I wanted to take out the maximum performance of my machine. So, I attached all available colors to a single process, being this one dependent on an iteration.

```
#! /bin/bash
[ -z "`echo $BIN`" ] && BIN="mpirun -np 12 /home/path"
for i in 1 2 3 4 5;do
# setting input 
$BIN &
mv output_file output_file_$i
done

```

When I open my nohup.out file I got the message that my output\_file is not there. I understand it but I want the process to finish, move that file and continue with different input parameters.
