Hi. For solving the reaction equations, ReactorCvode is generally used in PeleLMeX. The react function in ReactorCvode is divided into two regions, GPU and CPU. What exactly is the difference between the two regions? As far as I understand, the reaction integration takes place cell by cell in the CPU region, and in the GPU region, the state vector has all the information at all the cells at the current AMR level, and reaction equations are solved all together at once. Is that correct?
