The docs have some info on uninstall:


But yeah, if you just want to uninstall & reinstall, you can just:

1) stop all the daemons (since you are throwing away the old config,
may as well kill -9).

2) remove the configuration files in $SGE_CELL (rm -rf)

3) And... there will be init scripts left behind in /etc, but I
usually don't install the init scripts when I am just fooling around
with the settings.

Using these steps, I could test the installation process very quickly.
