Login Nodes

The login nodes provide the interface with which to interact with the ALICE system. They consist of 4 HPE servers, each with:

2 x AMD EPYC 7532 32-Core processors
256 GB memory
800 GB local NVMe disk
10 gb ethernet connection to the UoL network
HDR-100 infiniband connection to the ALICE cluster interconnect and storage.

Users connect to the login nodes using ssh for command line access or NoMachine for virtual desktop access.

Console access — Console (left) and Virtual Dekstop (right) access to ALICE login nodes.

NX access — Console (left) and Virtual Dekstop (right) access to ALICE login nodes.

The login nodes provide access to the ALICE shared filesystems (/home, /data, /scratch) and allow users to run basic applications, analyse data and submit computationally expensive simulations/applications to the cluster scheduler to be run on the cluster compute nodes..
