[gmx-users] pp/pme ratio differences between gromacs 5.0.x and 5.1.x

[Johannes Wagner]

hey guys,
came across an issue with pp/pme ratio difference from 5.0 to 5.1. For a system running on 2 nodes with a pp/pme ratio of 80:16 on 5.0, the same thing starts with 72:24 on gromacs 5.1. The 5.1 run has a much higher load imbalance and is hence slower. Are there known changes from 5.0 to 5.1 in the pp/pme ratio that cause this?

cheers, johannes
