 ### Configuration
 
 The setup includes:
+- **Cross-CPU compatible Python 3.10** with generic x86-64 architecture (works on both Intel Xeon and AMD EPYC nodes)
 - **SLURM scripts** (`run_fasttd3.slurm`, `run_fasttd3_full.slurm`) configured for accelerated partition with GPU
 - **Job helpers** (`submit_job.py`, `submit_experiment_batch.py`) for single/batch job submission
 - **Monitoring tool** (`monitor_experiments.py`) for real-time experiment tracking
 - **Test script** (`test_setup.py`) for environment verification
 - **Experiment plan** (`experiment_plan.md`) with current progress and TODO tracking
-- **MuJoCo Playground environment** (`T1JoystickFlatTerrain`) working and tested
+- **MuJoCo Playground environment** (`T1JoystickFlatTerrain`) working and tested on all node types
 - **Automatic GPU detection** and CUDA 12.4 compatibility  
 - **Wandb logging** with online mode by default
 - **Paper-accurate hyperparameters** for systematic replication
+- **LD_LIBRARY_PATH configuration** for shared Python libraries
