Armis Terms of Usage

  1. Limited data restoration. The data in your home directory can be restored from snapshots going back 3 days..  Anything beyond 3 days can not be retrieved.  Data stored on outside your home directory such as a group share will be subject to other data-lifetime policies that is setup at the time of purchasing the respective Turbo NFS volume.. You are responsible for mitigating your own risk. We suggest you store copies of hard-to-reproduce data in your home directory or on HIPAA-aligned storage you own or purchased from Turbo.
  2. System usage is tracked and is used for billing reports and capacity planning. Job metadata (example: walltime, resource utilization, software accessed) is stored and used to generate usage reports and to analyze patterns and trends. ARC-TS may report this metadata, including your individual metadata data, to your adviser, department head, dean, or other administrator or supervisor for billing or capacity planning purposes.
  3. Maintaining the overall stability of the system is paramount to us. While we make every effort to ensure that every job completes with the most efficient and accurate way possible, the good of the whole is more important to us than the good of an individual. This may affect you, but mostly we hope it benefits you. System availability is based on our best efforts. We are staffed to provide support during normal business hours. We try very hard to provide support as broadly as possible, but cannot guarantee support on a 24 hour per day basis. Additionally, we perform system maintenance on a periodic basis, driven by the availability of software updates, staffing availability, and input from the user community. We do our best to schedule around your needs, but there will be times when the system is unavailable. For scheduled outages, we will announce them at least one month in advance on the ARC-TS home page; for unscheduled outages we will announce them as quickly as we can with as much detail as we have on that same page.You can also track ARC-TS at Twitter name @ARCTS_UM.
  4. Armis is intended only for non-commercial, academic research and instruction. Commercial use of some of the software on Armis is prohibited by software licensing terms. Prohibited uses include product development or validation, software use supporting any service for which a fee is charged, and, in some cases, research involving proprietary data that will not be made available publicly regardless whether the research is published . Please contact if you have any questions about this policy, or about whether your work may violate these terms.
  5. Data subject to export control and HIPAA regulations may be stored or processed on the cluster. The appropriate storage solution for storing export controlled information or PHI that can be accessed on the Armis cluster is the  Turbo-NFSv4 with Kerberos offering(See the Sensitive Data Restrictions for Turbo-NFSv4 with Kerberos for further details). It is your responsibility, not ARC’s, to be aware of and comply with all applicable laws, regulations, and universities policies (e.g., ITAR, EAR, HIPAA) as part of any research activity that may raise compliance issues under those laws. For assistance with export controlled research, contact the U-M Export Control Officer at For assistance with HIPAA-related computational research, contact the ARC liaison to the Medical School at
