Hi,
Probably, as Nihar suggested, channel bonding is te best way to go in
your case. However in LAM 7 you can use different IPs to communicate with
different host names ( lamboot parameter "-l" ). So calling the other
host with two names and seting up the lamhosts (and of course the
/etc/hosts ) file accordingly will do the trick.
Cheers ,
Roberto
