There are new features coming in 19.05 for GPUs to better support them. 
You could then submit a 5 task job requesting --gpus-per-task=2 to 
achieve that (4 tasks on the first node and 2 on the second).

 From the release notes:


  -- Add GPU scheduling options for salloc, sbatch and srun:
    --cpus-per-gpu, -G/--gpus, --gpu-bind, --gpu-freq, --gpus-per-node,
--gpus-per-socket, --gpus-per-task and --mem-per-gpu.

All the best,
