# July 11, 2025 - SUNK v6.6.0 release

> SUNK v6.6.0 introduces SCIM provisioning, dashboard links, improved node reconciliation, and new GPU definitions

SUNK v6.6.0 has been released with SCIM provisioning support, enhanced monitoring capabilities, improved node management, new compute definitions, and various infrastructure improvements.

## Overview

SUNK v6.6.0 introduces SCIM provisioning via `nsscache`, enhanced monitoring with dashboard links, improved node reconciliation, new GPU compute definitions, metrics fixes, segment-calc script improvements, and base image upgrades.

## Key changes

### SCIM provisioning via `nsscache`

SCIM provisioning for SUNK is now available via `nsscache`, enabling automated user and group management from your Identity Provider (IdP) to CoreWeave clusters.

#### Configuration requirements

The SCIM suggested settings can be found in the slurm chart `values-cw.yaml` at `nsscache.nsscacheConfig`.

**Required changes from current defaults in the `values.yaml` files:**

1. **`nsscache` does not use SSSD and it is best set to `false`:**
   * In the Slurm chart: `sssdContainer.enabled: false`
   * In the Slurm-login chart: Change to `directoryCache.source: nsscache`

2. **Requires `nsscache.existingSecret` to be present with auth token in it:**
   * `nsscache-scim-auth-token` key inside the secret with the token

### Dashboard links in SLURM output

Added ability for dashboard links to be added to SLURM output, providing direct access to monitoring dashboards for jobs and nodes.

### Improved node reconciliation

Enhanced reconcile logic for nodes that are in a Reservation, improving cluster stability and resource management.

### New compute definitions

Added new GPU compute definitions:

* **`rtxp6000-8x`**: [NVIDIA RTX Pro 6000](/platform/instances/gpu/rtxp6000-8x) Blackwell Server Edition

### Metrics improvements

* **Fixed adding `slurm_cluster` label on VMPodScrape Metrics**: Resolved label consistency issues
* **Added scraping of MySQL metrics via VMPodScrape**: Enhanced monitoring coverage for database components

### Segment-calc script improvements

Improved segment-calc script for visualizing block scheduling, providing better insights into cluster resource allocation and utilization patterns.

### Base image upgrades

Upgraded nccl-test base images for improved performance and compatibility with the latest NVIDIA software stack.

## Configuration changes

### SCIM setup

To enable SCIM provisioning, follow the instructions outlined on the [Provision users in SUNK page](/products/sunk/manage_sunk/manage_cluster_access/sunk_user_provisioning).

### Compute definitions

The new compute definitions are automatically available and can be used in job submissions and node configurations.

## Migration notes

Existing SUNK deployments will continue to work, but you may want to:

1. Review your SSSD configuration if you plan to use SCIM provisioning
2. Test the new compute definitions in a non-production environment
3. Update any custom monitoring configurations to take advantage of the new metrics
4. Verify your SCIM configuration with the new nsscache integration
