mpt_connect: error: connect failed: Connection refused [urgent]
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:
Host spawning Node 0 on machine "ubuntu" (unix). Code:
Host spawning Node 0 on machine "linlab-desktop" (unix). Thanks in advance |
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 |
[urgent] please help
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 |
Hi again,
more information: my /etc/hosts is like this: Code:
127.0.0.1 localhost mpt_connect:error: connect failed: Connection refused. I have configured ssh with no password and rsh is not installed. Thanks for any help |

Host spawning Node 0 on machine "my-laptop" (unix). Any help is appreciated. Thanks in advance |

run FLUENT parallel
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. |
Hi,
Still the same error: Code:
0: mpt_connect: error: connect failed: Connection refused Any help is appreciated |
