Nature of problem:
Calculation of oscillation probabilities of neutrinos that originate in cosmic-ray interactions in the Earth's atmosphere and propagate through the Earth, for realistic Earth and atmospheric models and multiple flavors (optionally including sterile neutrinos and CP violation).

Solution method:
Direct solution of the Schrödinger equation for n flavors including matter effects, with sampling of the atmosphere.

Restrictions:
Energy loss and absorption of neutrinos inside the Earth is not modeled; they have to be handled independently.

Unusual features:
Completely configurable oscillation parameters (including optional sterile flavors), configurable and realistic Earth model including atmosphere.

Running time:
Roughly 100 neutrinos per second and CPU core (depends on energy and oscillation parameters).
