== Changes ==


The HPC cluster bwUniCluster 3.0 is the successor of bwUniCluster 2.0. It features accelerated and CPU-only nodes, with the host system of both node types consisting of classic x86 processor architectures.
Changes in hardware, policy and software.
<br>
To ensure that you can use the new system successfully and set up your working environment with ease, the following points should be noted.


== Registration ==
⚫
[[BwUniCluster3.0/Data_Migration_Guide#Summary_of_changes|Summary of Changes]]
All users who already have an entitlement on bwUniCluster 2.0 are authorized to access bwUniCluster 3.0. The user only needs to '''register for the new service''' at https://bwidm.scc.kit.edu .


== Migration ==
== Changes ==


Hardware, software and the operating system have been updated and adapted to the latest standards. We would like to draw your attention in particular to the changes in policy, which must also be taken into account.
How to migrate data from bwUniCluster 2.0 to bwUniCluster 3.0?

Changes to hardware, software and policy can be looked up here: [[BwUniCluster3.0/Data_Migration_Guide#Summary_of_changes|Summary of Changes]]
|}


== Migration ==
bwUniCluster 3.0 features a completely new file system. '''There is no automatic migration of user data!'''
<br>
The file systems of the old system and the login nodes will remain in operation for a period of '''3 months''' after the new system goes live (till July 6, 2025).
<br>
In order to move data that is still needed, user software, and user specific settings from the old HOME directory to the new HOME directory, or to new workspaces, instructions are provided here: [[BwUniCluster3.0/Data_Migration_Guide#Migration_of_Data|Data Migration Guide]]
