Gateway The gateway provides a secure method of authenticating over SSH.


From your workstation you can connect to the Gateway, this Gateway will be able to connect to both the Storage as well as the Login node.

ssh-gw.leidenuniv.nl
Login The two login nodes can be used to prepare your work. After setting up your calculations, you can place a calculation request in the queue. 10.161.0.12

10.161.0.13

Data Share The data share node is used to store any research data used to perform your calculation.

Management The management node can be used to retrieve information concerning the HPC. 10.161.0.10
Queue The queue is a mechanism of Slurm, when a job is first in line it is picked up when compute resources are available.
Compute Nodes When the compute nodes are assigned with a job they execute the calculation.


Access

You need two accounts, the first is your Leiden University account that you will use to login to the Gateway, the other is your ALICE account that you will use to login to the ALICE Login node.

Depending on your local system, you can use different tools to connect to ALICE. In all cases you'll need to facilitate port-forwarding and/or tunnels. For a step-by-step guide, please select one of the following:


Having finished this step, you will have access to both the command line and the file system of ALICE. In the next steps we'll explain how to start using ALICE.
