[gmx-users] gromacs-mpi bandwidth requirements

[Jack Howarth]

    I have several dual processor Xeon boxes available on which
I have installed lam 7.0.6 and gromacs-mpi 3.2.1. These boxes
are currently connected via full-duplex fast ethernet. What is
the bandwidth requirements of gromacs-mpi for typical md 
simulations? Would I see a major improvement in gromacs-mpi
performance if I switched the LAM over onto gigabit ethernet?
Or are the md simulations typically cpu bound rather than
io bound? Thanks in advance for any clarifications.
