If the crash is due to not enough RAM, maybe it will show up similar to the exhaustion of RAM crash with nlvdw [1] if that is the case by checking for example with: grep hf /var/log/syslog

Questions: Have you tried to run you calculations several times? How many cores/nodes are you using? Which kind of parallelization did you use (MPI or k-point)? Not related to the crash: for the convergence criteria, use something like at least "-ec 0.001 -cc 0.001" to have reasonably converged SCF iterations. ________________________________ From: Wien <[email protected]> on behalf of Yifan Ding <[email protected]> Sent: Saturday, May 15, 2021 8:00 AM To: wien Subject: [Wien] How to select the appropriate nband in hybrid functionals calculations Dear Prof. Fabien， Thank you very much for reading and helping to solve my question. I opened the file output.log, and there was only one line in it: > stop error I found the output.log file for a previous successful example of hybrid functional computation, which shows the following: ec cc and fc_conv 0 1 1 in cycle 2 ETEST: .9176672200000000 CTEST: .0349624 ec cc and fc_conv 0 1 1 in cycle 3 ETEST: .5190131650000000 CTEST: .0400105 ec cc and fc_conv 1 1 1 > stop
