Permitted Usage:

The University at Buffalo's Center for Computational Research maintains servers, clusters, and websites designed for UB's faculty and staff researchers, their students and external collaborators, and industry partners.  All users of CCR systems are required to comply with ALL of the University at Buffalo's Information Technology Policies as well as all CCR policies both explicitly stated here as well as implicitly.  In other words, just because you CAN do something, doesn't mean you SHOULD do it.  


Please see the University at Buffalo's Computer and Network Use Policy for specific information that applies to all CCR resources



Every time you login to a CCR server, you are presented with the following login banner which states our use policy.  If you do not agree with it, you are required to log off immediately:


You are accessing a University at Buffalo (UB) - Center for Computational Research (CCR) computer system that is provided for CCR-authorized users only.  By using this system (which consists of any device attached to this machine, including compute nodes, remote visualization software and hardware, storage and database resources), you have implicitly agreed to abide by the highest standards of responsibility to your colleagues -- the students, faculty, staff, and external users who share this environment.  You are required to comply with ALL University at Buffalo policies (http://www.buffalo.edu/ubit/policies/it-policies-a-to-z/computer-and-network-use.html),as well as state and federal laws concerning appropriate use of information technology.

- CCR is not responsible for the loss or misuse of data on our systems.

- CCR systems are NOT HIPAA-compliant.  Storage of any personally identifiable Protected Health Information (PHI) on our systems is a violation of the Health Insurance Portability and Accountability Act (HIPAA) of 1996 Privacy and Security Rules.  If in doubt, contact CCR before transferring your data.

- All CCR systems are monitored for administrative and security reasons. Use of this system constitutes consent to this monitoring for these purposes.

By continuing to use this system you indicate your awareness of and consent to these terms and conditions of use.  Non-compliance of these terms is considered a breach of University policy and may result in disciplinary and/or legal action.

LOG OFF IMMEDIATELY if you do not agree to the conditions stated in this warning.




Misuse of Systems and Abuse of Account:

We reserve the right to disable any account, without prior notice, that is causing problems internally, externally or violating the University at Buffalo’s information technology policies, CCR policies, and/or the laws of New York State or the United States of America.  Users committing such offenses may be reported to the University at Buffalo's IT security officer or the local authorities.


The #1 policy at UB and CCR regarding computer accounts is that they are NOT TO BE SHARED with anyone.  There is no reason whatsoever to share your password, authentication credentials or SSH keys with anyone.  Doing so will result in your CCR account being deactivated and your actions being reported to the University at Buffalo's IT security officer.  We offer project storage space for groups to securely share data and can work with your group to support this collaboration.  Do NOT share your account with anyone.


Fairshare system for batch job scheduling - The clusters' batch queuing system is designed to give everyone a fair shot at the highest level of throughput for their jobs.  Attempting to circumvent the queue or fairshare system (i.e. cut to the front of the line) is strictly prohibited and will result in your account being deactivated and potential disciplinary action by the University at Buffalo IT security office.  There are appropriate ways to boost your job's priority - see this article for how to become a CCR supporter


Subverting the Scratch Scrubber Policy - CCR provides free, high throughput scratch storage space for use when running your jobs.  Users can create themselves a quota-free directory in /gpfs/scratch.  However, this is TEMPORARY storage space and users are expected to move their data from /gpfs/scratch to their home or project directory when their job is complete.  Any data over 30 days old is deleted automatically nightly.  Any efforts to modify file dates to purposely subvert this policy are prohibited.  We have sophisticated scripts that monitor for attempts to subvert the system.  Users violating this policy risk ALL of their data in /gpfs/scratch being deleted without notice and account deactivation.   



Violatation of CCR policies is a violation of UB Computing and Use policies.  Offenders can be referred to the University at Buffalo's IT security office for disciplinary procedures.
