Sun Grid Engine (SGE) is a bath queue system that can be used to distribute computation intensive tasks across one or more servers/CPUs. SGE has a graphical configuration utility called qmon, but when you start it on a remote machine (using SSH), you may end up with errors like this:

Warning: Cannot convert string "-adobe-courier-medium-r-*--14-*-*-*-m-*-*-*" to type FontStruct
Warning: Cannot convert string "-adobe-courier-bold-r-*--14-*-*-*-m-*-*-*" to type FontStruct
Warning: Cannot convert string "-adobe-courier-medium-r-*--12-*-*-*-m-*-*-*" to type FontStruct
X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  45 (X_OpenFont)
  Serial number of failed request:  329
  Current serial number in output stream:  340

The warnings are not really a problem, but the error is. It can be solved by running the following on the client (i.e. your local) machine (assuming it runs Debian or Ubuntu):

sudo apt-get install xfonts-75dpi
xset +fp /usr/share/fonts/X11/75dpi
xset fp rehash
