The LSSC0 cluster and its resources will be retired on April 30, 2026.
HPC@UCD is getting toward the end of migrating users, hardware, and data from LSSC0 to Hive. Labs with login or GPU nodes under seven years of age have been migrated to Hive according to our hardware policy at https://hpc.ucdavis.edu/model-hpc-hardware-support.
Please ensure that the software currently used by your team on LSSC0 is available on Hive. If you need specific software, please let us know by requesting it using the Software Request Form at https://hpc.ucdavis.edu/software-installation-policy .
PIs are first required to make an account on Hive by going to the High-Performance Personnel Onboarding Portal at https://hippo.ucdavis.edu, selecting Hive as their cluster, and entering the "New PI Onboarding (sponsors)" group. HPC@UCD staff will approve the request, and the new PI group will be available for users to select. Please see associated documentation: https://docs.hpc.ucdavis.edu/general/account-requests/#if-you-are-a-pi-and-have-bought-or-are-planning-to-purchase-resources
Once the PI group has been created, users are required to make an account on Hive by going to the High-Performance Personnel Onboarding Portal at https://hippo.ucdavis.edu, selecting Hive as their cluster, and selecting their PI/lab’s group. The PI will receive an email with a link to approve the request. Once it is approved, the user will be added to the PI's group and will be able to log in to Hive. Documentation here: https://docs.hpc.ucdavis.edu/general/account-requests/#if-you-are-a-pi-and-have-bought-or-are-planning-to-purchase-resources
Users are responsible for migrating their home directory to Hive. We have helpful instructions for those users who need assistance with rsync at https://docs.hpc.ucdavis.edu/hive/lssc0-data-migration/
The lab share data migration takes place over several steps:
- HPC staff will copy group data from LSSC0 to Hive during an initial pass.
- PIs will be notified via ServiceNow email to stop jobs in preparation for a second pass of data and to arrange for the final transition to Hive. ServiceNow allows HPC staff to keep PI’s notified and the status tracked.
- It is the PI’s responsibility to ensure all of their active LSSC0 users create accounts on Hive. Users who have not made accounts on Hive will have their group data owned by the PI, as we will not be able to do an accurate mapping.
- Login nodes under seven years of age will be migrated to Hive, and groups will be provisioned with like resources. Login nodes over seven years of age will be decommissioned.
- HPC staff will perform a final data copy and adjust permissions to make the Hive data accessible. The data on LSSC0 will be marked read-only.
