Terms of Usage

  1. Data is not backed up. None of the data on the CAC systems is backed up. The data that you keep in your home directory, /nobackup, /tmp or any other filesystem on any of the CAC systems is exposed to immediate and permanent loss at all times. You are responsible for mitigating your own risk. We suggest you store copies of hard-to-reproduce data on systems that are backed up or at least systems other than the CAC systems.
  2. Your usage is tracked and may be used for reports. We track a lot of job data and store it for a long time. We use this data to generate usage reports and look at patterns and trends. We may report this data, including your individual data, to your adviser, department head, dean, or other administrator or supervisor.
  3. Maintaining the overall stability of the system is paramount to us. While we make every effort to ensure that every jobs 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 CAC web site; for unscheduled outages we will announce them as quickly as we can with as much detail as we have on that same website.You can also track the CAC at Twitter name UMCoECAC.
  4. You are responsible for the security of sensitive codes and data.  If you will be storing export-controlled, HIPPA-influenced, or other sensitive or secure software, libraries, or data on the cluster, it is your responsibility that is is secured to the standards set by the most restrictive governing rules.  We cannot reasonably monitor everything that is installed on the cluster, and cannot be responsible for it, leaving the responsibility with you, the end user.
