It gives something that doesn't look to be terribly helpful: /tmp/launch-yTVXcz/org.macosforge.xquartz:0

Eric says that the tvok option isn't working because your the desktop doesn't know about the laptop because it isn't really part of the network.  He said the tv=local option should work, but your DISPLAY variable isn't set.  So he is now trying to figure out how/where the DISPLAY variable gets set.  What do you get if you type ssh onto the desktop and type "echo $DISPLAY"?

When we were waiting for the commands to be executed we looked at how the memory was being used, and it almost seemed like aips was completely unaware of the system resources it had, out of 19 (?) cores present on the machine it utilized only one of them, so the CPU rarely went above 2-3%.
