Using mpi is really amazing. I succesfully installed on a dual core processor for RegCM4. Using openmpi it cuts running time to half. Unfortunately, I have not successfully made installation for wrf.<br>On multiple nodes, you should have identical installation on each nodes. including the mpi's (regardless which kind it is). You have to install sshd and enabling automatic logins as well,so the master node can distribute the computational job to the other nodes<br>

<br>
I am about to install the WRF-3.4 model on my computer. According to the<br>
documentation<br>
mpich2 and/or openmpi can be installed to enhance functionality. As I am<br>
not a expert in the field of numerical computing,<br>
please apologise the probably stupid question I am going to ask.<br>
Should I install both mpich2 and openmpi on my system or just one of<br>
them? According to their descriptions, they implement the same<br>
functionality, but the examples in the WRF user's guide are with mpirun,<br>
i.e assuming mpich2. Can these two libraries actully coexist on a<br>
system, does this make sense? If they cannot, which one would you<br>
recommend? My system is Slackware64-13.37 kernel 2.6.38.4.<br>
<br>
<br>
Best regards,<br>
