I'm sorry - I can't even make sense of this. If you think you can
reproduce it, then you are welcome to fix it. I cannot reproduce it,

Hi Ralph,
I can recreate this failure, I think it caused by the fact that we
do not open orted on the last node( also I didnt check it ), since
np < number of hosts.
I used the falowing configure line ../configure --prefix=/home/USERS/
lenny/OMPI_ORTE_TRUNK
on OMPI 1.4a1r19522
Hope it helped.
