  • 12 Jan. 2022 - X2Go available on ALICE: We have added a new option to connect to ALICE. With X2Go, it is possible to work on ALICE using a graphical desktop environment. You can find details on how to set it up here: Login to ALICE using X2Go
  • 11 Jan. 2022 - Early Access phase for new storage system: As part of the commissioning of ALICE's new 370TB BeeGFS-powered storage system, we have started the Early Access phase. In this phase, we give a limited number of users access to the new storage system to try it out and provide feedback to us. This way, we can test and evaluate the performance of the new storage system under more realistic conditions with various kinds of workloads. Our goal is to conclude the Early Access phase at the end of January. We have still spots left for participating in the Early Access phase. If you are interested, please contact the ALICE helpdesk with a short description of the jobs that you are running and how much storage you need.

Maintenance

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

Leiden University network maintenance on 20/21 November

Maintenance on the network of Leiden University will take place on the weekend of 20/21 November. The official announcement from the University can be found on the University webpage.

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.

  • Copying data to the shared scratch via sftp:
    • There is currently an issue on the sftp gateway which does prevents users from copying data to their shared scratch directory, i.e., /home/<username>/data
    • A current work-around is to use scp or sftp via the ssh gateway and the login nodes.
