[CP2K-user] [CP2K:15589] Stuck when using BFGS

[Krack Matthias (PSI)]

Hi

It seems that is an issue rather related to ELPA than to BFGS. specifically, because BFGS involves a diagonalization of the Hessian whereas LBFGS does not. When BFGS works with ScaLAPACK, the problem stems most likely from ELPA. There have been issues observed with CP2K/ELPA, recently. So, just use ScaLAPACK, since the advantage of using ELPA instead of ScaLAPACK is most likely minor for your case.

Betreff: [CP2K:15589] Stuck when using BFGS

Hi,

I'm a new user of cp2k v8.2. When I do GEO_OPT using BFGS, it has been stuck many times in the step "OPTIMIZATION STEP: 1" as shown below without showing any errors. If I don't kill the job manually, the job will just keep running without printing any new results. This does not occurs when using SCALAPACK instead of ELPA or using LBFGS/CG instead of BFGS. I'm wondering is there any way to solve this BFGS issue? Thanks.
