  • 2015-06-16:  HCC Tusker Downtime Planned - June 23, 2015
    Category:  Maintenance

    This maintenance outage for software updates affects Tusker only.

    Jobs which cannot complete before June 23rd at 09:00am will be held in queue until the maintenance is complete. We anticipate this work will be finished by 6:00pm the same day.


    To minimize the impact to running jobs we are declaring a downtime for Tusker to complete this work. We will use this maintenance window to update various software components across the cluster. The Tusker login node will also be updated and will require users to log off. Users will be denied access to the Tusker login node until the maintenance is completed.

    Category:  General Announcement

    The Holland Computing Center (HCC) at the University of Nebraska announces an opening for a System Administrator open until filled. For more details please see https://employment.unl.edu/postings/44322 .

    Description of Work:

    Position will be required to maintain HCC core resources including, but not limited to, LDAP and group Content Management System (CMS), provide resolution to user issues, support and maintain user authentication mechanisms and work with HCC staff to maintain systems security integrity. Position will be expected to keep up on industry security announcements and coordinate with other HCC staff to appropriately respond to maintain system security and availability.

    Various tasks including the following will be required: maintaining and upgrading hardware, operating systems, and related aspects (networking, storage, computing) of various systems; performing backups; managing user accounts; installing new software (commercial and public domain); maintaining system security; monitoring system usage; evaluating, recommending and/or negotiating specific hardware purchases. HCC systems are integrated with national computational grids; installation and maintenance of grid protocol software will be required.

    Experience with OpenStack and Linux virtualization technologies is desirable but not required. Supervision, distribution and coordination of tasks for graduate and/or undergraduate students often expected. Position works in cooperation with other University staff and researchers associated with research computing.

Position requires frequent and effective communication of technical, operational and educational information in a variety of formats. Periodic travel between NU campuses (UNO, UNMC, UNL) is required.


    Minimum requirements:

    Bachelor’s degree in computer science or computing intensive physical science OR two years of experience in systems administration of multiple machines. Programming and systems knowledge in LINUX required. Must have high level scripting proficiency (e.g. Bash, Python, Perl).
