These kinds of messages are symptomatic that you compiled your
applications with one version of Open MPI and ran with another. You
might want to ensure that your examples are compiled against the same
version of Open MPI that you're running with.

which is weird, I'm not sure what's wrong, but one thing that I
realized is that the documentation for running openmpi is outdated?
here's my $PATH and $LD_LIBRARY_PATH
[hpc@localhost ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/lib/openmpi/1.2.5-gcc/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/openmpi/1.2.5-gcc/lib
export PATH
export LD_LIBRARY_PATH
unset USERNAME
It's different that what the documentation had, because there's I
couldn't find the files in the /opt/openmpi
I hope that anyone could help?
Thanks a lot!
