running openFOAM on network
Hi foamer
I am trying to run Openfoam on two machines, but I get this error: ssh: Could not resolve hostname r-soll41: Name or service not known The machine file is in text format and contains: r-soll34 r-soll41 and I am running from r-soll34. Do you have any idea why I get this error? Do you have any step by step manual showing how to set SSH settings on the machines? |
No guarantee, Mahdi, I'm just poking at some minor points having only minor experience with ssh-connected machines. But how do you try to use the machinefile?
If I remember correctly, the basic run command should look something like: mpirun -np 8 -hostfile machines rhoPimpleFoam -parallel with 8 being the number of your cores and "machines" being the machinefile. The rest should be clear, I think... If it really is a SSH-specific problem unfortunately I can not help any further. But the error message to me simply looks like the name of the remote host was passed on like a command, not like an option to sum run-program... |
you should edit you host file (ususally is in /etc/host but might depend on distro) and add a line with
r-soll41 iPAddressOfTheMachine in addition to this, have you set up passwordless ssh access on the 41 machine? what happens if you try to connect manually with ssh to the server? |
