It depends on how you configured Open MPI (i.e., ran the "configure"
script). If you don't specify, Open MPI will install itself into /usr/
local/bin. Or you can specify where to install it via the --prefix
parameter to configure. For example:
./configure --prefix=/opt/openmpi-1.3.1
Will put the executables in /opt/openmpi-1.3.1/bin, for example.
See the README file for a bunch of relevant information on building
and installing Open MPI.

hey Thanks a lot,
well, I build the open-mpi package on the Desktop of RHEL 4.7 and
then I followed the instruction to put the path, which I believed
were written as /etc/openmpi/bin and /etc/openmpi/lib, which there's
no such a path on my Linux installation.. I'm wondering if there's a
tutorial that specify the specific step that I need to take for RHEL?

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realized is that the documentation for running openmpi is outdated?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!
