This is fairly staight forward in LAM.  Let's say I have three suns:
robbie, chip and ernie.

robbie% hboot -c conf.lam -I "-n 0 chip 1 ernie 2"

chip% hboot -c conf.lam -I "-n 1 robbie 0 ernie 2"

ernie% hboot -c conf.lam -I "-n 2 robbie 0 chip 1"

A fixed port is chosen on all nodes.  If it is already used, change
it with the -p option inside the -I option above.  Otherwise it is
as if you ran lamboot.  You can now run programs repeatedly with
fast start-up.

There is a section explaining this procedure in more detail in
"MPI Primer / Developing with LAM".
