*'''24 Mar. 2022 - New scratch storage available to all users: ''' We are excited to announce that the new scratch storage on ALICE is available for you to use from now on. It is a BeeGFS-powered parallel file system storage with a total capacity of 370TB. We have created a user directories for all ALICE users on the new scratch storage: <code>/data1/$USER</code> with a link in your home directory</code>/home/$USER/data1</code>. By default, you have a quota of 5TB which can be extended upon request. We ask all users to migrate their data to the new storage and adjust their workflows accordingly. See also the wiki page: [[Data storage|Data Storage]]. We will keep the old scratch storage available for you to use '''until 30 April 2022'''. Then, we will disable access to it and you will have to contact us to gain access. Another two months later, we will start to remove any remaining data on the old scratch storage. Project directories on the old shared scratch have also been set up on the new scratch storage in <code>/data1/projects/</code>, but links in home directories of project team members have not been changed in order to avoid breaking existing workflows. We ask PIs to also start migrating the data in their project directories. After the migration has been completed, we will change links in the home directories of team members. If you have any questions or need assistance for migrating your data and workflow, please do not hesitate to the ALICE helpdesk.
*** Login node 1 is running and the NVIDIA Tesla T4 has been integrated successfully.

*'''09 Mar. 2022 - New short partition amd-short for all users''' So far node802 has been exclusive to researchers of MI. In agreement with the PI of node802, we are making parts of the resources of this node available to all users now. This will be facilitated through a specific partition called "amd-short" that can run jobs up to 4h using up to 64 cores and up to 1TB of memory. Node802 is somewhat different than all other nodes on ALICE which is you should go through the section "[https://wiki.alice.universiteitleiden.nl/index.php?title=Running_jobs_on_ALICE#Important_information_about_partition_amd-short Important information about amd-short]" before you start using the new partition.
*** Slurm version 20.11.7 is now running on ALICE
 
*** EasyBuild 4.4.0 is used for the Intel and AMD branch
 
*** The partitions notebook-gpu, notebook-cpu, playground-cpu, playground-gpu have been removed.
 
*** The time limit on the mem partition has been changed from Infinite to 14 days.
 
*** Resources on the testing partitions are now limited to 15 CPUs per node, a maximum amount of memory per node of 150G, a default memory per cpu of 10G.
 
*'''28 Jun. 2021 - ALICE system maintenance continues tomorrow:''' During our maintenance, we encountered a few issues with the Infiniband switch and login node 01. Because of the issues, we also did not finish updating the GPU nodes. We will continue working on these item tomorrow (Tuesday, 29 June 2021) until at least 12:00.  ALICE will remain offline for maintenance.
 
*'''27 Jun. 2021 - ALICE offline for system maintenance:''' More information here [[News#Next_Maintenance|Next maintenance]].
 
*'''25 Jun. 2021 - System maintenance on ALICE:''' ALICE will undergo system maintenance on '''28 June 2021'''. More information here [[News#Next_Maintenance|Next maintenance]].
 
*'''2 Jun. 2021 - Rclone available on ALICE:''' Rclone is available on ALICE and there are instructions on how to set it up to transfer files to and from SurfDrive and ResearchDrive: [[Data_Transfer |Data transfer to and from ALICE]]. This is a new feature and feedback on your experience is very welcome.
 
*'''29 Apr. 2021 - ALICE User Survey 2021 closed:''' The ALICE User Survey 2021 is closed. We have received responses from 76 users. We are thrilled to have this many contributions.
