Hi everyone,
I've installed Fluent 6.3.26 on Ubuntu 10.04 64bit and now I want to user parallel processing. But I have a problem: After my settings (default interconnection=>ssh) I click on Run button on File->Run menu, the following message appears: Code:

Do you have fluent installed on all the nodes in your cluster, or have you setup an nfs share?

No, I haven't installed on clusters! I thought that fluent will do it itself (by ssh with no pass!). I should do that? How about NFS? Please tell me more. I can't find any tutorial to use parallel fluent, but I'm using fluent on my system successfully.
Any help is appreciated. Thanks in advance |

And I have disabled ufw and apparmor. I installed fluent on clusters and now with default interconnection, error is changed to this:
Code:
mpid: cannot connect to mpirun(127.0.1.1, 34671): Connection refused! - Any other service should be installed or started (or something to stop) because of "connection refused" - Any more configuration for ssh? why fluent tries to connect 127.0.1.1 instead of 127.0.0.1 ? what is mpt? it should be installed or configured? it can't even connect ! Would mind help me with fluent and nfs sharing? Thanks a lot |

You need to do either of the following:
1. Install FLUENT on the same location on all the involved machines OR 2. Run FLUENT from a NFS directory, and make sure all the involved machines can access the FLUENT installation with the proper permission Anyway, I recommend you to use FLUENT 12.1.4, instead of 6.3.26. |
