You can change the directory.  It is called "basedir" and it is set in 
simfactory/etc/defs.local.ini.  If it's not there already, you can add an entry


basedir = /path/to/simulations

where 'machine' is your local machine name.  You can determine your local 
machine name with "simfactory/bin/sim whoami".

If you want to run a job on a certain number of cores, you can use the options

--procs N

when you submit the simulation.

You may need to modify simfactory/mdb/machines/<machine>.ini and increase ppn 
to 4.

In very recent versions of simfactory, this is now set automatically when you 
run sim setup, but it's likely that in the version you have, it is set to 1, 
which prevents you from running on more than one core by default.
