Looks like there is some strange interaction there, but I doubt I'll get
around to fixing it soon unless someone has a burning reason to not use tree
spawn when preloading binaries. I'll mark it down as something to look at as
time permits.

Thank you!
With the patch, --preload-binary option is working fine.
However, if I add "--gmca plm_rsh_no_tree_spawn 1" as a mpirun command line
option, it hangs.
# /mpi/bin/mpirun --allow-run-as-root --gmca plm_rsh_no_tree_spawn 1
--preload-binary --hostfile /root/.hosts --prefix /mpi --np 120 a.o
Okay, I found the problem and think I have a fix that I posted (copied EO on
it). You are welcome to download the patch and try it. Scheduled for release in
1.8.2
Thanks

Yeah, it doesn't require ssh any more - but I haven't tested it in a bit, and
so it's possible something crept in there.

Wasn't it on the list recently, that 1.8.1 should do it even without
passphraseless SSH between the nodes?

Supposed to, yes - but I don't know how much testing it has seen. I can try to
take a look
