-When running the next command, we use the Hugging Face checkpoint as the initial checkpoint. We train with an 8K context window for 240 steps, a 16K context window for 290 steps, and a 24K context window for 50 steps. We run all experiments on a single 8XH100 80GB node or on a single 8XA100 80GB node.

If you're running on 8XA100 80GB, you will need at least 1 node for 8K training and 2 nodes for 16-24k training.
 
 ## Training Curve
 When using the above commands, we get the following training curve:
