If you want it to be automatic, then you can override your typical make command to be an alias to itself in your .bashrc in your home directory.

Example:

alias make="make -j"

Or you could do something like:

alias jmake="make -j"

in the case that you don't want to override it, but want a quick and easy (and memorable) way to run make in parallel.
