Add/Remove Users (User Authorization)
A principle investigator (PI) may request accounts for additional users on an existing project by using the appropriate online form. The form also can be used to remove users from a project.
- SDSC users with TeraGrid allocations, go to the Add/Remove User Form in the TeraGrid User Portal (Click on My TeraGrid tab after logging in).
- Other SDSC users (without TeraGrid allocation) use the form below.
Your new users will receive their information packets via conventional mail in about two weeks. They must sign and return the User Responsibility Form within 30 days.
Not sure which type of account you have? Enter your project number below. You will be directed to the correct form.
