Migration of the operating system to Red Hat 9.6
This page was translated by an AI (LLM) with a cursory human check and is awaiting full review.
Hello,
During yesterday's maintenance (February 17th, 2026), the operating system of the Jean Zay supercomputer has been updated to Red Hat 9.6 (from 9.4 previously). This update aims at keeping a recent software environment available on Jean Zay.
This operating system version change should have a limited impact on your use of the machine. The majority of your executables should continue to work without any action on your part, however in case of issues we recommend that you try to recompile your codes.
The GNU compilers bundled with the operating system have been updated to version 11.5.0. The "gcc/11.4.1" module is now an alias for a new "gcc/11.5.0" module in order to ensure an easy transition.
In case of problems, contact the IDRIS support.
Best regards, The IDRIS user support team
