+Gromacs was build on each of the nodes locally letting it select the optimal CPU (AVX, SSE) and GPU accelerators. The ''cmake'' flag -DGMX_BUILD_OWN_FFTW=ON yields a mixed precision compilation which is recommended. The we ran multidir options 01-04 on single GPU, and 01-08 and 01-16 on all 4 GPUs when possible.
