CLAIX-2018 dialog systems
Due to the high load on the login / dialog nodes affecting their usability, we decided to reduce the maximum usable cores on each login node to four cores for each user. Please note: These login nodes should be used for programming, preparation and minimal post processing of batch jobs. They are not intended for production runs or performance tests. For longer tests (max. 25 minutes), parallel debugging, compiling, etc., you can use our „devel“ partition by adding „#SBATCH –partition=devel“ to batch jobs or interactively with „salloc -p devel“.
For all productive jobs, please use our batch system **without** „#SBATCH –partition=devel“. If you want to more learn more about the batch system, we invite you to our Slurm introduction.

HPC Cluster: Linux Kernel Upgrade
The Linux Kernel on the CLAIX18 compute nodes is being upgraded to kernel version 4.18.0-477.21.1. To maximise the availability of the compute cluster, the mandatory reboot of the nodes is scheduled as a reboot job, thus allowing all already submitted and running jobs for completion before the upgrade takes place.
Please note that the reboot is prioritised over other jobs, and some nodes may be temporarily unavailable after the reboot.
Best regards,
Your HPC-Team@RWTH

Change in SSH Configuration: Depreciation of Insecure Methods, Addition of New Methods
As the result of a recent security evaluation, we have decided to disable several methods in key exchange, message authentication codes and encryption ciphers classified insecure/weak which obsoletes the following methods and method groups as listed below. In general, we have disabled SHA-1-based methods since SHA-1 is broken since early 2017 (cf. Stevens et al.: „The first collision for Full SHA-1“).
We kindly ask you to update your client configuration accordingly since these methods cannot be used anymore to access the RWTH Aachen HPC Cluster until further notice: Weiterlesen »
