Scratch Disks

To speed up computations by access to local disks and to minimize the load of the network, most computers at IAAT are equipped with a local scratch disk. This disk can be accessed under the canonical name /scratch. Depending on funding it is planned to equip all of our machines with such a disk. Data on /scratch are solely accessible on the local computer and are not backuped. The /scratch disks are thought for the short-term storage of large amounts of data (e.g., CCD-Frames, lightcurves, intermediate results of computations, input data for computations, etc.), and not for the long-term storage of data or as a place to store private FTP data.

Depending on how long the data are needed, users are requested to generate a subdirectory in /scratch/daily or /scratch/weekly using their own user-id as the name of the directory. Data in these subdirectories is automatically deleted without any warning 24 hours or 7 days after the last access to the data.

The following /scratch-disks are currently available:

 aitos1:  9GB     aitos2:  9GB     aitos3:  9GB
 aitli01: 1GB     aitli02: 3GB     aitli03: 3GB     aitli04: 3GB
 aitxu3:  2GB
