That was our hypothesis after seeing the results.
One of our goals was to assess the readiness of som

Hi,
I have no idea what you're trying to show with these graphs. Your vertical

1) GROMACS doesn't use configure or fortran, so don't mention that

A few more things to add:
- we don't have CPU SIMD kernels for Power8, so comparing the plain C
kernels against AVX kernels on AMD is not exactly fair;
- as Mark pointed out, to use resources efficiently, you'll have to manage
thread affinity on Power8 (by default you'll need a stride of 8 to use o
Hi,
I have no idea what you're trying to show with these graphs. Your vertical

Hello there
We've been testing gromacs-5.1-beta1 in an IBM POWER8. The input used is
'pme.mdp' within the ".96" directory of the following benchmark:
