# Resources required

Ursa requires computational and storage resources that scale with the size of the project. We provide some prior usage examples to give a sense of the typical resource needs.

The resources required scales with the fire area, the number of runs (combination of I15, I15_SE, and kr values), and the resolution of the simulations. Normalized values are normalized by fire area and number of runs (e.g., normalized compute time is seconds per square kilometer per number of runs).
