+In this manual, we explain how to use the [`solve`](@ref) function from [OptimalControl.jl](https://control-toolbox.org/OptimalControl.jl) on GPU. We rely on [MadNLP](https://github.com/MadNLP/MadNLP.jl) and currently only provide support for NVIDIA thanks to [CUDA.jl](https://github.com/JuliaGPU/CUDA.jl).
