Subject: [OMPI devel] ticket #1469
From: Lenny Verkhovsky (lenny.verkhovsky_at_[hidden])
Date: 2008-09-10 04:01:01


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.
