Error with parallel processing and ubuntu
Hello everyone!
Due to the fact that my models become more complex I am trying to process in parallel mode.
In serial mode everything works fine.

Even if I start a new simulation and choose "Parallel on Local Host" I get the following error:

Starting local server: /opt/CD-adapco/STAR-CCM+8.06.005-R8/star/bin/starccm+ -server -np 2
ssh: connect to host port 22: Connection refused
mpirun: Warning one or more remote shell commands exited with non-zero status, which may indicate a remote access problem.
My system is running on ubuntu 12.04.3, 64Bit.
Does anybody have an idea what's going wrong?

Any advice is appreciated.

Thank you.

You may have figured it out by now.

You need to look to see if your port is open.

Use the command netstat -an to see if the port that you intend to use is listening or open.

You can also change the port to say 27000 in the license file and see if this port is open as well.

Sometimes the ports are closed for network security in linux. See if you can check this.

Are you accessing a network license or is the license located on your computer?

Good luck!

Thank you for your answer.
I haven't solved it in the mean time but because of your answer I started checking the ports. I found out that the openssh-server wasn't installed properly.
Now everything seems to work fine.

Thanks again.
