Shell Programming and Scripting
Remote simulation and 'at' command

Hmmm I just run two terminals, and then I'm logging 2 times in each window. One window is used for remote commands and the other one for htop.
I can see every action I made in the first terminal by observing the htop in the second window. I see when the cpu load bars are rising due to mpirun action, and when they decreasing suddenly after closing 'remote commands' terminal.

Ok, I found the solution. It's screen command.
One can simply do as me. Type:
1) screen
2) here you can put any of your commands that suppose to stay in a background. I put here my:
mpirun -np 8 compressibleInterFoam -parallel > log.txt &
3) press ctrl + a + d // and you are free
you can close the terminal if you want or just logout
In order to get back to the screen, type:
1) screen -list // as a result you will get all of the screens and numbers of processes
2) screen -r <number> // reattach you to the screen denoted by number of the certain process.
Thanks for advice

multinode_server
MULTINODE_SERVER(1) MORSE MULTINODE_SERVER(1) NAME
multinode_server - Server program to synchronise several instances of MORSE SYNOPSIS
multinode_server [synchronisation delay] DESCRIPTION
Socket server program to synchronise several instances of MORSE (nodes) running the same simulation scenario. This program must be started before launching the simulation in the nodes. All the client nodes will connect with the server and send it the updated positions of the robots they manage. The multinode_server program will concentrate the positions of all robots into a single Python dictionary, and then send it back to all clients. It also permits pausing the simulation, by typing in its terminal p and Enter. The same command will allow the simulation to continue. This mechanism relies on the fact that the clients will remain waiting for a reply from the server before continuing with the simulation. PARAMETERS
[synchronisation delay] Optional parameter that defines the delay (in seconds) between messages to the connected clients. A larger delay will slow down the simulation in all clients. Default value is 0.0 SEE ALSO
