Planned Maintenance:

Planned shutdowns are usually reserved for the first full week of the second month of each calendar quarter to carry out system maintenance, skipping partial weeks within any given month and avoiding end of semester deadlines where possible, with exceptions as noted below. These can sometimes be skipped if not needed, expanded if necessary, or reduced. In addition, there will sometimes be necessary special planned shutdowns to carry out upgrades or alterations to the clusters.

For Academic Year 2024-2025, the planned shutdowns will be on the following schedule:

1) October 7-11, 2024 (Completed early) *
2) February 3-7, 2025 (Complete)
3) May 19-23, 2025 (delayed to avoid finals) (UPDATE: shortened to May 19-21, 2025)
4) August 4-8, 2025

* Shutdown may continue for an extended time for the quanah partition after return to service of the rest of the cluster. When the quanah partition returns to service, it will be reconfigured with a new operating system version and all new software modules. Those using the quanah partition should plan on recompiling or reinstalling their code.
 
We appreciate your patience during these maintenance periods, which are used to improve operation and stability of the resources and to implement new features as available. Please feel free to contact us at hpccsupport@ttu.edu if you require assistance or have any further questions.

Maintenance downtime policy for HPCC systems:

• Special periods may be reserved for performing routine maintenance. Users will be notified as early as possible when we are planning on bring the systems down for any reason.
• Systems may also go down at anytime to fix security issues, but every effort will be made to give the earliest possible notice.
• Maintenance may also be required without prior notice in the event of system crashes or any unstable behavior.

Users should always keep extra copies of any files that are critical to their research on systems that are outside of the HPCC to plan around system maintenance and to guard against possible loss in the event of unforeseen catastrophic failure.

This policy is just good general practice and applies to all critical research files, regardless of where they are stored or whether or not they are located on HPCC resources.

For further information, see the "Data Transfer" and "Data Policy" guides on this web site.
