The new Euler IV nodes will be available for beta testing soon. They have 36 cores and 192 GB of memory. In a first phase, selected beta testing users will get access to the new nodes. Later, there will be an open beta testing phase where all Euler users can submit jobs to the new nodes before the finally go into production.

Select or avoid Euler IV nodes

You can force or prevent your jobs from running there. To force your job to run on these nodes, request the “-R beta” bsub option:

bsub -R beta [other bsub options] ./my_command

To prevent your job from running on these nodes, request the “-R stable” bsub option:

bsub -R stable [other bsub options] ./my_command

If you encounter any problem with running your jobs on the new Euler IV nodes, then please report it to cluster support.
