Dear QE users, I am experiencing projwfc.x job crash on IBM LoadLeveler system for large cases, over thousand of cores. Other codes pw.x, bands.x work fine (qe6.1).
Sysadmins have confirmed that my projwfc.x job run out of memory affecting system processes on some nodes resulting in their crash. Is there a way around for the projwfc.x to use less memory by playing with parallelization options? I have used for SCF: -npool 18 -ntg 4 -ndiag 32, and wf_collect = .true. Is there a way to get estimation of used RAM? Thanks in advance, Martin Gmitra Uni Regensburg, Germany
