I've got applications called Apple Qadministrator and QMaster, and I've tried to find out what they are by searching the web but I can't make much sense of what I've found in musical terms, although they appear to be connected to Logic.
Qmaster is an application for distributed processing in a cluster environment. The connection to Logic is the app Compressor that comes with Logic Studio. If you use Compressor to encode video/audio files and have a couple of Macs connected to your network then you can setup up a computer cluster where all the machines chew together on the processing task cutting down your render time. It is a little bit tricky to set up and can get very fast very geeky. But when it works it's amazing: Render farm for the rest of us.
