A Note About Quotas

The welcome message you receive upon successful login to Stampede2 has useful information for you to keep track of. Especially of note is the breakdown of disk quotas for your account, as you can keep an eye on whether your usage is nearing the determined limit.

Once your usage is nearing the quota, you’ll start to experience issues that will not only impact your own work, but also impact the system for others. For example, if you’re nearing your quota in $WORK, and your job is repeatedly trying (and failing) to write to $WORK, you will stress that file system.

Another useful way to monitor your disk quotas (and TACC project balances) at any time is to execute:

login1$ /usr/local/etc/taccinfo # Generally more current than balances displayed on the portals.
