Māui major maintenance Q1'23

Māui will undergo a major maintenance outage in the new year. This will see the Cray Linux & Programming Environments on Māui upgraded by two major versions. The outage is expected to last 7-10 days and during this period Māui will be completely unavailable for user compute workloads.

This will bring Māui to a better supported and more secure operating level. Including more up-to-date tooling and libraries, with associated feature and performance benefits. This work will also enable further upgrades to NeSI's shared HPC storage system (which is currently blocked by client constraints on Māui).

Software built on Māui may not work without recompilation after the upgrade. NeSI will be testing key software and libraries from our supported software stack on Māui early in the new year. We will update this announcement as we learn more about the impact, including an outline of expectations and support for Māui users ahead of the outage. If you have any particular concerns about the impact for your work, please reach out to NeSI Support.
