Operating System Transition

We have upgraded the operating system (OS) at Glooscap from Red Hat Enterprise Linux 4 (RHEL 4) to RHEL 6. However, the head node is still running RHEL4, but will be replaced soon.

Storage reorganization

As of Feb 20, 2012, the /globalscratch filesystem has been merged into the /home filesystem, so most users on Glooscap will now have a single quota rather than two, and /home/$USER/scratch is no longer a symbolic link to /globalscratch/$USER. If you have scripts which make explicit reference to /globalscratch/$USER as part of a path, please change them to refer to ~/scratch instead.
