I am using Sage Notebook to generate very large files and then process them. The size of the files is tens of Gigabytes but that wouldn't be a problem the way things are set up in my worksheet. However, it seems no matter where the worksheet is stored the associated files are temporarily stored in /tmp whil ethe worksheet is working. For example,
$ ll /raid/istvan/Playground/Sage.sagenb/home/__store__/2/21/212/2123/admin/17/cells/4/
total 8
drwx------ 2 istvan istvan 4096 Sep 4 15:36 ./
drwxrwxr-x 9 istvan istvan 4096 Sep 4 15:34 ../
lrwxrwxrwx 1 istvan istvan 49 Sep 4 15:36 A.mmap -> /tmp/tmpa6CJmh/A.mmap
lrwxrwxrwx 1 istvan istvan 49 Sep 4 15:36 B.mmap -> /tmp/tmpa6CJmh/B.mmap
lrwxrwxrwx 1 istvan istvan 49 Sep 4 15:36 C.mmap -> /tmp/tmpa6CJmh/C.mmap
lrwxrwxrwx 1 istvan istvan 49 Sep 4 15:36 D.mmap -> /tmp/tmpa6CJmh/D.mmap
$ ll /tmp/tmpa6CJmh

The total size of the files is about 110 GB and I have plenty of room on the /raid partition where the Sage Notebook resides, but my / including /tmp partition is way too small for that. How can I make the Notebook NOT to write to /tmp? Is there an envar to set that?
Thanks for any suggestion,
Istvan
