Genius hardware¶
Genius is KU Leuven/UHasselt’s most recent Tier-2 cluster. It has thin nodes, large memory nodes, as well as GPGPU nodes.
Login infrastructure¶
Direct login using SSH is possible to all login infrastructure without restrictions.
You can access Genius through: login-genius.hpc.kuleuven.be
This will loadbalance your connection to one of the 4 Genius login nodes. Two types of login nodes are available:
- classic login nodes, i.e., terminal SSH access:
login1-tier2.hpc.kuleuven.be
login2-tier2.hpc.kuleuven.be
login3-tier2.hpc.kuleuven.be
login4-tier2.hpc.kuleuven.be
- login node that provides a desktop environment that can be used for,
e.g., visualization, see the NX clients section:
nx.hpc.kuleuven.be
Warning
This node should not be accessed using terminal SSH, it serves only as a gateway to the actual login nodes your NX sessions will be running on.
The NX login node will start a session on a login node that has a GPU, i.e., either
login3-tier2.hpc.kuleuven.be
login4-tier2.hpc.kuleuven.be
