Hello everyone,
I'm trying to run an OpenFOAM simulation on two hosts on my home LAN.
I've managed to make the hosts communicate via ssh without giving
passwords as instructed on Open MPI web page.
The problem with running mpirun is in the enviromental variables for the
non interactive login bash
Hi,
One workaround is you can define PATH and LD_LIBRARY_PATH in your common
.bashrc and have a resembling paths of installation in two nodes. This
works for me nicely with my three node installation :).

Thank you very much for the advice. Actually I'm running O
Hi Tomislav,
I also had this issue. When you try to trace it, you'll find out that
when you manually connect to a machine and immediately execute a
command, it will inherit your environment, not the environment of the
node. See:
$ ssh node1 && echo $PATH
This will echo the PATH on your computer,
Hi,
common bashrc meant if the /home is network mounted so ignore that I guess.
Have you tried adding
. $HOME/OpenFOAM/OpenFOAM-1.5.x/etc/bashrc to your ~/.bashrc on nodes ?
This will append the configurations you need from the bashrc file located
inside the directory.

Hi, $HOME means your installation directory (some/path as you mentioned).

I'm sorry, I was wrong. You typed it correctly. AFAIK, this command logs
in your node but the PATH variable is still just as on your master. I
had this issue and I solved it by editing the .ba

The .bashrc on your master is not run, therefore there are no echos.
Let's revise once more so that we're sure we understand each other :-)
On your master - on the computer you run "mpirun" - you put these 2
lines into your own .bashrc:
export PATH=$PATH:/openMPI/bin
export LD_RUN_FLAG=$LD_LIBR

Okay, now it's getting more confusing since I just found out that it
somehow stopped working for me!
Anyway, let's find a solution.
I found out that there is difference between
ssh node1 echo $PATH
and
ssh node1 'echo $PATH'
These command give you different output. 'man ssh' states that it sets

In this case the $PATH variable is expanded by the shell *befor

I'm sorry, I can't help you with NFS. I have never had it on my network.
Good luck anyway... :)
