HPC/HTC Accounts


HPC/HTC accounts are available for all University faculty, staff and students for the purpose of research. All accounts must be sponsored by a University of Arizona Principal Investigator (PI). Sponsorship gives permission to each sponsored user to use the HPC/HTC resource allocations of the sponsor. PI’s can sponsor multiple users. Users can be sponsored by multiple PI’s. HPC/HTC resource allocations are granted to PI’s. Users utilize resources from their sponsor’s allocations.

  • All HPC accounts are for academic purposes only.
  • Commercial activities are prohibited
  • Password sharing and all other forms of account sharing are prohibited
  • Account holders found to be circumventing the system polices and procedures will have their accounts locked or removed

All HPC accounts can be requested through the UA automated account system at http://account.arizona.edu
For questions about HPC account procedures please refer to Requesting and Sponsoring HPC/HTC Accounts or contact HPC Consulting at hpc-consult@list.arizona.edu

Who is Eligible

For both of the two categories of HPC/HTC systems users are required to enroll in NetID+ before using their account. If a user does not have NetID+ login attempts will appear as password failures. To enroll in NetID+, follow the instructions here.

Additional Types of HPC Accounts

  • Sponsoring Accounts

PI’s may sponsor any number of accounts but these accounts must be used for research only. Sponsoring faculty are responsible for all of their sponsored account users. These accounts are subject to periodic review and will be deleted if the sponsoring faculty or the account holders change their University affiliation or fail to comply with UA and HPC IT account policies.  All user accounts will be assigned resources and job priority based on the allocations and priorities of their sponsoring PI.

  • Instructional Accounts

PI’s may sponsor HPC accounts for instructional purposes on the HPC/HTC systems by submitting a proposal to the HPC Consulting team at hpc-consult@list.arizona.edu. This is an oversight review. Proposals are subject to denial only when the proposed use is inappropriate for the systems and/or when the course would require resources that exceed available capacity on the systems or substantially interfere with research computations.  HPC accounts for instructional purposes will be added by the Sponsor into a separate group created with the 'class group' designation.  Class group membership is to be sponsored for one semester and the Sponsor will remove the group at the end of the semester.  Class groups will not receive any standard queue time. All class group jobs will be submitted to the windfall queue.

Account Deletion

Accounts not used for 180 days will be suspended. The files associated with a suspended account will be retained for six months. Data cannot be retrieved after that time.
Accounts for individuals no longer affiliated with the University are removed after the last day to sign up for classes in each new term.
