+## Testing SLURM Jobs Locally
+
+A Docker Compose environment is available for testing SLURM job scripts locally before submitting to DRAC/Compute Canada HPC clusters. This simulates a minimal SLURM environment with a controller and compute node.
+
+See [docker/slurm/README.md](docker/slurm/README.md) for detailed instructions on:
+- Starting the SLURM environment
+- Submitting and monitoring jobs
+- Adapting real job scripts for local testing
+- Troubleshooting common issues
+
+Quick start:
+```bash
+# Build and start the SLURM cluster
+docker-compose -f docker-compose.slurm.yml up -d
+
+# Access the controller to submit jobs
+docker exec -it ami-ml-slurmctld bash
+
+# Inside the container
+sinfo  # Check cluster status
+sbatch docker/slurm/examples/job_hello.sh  # Submit a test job
+squeue  # Check job queue
+```

+# SLURM Docker Environment for Local Testing
+
+This directory contains a Docker Compose setup that simulates a SLURM environment for local testing of job scripts before submitting to DRAC/Compute Canada HPC clusters.
+
+## Overview
+
+The environment consists of:
+- **SLURM Controller** (`slurmctld`): Manages job scheduling and cluster state
+- **Compute Node** (`c1`): Single compute node with 8 CPUs, 32GB RAM, and optional GPU support
+- **Partitions**: Configured to match DRAC's partition structure:
+  - `main`: Default partition for general compute jobs (max 48h)
+  - `long`: For longer-running jobs (unlimited time)
+  - `long-cpu`: CPU-only jobs with unlimited time
+
+## Configuration
+
+The SLURM configuration is based on [DRAC/Compute Canada documentation](https://docs.alliancecan.ca/wiki/Running_jobs) and matches the behavior of their clusters as closely as possible:
+
+- **Authentication**: MUNGE for inter-process communication
+- **Scheduling**: Backfill scheduler with fair-share policies
+- **Resource Management**: Cgroup-based process tracking and resource constraints
+- **GPU Support**: Optional GPU passthrough using NVIDIA Docker runtime
+
+## Prerequisites
+
+1. **Docker** and **Docker Compose** installed
+2. **NVIDIA Docker** (optional, for GPU support):
+   ```bash
+   # Install NVIDIA Container Toolkit
+   distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
+   curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
+   curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
+     sudo tee /etc/apt/sources.list.d/nvidia-docker.list
+   sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit
+   sudo systemctl restart docker
+   ```
+
+## Quick Start
+
+### 1. Build and Start the Environment
+
+```bash
+# From the repository root
+docker-compose -f docker-compose.slurm.yml build
+docker-compose -f docker-compose.slurm.yml up -d
+```
+
+Wait for both containers to start (approximately 30 seconds):
+
+```bash
+# Check container status
+docker-compose -f docker-compose.slurm.yml ps
+
+# View logs
+docker-compose -f docker-compose.slurm.yml logs -f
+```
+
+### 2. Access the SLURM Controller
+
+```bash
+# Enter the controller container
+docker exec -it ami-ml-slurmctld bash
+```
+
+### 3. Check SLURM Status
+
+```bash
+# Check cluster info
+sinfo
+
+# Check node status
+scontrol show nodes
+
+# Check partition configuration
+scontrol show partitions
+```
+
+Expected output from `sinfo`:
+```
+PARTITION AVAIL  TIMELIMIT  NODES  STATE NODELIST
+main*        up 2-00:00:00      1   idle c1
+long         up   infinite      1   idle c1
+long-cpu     up   infinite      1   idle c1
+```
+
+### 4. Submit a Test Job
+
+```bash
+# Inside the controller container, navigate to workspace
+cd /workspace
+
+# Submit a simple test job
+sbatch docker/slurm/examples/job_hello.sh
+
+# Check job status
+squeue
+
+# View job output (after completion)
+cat hello_slurm_*.out
+```
+
+### 5. Test with Real Job Scripts
+
+The repository's job scripts can be tested by copying and modifying them:
+
+```bash
+# Example: Test the training classifier job
+# Note: You may need to adjust paths and reduce epochs for quick testing
+
+# Copy an existing job script
+cp research/order_level_classifier/job_train_classifier.sh docker/slurm/examples/job_test_quick.sh
+
+# Edit to reduce runtime (e.g., fewer epochs, smaller dataset)
+# Then submit
+sbatch docker/slurm/examples/job_test_quick.sh
+```
+
+## Testing Workflow
+
+### Environment Setup Test
+
+Test that the conda environment and Poetry work correctly:
+
+```bash
+sbatch docker/slurm/examples/job_test_env.sh
+squeue  # Check job status
+cat test_env_setup_*.out  # View output after completion
+```
+
+### AMI-ML Package Test
+
+Test that the ami-ml commands are available:
+
+```bash
+sbatch docker/slurm/examples/job_test_ami_ml.sh
+```
+
+## Common SLURM Commands
+
+### Job Management
+
+```bash
+# Submit a job
+sbatch job_script.sh
+
+# Check job queue
+squeue
+squeue -u $USER  # Your jobs only
+
+# Get detailed job info
+scontrol show job <job_id>
+
+# Cancel a job
+scancel <job_id>
+
+# View completed job info
+sacct -j <job_id>
+```
+
+### Node and Partition Info
+
+```bash
+# List partitions
+sinfo -s
+
+# Show detailed partition info
+scontrol show partition main
+
+# Show node details
+scontrol show node c1
+```
+
+### Resource Monitoring
+
+```bash
+# Monitor job output in real-time
+tail -f <output_file>.out
+
+# Check cluster load
+sinfo -N -l
+```
+
+## Testing GPU Jobs
+
+If you have NVIDIA GPUs and the NVIDIA Docker runtime installed:
+
+```bash
+# Submit a GPU job
+sbatch --gres=gpu:1 docker/slurm/examples/job_gpu_test.sh
+
+# Check GPU availability
+scontrol show node c1 | grep Gres
+```
+
+To test without GPU (CPU-only smoke tests):
+- Remove or comment out the `#SBATCH --gres=gpu:*` line
+- Reduce training to 1-2 epochs
+- Use smaller batch sizes
+
+## Adapting Real Job Scripts
+
+When adapting real job scripts from `research/` or `scripts/`:
+
+1. **Module Loading**: The container uses conda directly, not `module load`
+   ```bash
+   # Real SLURM:
+   module load miniconda/3
+   conda activate ami-ml
+   
+   # Docker SLURM:
+   eval "$(/opt/miniconda3/bin/conda shell.bash hook)"
+   conda activate ami-ml
+   ```
+
+2. **Data Paths**: Use paths relative to `/workspace` (project root)
+   ```bash
+   # Real SLURM (uses environment variables):
+   --train_webdataset $ORDER_WBDS_ALL
+   
+   # Docker SLURM (use local paths or set env vars):
+   --train_webdataset /workspace/data/train_*.tar
+   ```
+
+3. **Temporary Storage**: `$SLURM_TMPDIR` works the same way in the container
+
+4. **Resource Requests**: Adjust to fit the container limits (8 CPUs, 32GB RAM, 2 GPUs)
+
+## Troubleshooting
+
+### SLURM Controller Not Starting
+
+```bash
+# Check controller logs
+docker-compose -f docker-compose.slurm.yml logs slurm-controller
+
+# Common issues:
+# - Munge key not generated properly
+# - Configuration file errors
+
+# Restart the environment
+docker-compose -f docker-compose.slurm.yml down -v
+docker-compose -f docker-compose.slurm.yml up -d
+```
+
+### Jobs Stuck in Pending State
+
+```bash
+# Check why job is pending
+scontrol show job <job_id>
+
+# Common reasons:
+# - Requested resources exceed node capacity
+# - Wrong partition name
+# - Compute node not responding
+
+# Check node state
+scontrol show node c1
+
+# If node is down, set it to idle
+scontrol update nodename=c1 state=idle
+```
+
+### Permission Issues
+
+```bash
+# Ensure workspace is accessible
+ls -la /workspace
+
+# Check SLURM user permissions
+id slurm
+```
+
+### Conda Environment Issues
+
+```bash
+# If conda environment doesn't exist, create it:
+conda create -n ami-ml python=3.9 -y
+conda activate ami-ml
+cd /workspace
+poetry install
+```
+
+## Stopping the Environment
+
+```bash
+# Stop containers
+docker-compose -f docker-compose.slurm.yml down
+
+# Stop and remove volumes (clean state)
+docker-compose -f docker-compose.slurm.yml down -v
+```
+
+## Advanced Configuration
+
+### Customizing Node Resources
+
+Edit `docker/slurm/slurm.conf` to adjust resources:
+
+```conf
+NodeName=c1 CPUs=16 RealMemory=64000 Gres=gpu:4 State=UNKNOWN
+```
+
+Then rebuild:
+```bash
+docker-compose -f docker-compose.slurm.yml build
+docker-compose -f docker-compose.slurm.yml up -d
+```
+
+### Adding More Compute Nodes
+
+Edit `docker-compose.slurm.yml` to add more nodes, and update `slurm.conf` accordingly.
+
+### Persistent Storage
+
+Job outputs and SLURM logs are stored in Docker volumes. To use host directories instead:
+
+```yaml
+volumes:
+  - ./slurm-logs:/var/log/slurm
+  - ./slurm-spool:/var/spool/slurm
+```
+
+## Differences from Real DRAC SLURM
+
+1. **Scale**: Single node vs. multi-node cluster
+2. **Modules**: No `module load` environment modules (uses conda directly)
+3. **Storage**: No scratch/project filesystem hierarchy
+4. **Accounting**: No database accounting (uses flat file)
+5. **Network**: No high-speed interconnect (InfiniBand)
+
+Despite these differences, the job script syntax, resource allocation, and scheduling behavior closely match DRAC's environment.
+
+## CI/CD Integration
+
+This SLURM environment can be used in GitHub Actions for automated testing. See `.github/workflows/test-slurm-jobs.yml` for an example workflow.
