A multi-language auto-differentiation module and its application to a parallel particle-in-cell code on distributed computers
Ji Qianga, Yue Hao, Allen Qiang +1
The auto differentiable simulation is a type of simulation that outputs of the simulation include not only the simulation result itself, but also their derivatives with respect to…
