Output

• Desktops: Summarises the amount of Strudel GPU desktops that are currently available.
• Home directory usage: tells you how much quota you have for your home directory, and how much is currently being used.
• Project usage: tells you how much quota you have in both /projects/ and /scratch/ for each project you belong to.
• Project File Counts: generally not applicable on M3, but will show if you have a quota on the number of files your projects can have.

Double Trouble

On the Lustre file system, project folders may appear to be larger than what they actually are.

Our Lustre system is split into a hot pool (consisting of a cache of very high speed disks) and a cold pool (of slower disks). Data is first moved into the hot pool, then automatically migrated over time into the cold pool. A file can exist in both pools at the same time.

Unfortunately the Lustre usage commands counts both hot and cold pool to your usage. This is a limitation on the current version of lustre, which will be fixed in the next major release. Till then, you may get effects like this. Please conact the Help Desk if this affects your quota.
