Armis2 Frequently Asked Questions

1. What is Armis2?

Armis2 is an ARC-TS managed HPC cluster available for researchers who work with Protected Health Information (HIPAA).  All computational work is scheduled via the Slurm resource manager and task scheduler, while data is kept on Turbo Research Storage. To request an allocation please contact HPC support.

2. Who can use Armis2?

Armis2 is available for researchers at the University of Michigan who require HIPAA-compliant high performance computing.  If you do not work with HIPAA data, your needs may be met by other ARC-TS services (i.e. Great Lakes or Lighthouse).

3. What forms do I need to fill out?

  1. The Principal Investigator (PI) needs to request a Slurm account, specifying users that can access the account and payment details.
  2. Each user given access to the account must request a user login.  Please refer to the Armis2 User Guide for additional steps and usage information.

4. How much does Armis2 cost?

Currently, there is no charge for using Armis2.  Armis2 has an on-demand job model, paying for the resources your job uses, and there will be a rate applied on January 6th, 2020. For current prices, see the HPC rates page.

5. As a PI, how can I limit usage on my account?

Principal Investigators can request that CPU, GPU, memory, billing units, and walltime be limited per user or group of users on their account.  For more information, see the Armis2 policy documentation.

Limits must be requested by emailing HPC support.

6. How can I get a trial account on Armis2?

If you are a PI that hasn’t used Armis2 before, you are eligible for a limited trial account.  This account will have $150 worth of cluster time (see the rates page) and will be unable to run jobs after 1 month.  If interested, please contact HPC support specifying that you’d like a trial account with lists of users and admins.

Users need to request a user login to access the cluster. All users must have been granted access to an account before a user login can be created. Be sure to have a shortcode that you are authorized to use, a list of uniqnames of the users who should be able to use the account. a list of uniqnames of the administrators who are authorized to make changes to the account. If you had a pilot account, you can optionally use the same administrative group, the school or college you are a part of, and any limits that you want to set on the account (such as a spending limit or resources usage limits).

If you have questions about gaining access to an account (or getting a trial account), please email
