Running Parallel in Batch mode
Hi all,
I am trying to run CFX 5 in parallel in a linux cluster. I've read that CFX needs to have the master node specified in order to run, however I am not allowed to use it, as it is normally the case in universities. I´ve seen in a thread in this forum that if I log into one of the nodes to be used, it should work, but it is not working for me. Here is my command file: Code:
INPUT=./CFXRunBolhaL200m.def The error: Quote:
Code:
ssh n12 cfx5solve -par-dist \"n12*4,n13*4\" -def $INPUT -double -chdir /home/luizadler/CFX -start-method \"Platform MPI Distributed Parallel\" -batch Quote:
Another question is how can I follow the solution once it is running correctly? No need to see the monitors (unless it is easy), but it would be useful to see the residuals. I've done this kind of stuff with fluent, but now I need to do it with CFX which is quite different.... Thanks for the help!! |
Would this be an installation problem in the cluster? Or the commands are wrong? Right now we are changing the person responsible for the cluster, hence I can't check if it is an installation problem, but it would helpful to know if this might be the case.

Yes, you have not installed distributed parallel for CFX properly. CFX has a separate distributed parallel setup procedure - see the installation guide for details.

Thank you!

Hi Luiz,
There are a few different problems here.
After you get this going we can check for other errors. Cheers |
Hi Bruno,
Thank you for your help! I've done what you wrote, however I still have the following License problem: Code:
+--------------------------------------------------------------------+ Any thoughts? Thanks again, Duda |
Hi Luiz,
Both the error cause and the answer are right there at the error message: Error cause: | The solver is unable to continue because of licensing problems. | What you should check: | 1) The license server is specified correctly and is running. | The compute-nodes are probably not properly configured to check out licenses from the license server. Apply to the compute nodes the same procedure you did for the master node regarding license configuration. The documentation also explains how to do that. Abraço |
Thanks again Bruno. I am trying to sort it out, and I will post here again as soon as I have something solved :)
Abraços! |
