You're missing the point. What if you have 50 processes under different parents? That's where killall comes into play. Of course, they all roll up to one parent, init, but you don't want to kill that. It's much safer to reboot.

Well yeah, if you know what you're doing, killall certainly does what you want. The OP isn't versed in terminal, we're advising that Activity Monitor is a safer, user friendly version. And in this case, Parallels is safe to kill as a parent.
To provide another solution to the OP's question: try putting single quotes around the name, and the program name is case-sensitive. (EDIT: ah I see you tried the quotes already, single/double quotes makes no difference, the case does though).
