[gmx-users] strategy of clustering 10nodes ?

We'd like to set up our own cluster, none commercial products, firstly 10 nodes and go large later. If you are in a situation with 2users and 10nodes cluster, how could you split jobs / nodes? i.e. clustering nodes for multi-jobs like 2jobs (4nodes-6nodes, 8-2), 3jobs (4-4-2), or 4jobs(3-3-2-2) ? Is there anyone have similar system/situation?
And I wonder how important the network topology of cluster is to get the best performance. Do I need to optimize the hardware interconnectivities of nodes? For example, one group of 4nodes need to be connected each other, like ring topology. If so, do I need to compile Lam-mpi/fftw/Gromacs with a specific option to enable that cluster group configuration ?
Even though the size of simulation box will be another factor to answer to this question, I'd be happy for any reference data. I appreciate any help or suggestions in advance.
