From 26759a82a3382bef4929765f1413058d5f71e109 Mon Sep 17 00:00:00 2001 From: Valentin Churavy Date: Tue, 17 Dec 2024 17:36:16 +0100 Subject: [PATCH 01/81] Use Adapt.jl to change storage and element type In order to eventually support GPU computation we need to use Adapt.jl to allow GPU backend packages to swap out host-array types like `CuArray` with device-side types like `CuDeviceArray`. Additionally this will allow us to change the element type of a simulation by using `adapt(Array{Float32}`.
