 ## Launch Agent(s) Across Multiple Tasks

+You can launch one (or multiple) agents to solve many tasks in parallel, each in an isolated deployment of OpenApps, using SLURM:
 
 ```
-uv run launch_sweep.py
+uv run launch_parallel_agents.py mode=slurm_cluster agent=dummy use_wandb=True
+```
+
+This launches 6 parallel independent random click agents to solve each task in each app variation as defined in `config_parallel_tasks.yaml`
+
+```yaml
+parallel_tasks:
+  _target_: open_apps.tasks.parallel_tasks.AppVariationParallelTasksConfig

-* Note each deployment of OpenApps can have different appearance and content
-* Note each task is launched in an isolated environment to ensure reproducible results. -->
+You can modify the set of tasks or app variation by updating the `config_parallel_tasks.yaml`. We ensure:
+
+* Each deployment of OpenApps can have different appearance and content per app.
+* Each task is launched in an isolated environment for reproducible results.
