I am working on Fluent parallel processing too. Your problem should come from your clutser master node. The error said it could not get port in my understanding the port may be occupied by some other application. The most possible situation is that you did not close the previous parallel run, or it corruped but you did not clean it.

You welcomed to send me emails with furthur details. I am also working on fluent cluster now.

Sir,

I am very new to this fluent parallel processing. I was trying to run a case in fluent with two processors(one is my system where the fluent is installed and other one is my neighbouring system). But i was getting error in doing so. Can u please tell me the step by step procedure for running a case in fluent parallel processor.

Thank you very much sir.

But my previous Fluent parallel run hung with same error,can you tell me how to clean out the error ? Other applications using MPICH are working fine on this cluster.. only with fluent Iam facing this problem of "Error getting port number of service!" Can you tell me if any manual settings are needed to resolve this, I have followed all instructions on Fluent support site for parallel runs.

Regards, Sampath.

Suggestion to both:

There is complex situation when running fluent parallel. Please make sure the master node can rsh peer without password. Make sure same dir shared on master node and shared peer, etc. So I suggest you can run a fluent parallel case on single computer(maybe master) first, using process paralleling, that what I did while having such problem. So that you can tell the problem came from master or from the connection between master and other nodes.
