SUNK v6.7.0 has been released with CUDA 12.9 support, enhanced SCIM and nsscache functionality, HDF5 plugin support, and various bug fixes for improved system stability and performance.

​
Overview

​
CUDA 12.9 support

CUDA 12.9 is now supported in the compute node definition.

​
SCIM and nsscache updates

  • SCIM filtering: New configuration options are now available for SCIM user and group filtering, via nsscache.nsscacheConfig.default.scim_users_parameters.
  • Shadow map for SCIM: nsscache for SCIM will now create the shadow map by default.
  • Home directory override: NSSCache now has the ability to override the home directory. This can be set with the following settings based on your authentication method:

​
CronJob scheduling

The default schedule for the nsscache CronJob has been changed to run every minute (* * * * *).

​
HDF5 plugin support

Support for the HDF5 plugin is now included, allowing for advanced data handling capabilities.

​
Bug fixes

  • Directory Service Integration: Enable sudoGroups mounts when nsscache is configured.
  • Correct Gres Type for NVIDIA RTX PRO 6000: Fixed the gres type in the rtxp6000-8x compute definition to ensure proper GPU detection.
  • Slurm Fixes for TaskProlog: Backporting of Slurm fixes to address errors when using TaskProlog.
  • Node Locking Improvements: Continue polling for pod information within the context timeout to prevent errors with node locking.
  • Switch to bitnamilegacy: Switched to bitnamilegacy images for the following resources as per bitnami recommendations:
ImpactDuring upgrades, there may be a moment where MySQL enters an Error state. While the MySQL pod is down, other components that depend on it - such as the Slurm accounting and controller pods - may experience issues coming up. Depending on how long it takes to come back up, it could also trigger a cascading crash. This should resolve once the bitnamilegacy image is pulled. If that process is fast enough, these issues will not be visible.
