I am still not understanding.
Is your problem that you don't want to wait for the script to be done
on machine A before you go to machine B?
fork a separate process for each machine.
You could even do this in, for instance, a bash shell.
Given a script called myscript.py that takes a machine name as an argument.
for machine in `cat list_of_machines`
do
python --machine $machine myscript.py &
done
if you need to do this inside python see
os.fork https://docs.python.org/3.4/library/os.html
and make sure you read about the problems with ssl if
you care. https://docs.python.org/3.4/library/ssl.html#module-ssl
Most people don't need any more 'at the same time' than this.
Do you?
Laura
