Can't seem to get rsh to scale past like 63 nodes with mpi jobs. SSH scales much higher, but the performance is a lot worse in customer benchmark tests. I'm guessing that I'm running out of pty's or tty's or something on the headnode. Anyone have some ideas? I believe the default pty's in 2.4.20 is 1024, but when I list /dev/pty I only see 256 entries. MAKEDEV -m 1024 didn't seem to do anything past 256.
