Managing your Accounts

On this page, you will find information to help you manage your allocation of computing time. 

Responsibilities of Principal Investigators

In addition to following the policies laid out for all PSC users, PIs are responsible for adding all members of the research team to an account, and for renewing accounts when necessary.

Adding users to an account

Each member of your research team should be provided with their own individual account. Such accounts charge against the PI's research grant. The PI's billing statements will show the usage and charges incurred by each account under the grant, providing additional administrative control. With each research team member documented, papers published under the name of any member of the team will be readily attributable to the PI's research project and PSC allocation.

Additional user accounts must be authorized by the PI. To add a user, the PI must complete an online form.

If you are renewing an allocation, keep in mind that all active users are automatically reactivated when the allocation is renewed.

Applicable forms

  • Information and the form to add users to an NSF Cyberinfrastructure allocation is online from the XSEDE web site.

Renewing your allocation

All allocations except Coursework Allocations are for a one-year period and are renewable annually.   The duration of a Coursework Allocation is specified when the allocation is awarded.

Service Units unused at the allocation expiration or renewal date are forfeited.

All active users are reauthorized when an allocation is renewed.

PSC requests that a copy of any publications (preprints or reprints) resulting from reseach done on PSC systems be sent to the PSC Allocation Coordinator. All publications resulting from work done on a PSC allocation should include an acknowledgement.

Renewing an NSF Cyberinfrastructure Allocation
