As part of the University's efforts to identify and mitigate risk to its networks and computing systems, potential issues with Caviness have been identified.  It is necessary that we address those issues to balance risks versus users' ongoing access to and functionality of the cluster.  The mitigations include:

    - Caviness will be moved into a different network to isolate it from other campus computing systems

    - Augment SSH username/password authentication with multi-factor authentication (MFA)

    - HPC accounts for UD users will no longer synchronize with UDelNet passwords

Each is discussed in more detail on the HPC Wiki at:

IT-RCI staff will be holding a town hall-style meeting from NOON to 1 P.M. on WEDNESDAY, NOVEMBER 5, in the Faculty Commons (116 Pearson Hall).  All in the Caviness community are invited to attend to discuss how these changes could affect work being done on the cluster.

    - IF YOU PLAN TO ATTEND, please email it-rci-info@udel.edu to let us know.

    - IF YOU CANNOT ATTEND AT THAT TIME but have concerns, please email it-rci-info@udel.edu so IT-RCI can include you in any follow-up meetings that are scheduled.

IT-RCI staff thank the community for their understanding as we work to better-secure the clusters and protect their access and their research computing resources.
