Ok, I freely admit that I'm resurrecting a dead conversation, but while
replying to another LAM list mail this morning, I re-discovered that we
have an SSI parameter to disable the "-n" option for the rsh boot
module.
mpirun -ssi boot_rsh_no_n 1 ....
Or setting the corresponding environment variable will disable the use
of the "-n" option in the rsh boot module.
So I guess I have to recant my previous statement -- I apparently
*have* met an rsh that doesn't like "-n"!
:-)
