mpirun--> output be written in both Log file and Terminal
 

Hi,

How can i use parallel run and have output not only in log file, also in terminal window.

Only in log file:
Only in terminal:

Option 1) Try 'tee'. E.g.

Check the man pages for 'tee'

Option 2) Redirect the output to a log file like for your first command:

and then use the -f with 'tail' to view log file dynamically:

Option 3) Use screen:

Open an new screen:

Launch your job:

Detach your screen: CTRL+A+D

Reattach your screen to view your running job later:

I prefer #2 if I'm running on a local workstation and #3 if I'm running remotely. 'screen' is the most flexible and powerful method - I would suggest spending some time to learn how to use 'screen'. Look in the man pages or check the web.

Isn't dumping it all to both screen AND file a bit unnecessary? Why not output it to log and use 'tail log' to look at the log file? Or if you're interested in looking at residuals use foamLog / pyFoam.

Thanks, i will try to do your suggestions.

I was lurking and saw this thread. I got a solution that might help others (since the post is old).
On a second terminal, use this command:

someone gave me that tip to avoid excess of process on simulation.
