Activate OpenMPI on Fedora 17/18/19

On Fedora 17/18/19, and some previous version, there is no default link to OpenMPI binaries and libraries. On 64-bit system, they are located in /usr/lib64/openmpi/{bin,lib,share}. To activate them for everyone to use, we have to make some changes as follows.

For OpenMPI's libraries

$ sudo /bin/sh -c 'echo "/usr/lib64/openmpi/lib" >> /etc/ld.so.conf.d/openmpi-64.conf'
$ sudo ldconfig

For OpenMPI's binaries

$ sudo echo 'export PATH=/usr/lib64/openmpi/bin:${PATH}' >> /etc/profile.d/openmpi.sh
$ sudo echo 'set path = ( /usr/lib64/openmpi/bin ${path} )' >> /etc/profile.d/openmpi.csh

Exit your terminal screen and open it again to activate the new settings.

Done!

@10/Jul/2013: I have made a minor change in title and change the double quote to single quote of the echo command to keep ${PATH} from auto-expansion.
