Chameleon User Terms and Conditions 1.00

Acceptable Use Policy

Chameleon resources are deployed, configured, and operated by the University of Chicago and the Texas Advanced Computing Center (TACC) to serve a large research community. It is important that all users are aware of and abide by this Acceptable Use Policy. Failure to do so may result in suspension or cancellation of the project and associated allocation and closure of all associated logins. Illegal transgressions will be addressed through the University of Texas at Austin (UT-Austin), the University of Chicago, and/or legal authorities.


Users agree to abide by the following policies. Failure to do so will lead to disciplinary actions described in the next section.

All Users
  • Sharing of User Credentials is strictly prohibited.
  • Computing resources may only be used to perform research work consistent with the project’s goals and may not be used for commercial purposes, financial gain, personal gain, any unlawful purpose, or in a way that makes the work of other users difficult.

  • Never infringe upon someone else's copyright. It is a violation of policy and federal law to participate in copyright infringement.
