[gmx-users] gpu-performance reduces during FEP calculation

Dear Gromacs users
I am trying to perform Free energy peturbation calculation in presence of
distance, angle and dihedral-restraint for a protein-ligand system.
However, I am finding, on turning on the FEP calculation, the performance
of gromacs5.1.1. in a gpu-based workstation significantly gets reduced. the
gpu/cpu ratio reduces from 1 to 0.234 on turning on FEP module. I was
wondering whether FEP-module is still not using gpu-based optimization.
