For higher performance over GigEth using low latency drivers you have the 
following options (given that your ethernet cards are among the supported 
ones):

SCore (MPICH1-based): http://www.pccluster.org/
GAMMA (MPICH1-based): http://www.disi.unige.it/project/gamma/index.html
EMP (MPICH1-based): http://www.osc.edu/~pw/emp/
And for commercial offerings:
Scali Connect:
