В статье представлен новый гидродинамический программный код AstroPhi 2.0 для численного моделирования астрофизических процессов на гибридных суперЭВМ, оснащенных ускорителями Intel Xeon Phi. Описаны детали параллельной реализации кода и элементы со-дизайна численного алгоритма, которые позволили сделать эффективную программную реализацию. В рамках одного ускорителя было получено 134-кратное ускорение, 92-процентная эффективность была получена при использовании 64 ускорителей. С помощью данного кода была смоделирована задача столкновения галактик.
