 This page records major changes to Hábrók, which are mostly carried out during scheduled maintenance periods. This changelog is kept since August 13th 2025, although changes have been made during past scheduled maintenance periods and on-demand as necessary.
-===== 2025-08-28 ====
+===== 2025-09-18 =====
+  * The maintenance for 15 September had to be extended because of a vulnerability in the Linux kernel, which needed to be patched urgently. In order to patch the issue more quickly we changed from Rocky Linux to Alma Linux on the compute and user interface nodes. Since both Linux distributions are derived from the same release of Redhat Enterprise Linux this does not affect any other installed software.
+  * The Lmod package for the module system needed to be downgraded as the latest release introduced issues, causing the module system to fail.
+  * We've equipped 24 regular nodes with an Cornelis Networks Omnipath adapter and migrated those to the parallel partition as "omni" nodes. We've extended the ''regularshort'' and ''regularmedium'' partition to share nodes with the ''parallel'' partitions. This extends the available capacity for jobs running over more than one node, that require a fast, low-latency interconnect.
+===== 2025-08-28 =====
   * A new node with 2 NVIDIA L40S GPUs has been added to the gpushort partition. The node was procured by the Computer-Aided Organic Synthesis group and their dedicated "caos" partitions have a higher priority than gpushort.
