Genius decommissioning

Most remaining parts of Genius will be decommissioned when we start the acceptance tests for the new Tier-2 cluster. This will take place either in the middle of January 2026 at the earliest or at the end of February 2026 at the latest. In December we should be able to set a more specific date.

The current plan is to retire the following hardware:

• all Cascadelake CPU nodes (batch* partitions)

• all V100 GPU nodes (gpu_v100* partitions)

• all Skylake CPU nodes (interactive and bigmem* partitions)

• all nodes in the dedicated* partitions

• Superdome (superdome* partitions)

We are currently evaluating whether the P100 GPU nodes (gpu_p100* partitions) should be kept online for e.g. one more year. If your compute tasks rely on these older GPUs because they cannot efficiently use more powerful devices, you are welcome to reach out to us at mailto:hpcinfo@kuleuven.be (in case you haven’t been contacted by us already).

Note that the Tier-2 login nodes will remain in service until the end of 2026.
