+# Thor Logical Clusters
+
+This document describes the logical Thor cluster feature, which allows you to define a single logical Thor configuration that gets expanded into multiple physical Thor instances.
+
+## Problem Statement
+
+Previously, to create multiple Thor targets that share a common queue (using auxQueues), you needed to:
+
+1. Define multiple Thor configurations manually
+2. Manually calculate and divide maxJobs and maxGraphs between instances
+3. Ensure each instance had the same configuration except for limits
+
+This was error-prone and required conscious configuration steps to subdivide the total resources.
+
+## Solution: Logical Clusters
+
+The logical cluster feature allows you to define a single Thor configuration that automatically expands into multiple physical instances with properly divided limits.
+
+## Configuration
+
+### Basic Example
+
+```yaml
+thor:
+- name: thorcluster
+  cluster:
+    instances: 3
+    instanceTemplate: "{name}-az{instance}"
+  numWorkers: 2
+  maxJobs: 6      # Will be divided: 2 per instance
+  maxGraphs: 3    # Will be divided: 1 per instance
+```
+
+This configuration will generate:
+- `thorcluster-az1` with maxJobs=2, maxGraphs=1, auxQueues=[thorcluster]
+- `thorcluster-az2` with maxJobs=2, maxGraphs=1, auxQueues=[thorcluster]  
+- `thorcluster-az3` with maxJobs=2, maxGraphs=1, auxQueues=[thorcluster]
+- A logical queue named `thorcluster` that routes to all instances
+
+### Configuration Options
+
+#### cluster.instances (required)
+- Type: integer
+- Minimum: 2
+- Description: Number of physical Thor instances to create
+
+#### cluster.instanceTemplate (optional)
+- Type: string
+- Default: "{name}-{instance}"
+- Description: Template for generating instance names
+- Placeholders:
+  - `{name}`: Replaced with the logical cluster name
+  - `{instance}`: Replaced with instance number (1, 2, 3, ...)
+
+### Validation Rules
+
+1. **maxJobs** and **maxGraphs** must be evenly divisible by the number of instances
+2. All other configuration (numWorkers, resources, etc.) is copied to each instance
+3. Instance names must not conflict with existing Thor names
+4. The `cluster` configuration is removed from generated instances
+
+## Use Cases
+
+### Multi-AZ Deployment
+```yaml
+thor:
+- name: thor-prod
+  cluster:
+    instances: 3
+    instanceTemplate: "{name}-az{instance}"
+  numWorkers: 4
+  maxJobs: 12
+  maxGraphs: 6
+  # Each instance gets maxJobs=4, maxGraphs=2
+```
+
+### Custom Instance Naming with Regions
+```yaml
+thor:
+- name: thor-global
+  cluster:
+    instances: 4
+    instanceTemplate: "thor-region-{instance}-cluster"
+  maxJobs: 16
+  maxGraphs: 8
+  # Generates: thor-region-1-cluster, thor-region-2-cluster, 
+  #           thor-region-3-cluster, thor-region-4-cluster
+  # This pattern is useful when instances need specific naming for
+  # integration with external systems or monitoring tools
+```
+
+## Generated Queue Configuration
+
+When a logical cluster is expanded:
+
+1. Each physical instance gets its own individual queue
+2. Each instance is configured with `auxQueues: [<logical-name>]`
+3. An auxiliary queue with the logical cluster name is created
+4. Jobs submitted to the logical queue are distributed among all instances
+
+## Backward Compatibility
+
+The logical cluster feature is fully backward compatible:
+- Existing Thor configurations continue to work unchanged
+- Existing auxQueues configurations work as before
+- No changes to existing templates or configurations are required
+
+## Migration from Manual auxQueues
+
+### Before (Manual Configuration)
+```yaml
+thor:
+- name: thor-az1
+  auxQueues: [thor-prod]
+  maxJobs: 2
+  maxGraphs: 1
+- name: thor-az2  
+  auxQueues: [thor-prod]
+  maxJobs: 2
+  maxGraphs: 1
+- name: thor-az3
+  auxQueues: [thor-prod]
+  maxJobs: 2
+  maxGraphs: 1
+```
+
+### After (Logical Cluster)
+```yaml
+thor:
+- name: thor-prod
+  cluster:
+    instances: 3
+    instanceTemplate: "{name}-az{instance}"
+  maxJobs: 6
+  maxGraphs: 3
+```
+
+## Error Handling
+
+The system validates configurations and provides clear error messages:
+
+```
+Thor cluster 'thorcluster': maxJobs (5) and maxGraphs (3) must be evenly divisible by instances (3)
+```
+
+## Implementation Details
+
+The logical cluster expansion happens during Helm template processing:
+1. Templates detect Thor configurations with `cluster` properties
+2. Validation ensures proper divisibility
+3. Multiple Thor instances are generated with appropriate limits
+4. Queue configurations are updated to include both individual and auxiliary queues
