All users will need an identikey to obtain an account. Users must first log into the VPN before gaining access to Newton, Bromwich, Cantor, Herschel, Ramanujan, and Riemann when off campus. Please contact the IT Professional at am_itsup@colorado.edu to be added to the notifier group.

Policies

  1. The Newton machine is not to be used for running simulations. Please use Bromwich, Cantor, Herschel, Ramanujan, or Rieman for this purpose.
  2. Users and user data will be removed from the Newton Lab systems one year after they have left the university.
  3. All critical data that is kept on the system should be backed up by the user elsewhere. There is no guarantee regarding backups or restoration of data.
  4. Your home directory is not for storing data and should not exceed 15Gb. Storing more than this amount causes serious performance issues on all machines.
  5. Misuse of the machines will result in an initial warning. If the misuse is repeated, the user will not be allowed to continue using the resource.
  6. Contact am_itsup@colorado.edu to be added to the notifier group so that you can receive messages about the systems status.
  7. Try to limit your usage to two machines at most, as there are several people who use these resources.
