Sharing files on \/scratch<\/h1>\n

History<\/h2>\n

In the past \/scratch<\/span> directories were readable by others by default. Due to increase security requirements for grant funding, this default has been removed.<\/p>\n

We understand some people relied on being able to access other users’ \/scratch<\/span> areas. So we have some methods to return that functionality in a more secure manner, or some possible alternatives to achieve the same goal.<\/p>\n

Guide<\/h2>\n

Preferred sharing methods<\/h3>\n

Option 1: Share with Enterprise Groups<\/h4>\n

You can share (read-only) your scratch directory easily with an enterprise group you belong to, mimicking access to \/projects<\/span>.<\/p>\n

# replace BIO-FAKE-Group with your enterprise group\r\nchgrp BIO-FAKE-Group \/scratch\/$USER\r\nchmod 750 \/scratch\/$USER      # 750: rwxr-x---<\/code><\/pre>\n
You can either use an existing enterprise group or create your own<\/a>.<\/p>\n
Note<\/strong>: Enterprise groups can be members of other enterprise groups, so if you need to share your scratch with multiple groups, you can create a group with the other groups as members without adding each person individually.<\/p>\n<\/div>\n
\n
Option 2: Share with \/common\/contrib or \/projects<\/h4>\n
If you’re sharing research data or data sets amongst your lab or other HPC researchers, you may want to consider using space on either \/common\/contrib<\/span> or \/projects<\/span> instead.<\/p>\n
