  • 2012-10-26:  Module change on Wednesday, 10/31
    Category:  General Announcement

    Dear HCC user community,

    The following will affect those of you who use the utility "module". Otherwise, please forgive the interruption.

    As announced earlier this month, in an effort to improve our service and stability, we will be simplifying certain modules by dropping minor revisions in their name. This transition is being performed in several steps. The contracted set of modules has coexisted with the explicitly named set for the last several weeks.

    As of Wednesday, 10/31 (yes, Halloween) only the contracted set will be supported, although pre-existing modules will be moved to a 'deprecated' area that you can access using the command

    module load deprecated

    Deprecated modules will be maintained for at least a month, and then subject to deletion. We will be more assertive in the future in keeping our software up to date. As this happens we will move older module versions to the deprecated group in anticipation of their ultimate removal from our systems. Please let us know if you have questions or concerns.

    Thank you.
    David Swanson

  • 2012-10-25:  SANDHILLS: Outage planned for SANDHILLS Wednesday, October 31
    Category:  Maintenance

    On Wednesday October 31 SANDHILLS will be shutdown at
    about 10:00 a.m. in order to upgrade filesystems. Because
    of the nature of the upgrade all running jobs will be killed.

    which cannot complete before the maintenance window will be
    held until work is complete.
