi node clusters. I am right? Thank you. On Sun, Oct 15, 2017 at 12:42 AM, Lorenzo Paulatto wrote: > On 14/10
