Hi, This code was not ever functional in the 4.6 branch, so if you want it to work, try 4.5.7. But really there is no reason to want to build it any more - use the CUDA and OpenCL ports available in more recent GROMACS. Mark On Mon, Jul 16, 2018 at 6:47 PM Rajat Desikan wrote: > Dear all, > I'

Hi Szilard, Your advice was perfect: I've installed gromacs 2018_2 on my computer and I'm currently testing some sample runs which have speeded up 20 times! However, I consistently find that mdrun only selects one GPU when two are available. Why does this happen? *nvidia-smi* Fri Jul 20 12:22:26
