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 and education.

We appreciate any questions or comments on the content of the documentation so that we can improve the range of information that we supply here.

Latest News

  • 01 Aug 2022 - ALICE system maintenance on 22 Aug 2022 - First announcement: We will perform system maintenance on ALICE on 22 Aug 2022 between 09:00 and 18:00 CEST. Our primary focus will be the high-availability set up of ALICE in addition to other maintenance tasks. This will require us to take all compute and login nodes of the cluster offline. It will not be possible to run any jobs and access data on ALICE. Until maintenance starts, you can continue to use ALICE as usual and submit jobs. Slurm will also continue to run your job if the requested running time will allow it to finish before the maintenance starts. If you have any questions, please contact the ALICE Helpdesk.
  • 01 Jun 2022 - Disabled access to old scratch storage: As previously announced, we have disabled access to the old scratch storage. We will keep the data available until 30 June 2022. Afterwards, we will start to delete data so that we can repurpose the storage within ALICE. You can request temporary access by contacting the ALICE Helpdesk. See also the wiki page: Data Storage.

System Maintenance on ALICE will take place on 22 Aug 2022 between 09:00 and 18:00 CEST (See the Maintenance Announcement)
