Temporary Files and Using the Home Directory
Many software packages create and manipulate temporary files during the execution of the program. These temporary files are commonly placed within your Home directory by default. You must remain aware of how much quota space is left within your Home directory at all times. If your Home directory is filled, attempts to write or modify temporary files will fail.
This may cause your jobs to terminate (be killed) or hang (do nothing, waste SUs).
The easiest way to avoid this issue is to store your files within your Scratch directory. Use cd $SCRATCH to navigate to your Scratch directory.
showquota will allow you to view your quota limits.
