[gmx-users] Trouble balancing GPU/CPU force calculation load, ratio = 0.09

I am simulating a protein in water and am concerned that I am not using my hardware to the best of it’s abilities. Here (https://drive.google.com/file/d/0BwAaTxAET7c5VkZERkFsa1cyRlk/view?usp=sharing <https://drive.google.com/file/d/0BwAaTxAET7c5VkZERkFsa1cyRlk/view?usp=sharing>) is the log file from a 1 nanosecond simulation. The only piece of information missing from it that may be of use is that I am using the OPLS/AA force field. Additionally, GROMACS only seems to be using 8-12 cores of the 64 available despite it’s complaint that the GPU is being underutilized. Please take a look and if you can, give me some advice about improving my simulation efficiency.
