From ALICE Documentation
Revision as of 11:59, 6 October 2020 by Deuler
This wiki is the main documentation source for information about the Academic Leiden Interdisciplinary Cluster Environment (ALICE) cluster. ALICE is the research computing facility of the partnership Leiden University and Leiden University Medical Center. It is available to any researcher from both partners. In this wiki, we will introduce the ALICE cluster in detail.
Below you find a collapsible tree structure of our documentation set which gives you a quick overview of the full navigation tree. The root tree items are also directory accessible from the top navigation bar.
This user guide will help you get started if you are new to ALICE and working on an HPC in general.
- More in-depth
- Security and privacy
- More on login nodes
- Using Node802
- Running jobs
- Available software
- Develop your own code
- Running in parallel
- Software packages
- 8 Oct. 2021 - Infiniband network back in operation. The broken Infiniband switch has been replaced and the Infiniband network is working again. You can make use of the Infiniband network again for your jobs on the CPU partitions.
- 8 Oct. 2021 - Node020 and node859 used for testing Node020 and node859 will be reserved from time to time to continue testing the new BeeGFS storage system.
- 30 Aug. 2021 - Node020 reserved to testing We have been working on the configuration of the new BeeGFS storage system. To this purpose, we have reserved node020 for running tests.

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
Leiden University network maintenance on 31 Jul/01 Aug
Maintenance on the network of Leiden University will take place on the weekend of 31 July/01 August.
During this time ALICE will continue to run, but in total isolation, i.e., with no internet access. This means that you will not be able to login to ALICE and jobs cannot for example pull code, download data or access license servers.
We will use this page to provide updates on the status of the cluster.
If you have any question, please contact the ALICE Helpdesk.
