[TOOL_CALLS]Migration du système d'exploitation en Red Hat 9.2
Bonjour,
À l'occasion de la maintenance d'aujourd'hui (4 juin 2024), le système d'exploitation du supercomputer Jean Zay is being updated to Red Hat 9.2 (from 8.6 currently). This update aims to provide a recent software environment on Jean Zay and is part of the preparation framework for the installation of the Jean Zay H100 extension.
This operating system version change should have a limited impact on your use of the machine. Nevertheless, we recommend that you recompile your codes once after the update, even if the majority of them should continue to work without any action on your part.
Please note:
-
The GNU compilers bundled with the operating system have been updated to version 11.3.1. The Intel compilers whose version is lower than 2021 are not compatible anymore with this version of the GNU compilers. The "intel-compilers" modules lower than 2021 will now automatically load the GNU compilers 8.5.0. You can still use another version (lower than 11) by loading it before the Intel compiler, for example "module load gcc/10.1.0 intel-compilers/19.1.3".
-
JupyterHub will still be unavailable for a few hours, it should be back online by the end of the day.
-
The access to the visualization node through a VNC client will be suspended for a few days while we finalize the migration.
-
Due to the deprecation of some encryption algorithms, the access to Jean Zay from some machines using an old SSH version might not be possible anymore (similarly the access from Jean Zay to such machines also might not work).
In case of problems, contact the IDRIS Support.
