RedHat EL 9 Now Default in All Partitions
The new major release of the cluster's operating system is now the default
2025/10/16
Since 2025-10-16, no “special” partitions for RHEL9 any longer--the queues have been converted and job scheduling has recommenced.
The switch-over is over and finished--from today, RHEL 9 is the default for all partitions.
This always implicates the switch to the new module system (based on SPACK).
For all jobs compatible with RHEL 9 to be submitted as of now, remove any
#SBATCH --partition special_rhel9…
line from your job scripts.
In case RHEL 8 is still needed
Instead, you need to specify a special partition if you still need RHEL 8:
#SBATCH -p special_rhel8
for general (MPI) jobs (ca. 128 compute nodes), and#SBATCH -p special_nvd_rhel8
for GPU jobs (2 accelerator nodes with NVidia A100 GPUs).
To submit jobs into these special partitions, we recommend to use the following login nodes for submission:
Login Nodes under RHEL 8
The two login nodes remaining on RHEL 8 are:
lcluster7.hrz.tu-darmstadt.de (LB2A2, 104 CPU cores)lcluster19.hrz.tu-darmstadt.de (LB2A1, 96 CPU cores)
