rsh typically uses ports in the 513-1023 range. With a 640 node cluster

Are there any standard solutions to this other than 'use ssh'? We
already have net.ipv4.tcp_tw_recycle = 1 in /etc/sysctl.conf
You are likely out of luck unless you hack the inetd/xinetd source to
allow non-privileged ports to connect.
Is there something in particular you are doing that requires rsh versus
other tools?
