Indeed, queuing systems are used on clusters to manage a large number of
simulations by different users. These are additional programs that are not
usually installed on laptops and local desktops, and cannot be controlled
by simfactory or the Einstein Toolkit. Therefore, every time you submitted
a simulation it started running immediately, i.e., in parallel with those
that you started before and presumably caused your laptop to crash.
If you want to run multiple simulations simultaneously you will have to do
so on a cluster. On your laptop you should be able to run small test
simulations, and typically one at a time.

Could you please send us the parameter and logfiles? Otherwise it is
difficult to access what goes wrong.
I suspect that your runs overwrite each other, since they seem to have the
same name and run in parallel. That is probably why only the last submitted
simulation actually runs. As an easy check you could submit two small runs
with different names.
