Re: Configuration's effect on optimization [SOLVED]

Hi Jordan,

Using --enable-avx-safe-mode seems to have solved the problem - thanks!

There is a small difference between energies and forces from the start of the calculation; this persists for 6 MD steps at which point the forces begin to diverge.

Configuration's effect on optimization [SOLVED]

I have two builds of 8.0.8, one on a local machine and one on a HPC cluster. When performing structural optimization using ionmov = 2, sometimes the local build is able to complete the optimization normally but the cluster build shows worsening SCF convergence with each MD step and then crashes. I'v...
