Off to research computing Wonderland

ALICE is the computing facility for excellent research of Leiden University. With ALICE you have the world of computing at your fingertips. On this wiki, you can find the information you'll need to get started and become more skilled in using computing to support your research.

For background information, read the About ALICE page.

Please know that this wiki is currently a work in process. We appreciate any questions or comments on the contents so that we can improve the range of information that we supply here.

IMPORTANT NOTE: ALICE is still in a build-up phase. Configurations are still subject to change. You may, therefore, experience unexpected behaviour for the time being.

Use of the ALICE cluster must be acknowledged in any and all publications. For more info see: About ALICE


This section is used to announce upcoming maintenance and provide information before, during and after it. For general information about our maintenance policy, please have a look here: To maintenance policy

Next Maintenance

The next maintenance window will take place on 01 Feb. 2020.

Our main goals for this maintenance window are

  • to update the license of the Bright Cluster Manager software
  • to integrate a new high-memory node bought by a research group from the Mathematical Institute. For now, this node will be exclusively available to the members of the reserach group.

Important: The planned work should not have any impact on your usage of the cluster. You will be able to work with the cluster without any interruptions.

Getting Started

If you're new to ALICE, please check out the Getting Started page.

Gaining access

Access to the cluster and file transfer are done via SSH and SCP/SFTP. Select one of the below links for more detail or click on the heading of the paragraph for a full overview.

Access Policy

Access needs to be granted actively (by the creation of an account on the cluster by the ALICE Cluster workgroup. Use of resources is limited by the scheduler. Depending on the availability of queues ('partitions') granted to a user, priority to the system's resources is regulated on the basis of Faculty/institute/PI levels.


Cluster Monitoring Software and Scheduler

ALICE uses Bright Cluster Manager software for overall cluster management and Slurm as the scheduler.
