From 45019f4ebc6b8027583019010dfea888df03fa69 Mon Sep 17 00:00:00 2001 From: ChrisRackauckas Date: Sat, 30 Aug 2025 10:35:09 -0400 Subject: [PATCH 01/42] Fix #106: Add generic cache iteration for DifferentiationInterface compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Added generic fallback methods for add_node_jac_config! and add_node_grad_config! that iterate through cache fields and apply operations to AbstractArray fields - This allows compatibility with DifferentiationInterface types that OrdinaryDiffEq now uses for AD during implicit solves - Maintains backward compatibility with existing FiniteDiff and ForwardDiff types - Also includes the OrdinaryDiffEqCore and OrdinaryDiffEqRosenbrock dependencies from PR #109 since these are needed for the cache types The generic approach works by: 1. Iterating through all fields of the cache/config object 2. Applying add_node!/remove_node! to any AbstractArray fields 3. Handling special cases like colorvec updates when present 4. Using try-catch to gracefully handle immutable or unsupported fields 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Project.toml | 4 + src/MultiScaleArrays.jl | 2 +- src/diffeq.jl | 175 ++++++++++++++++++++++++++++++++++++++-- 3 files changed, 174 insertions(+), 7 deletions(-) diff --git a/Project.toml b/Project.toml index 299e975..bfdf9ba 100644 --- a/Project.toml +++ b/Project.toml @@ -9,6 +9,8 @@ FiniteDiff = "6a86dc24-6348-571c-b903-95158fe2bd41" ForwardDiff = "f6369f11-7733-5829-9624-2563aa707210" LinearAlgebra = "37e2e46d-f89d-539d-b4ee-838fcccc9c8e" OrdinaryDiffEq = "1dea7af3-3e70-54e6-95c3-0bf5283fa5ed" +OrdinaryDiffEqCore = "bbf590c4-e513-4bbe-9b18-05decba2e5d8" +OrdinaryDiffEqRosenbrock = "43230ef6-c299-4910-a778-202eb28ce4ce" Random = "9a3f8284-a2c9-5f02-9a11-845980a1fd5c" RecursiveArrayTools = "731186ca-8d62-57ce-b412-fbd966d074cd" Statistics = "10745b16-79ce-11e8-11f9-7d13ad32a3b2" @@ -25,6 +27,8 @@ DiffEqBase = "6.5" FiniteDiff = "2.3" ForwardDiff = "0.10" OrdinaryDiffEq = "5.33, 6" +OrdinaryDiffEqCore = "1.30.0" +OrdinaryDiffEqRosenbrock = "1.17.0" RecursiveArrayTools = "1,2,3" SparseDiffTools = "1.6, 2" Statistics = "1" diff --git a/src/MultiScaleArrays.jl b/src/MultiScaleArrays.jl index ec49735..09456ef 100644 --- a/src/MultiScaleArrays.jl +++ b/src/MultiScaleArrays.jl @@ -172,7 +172,7 @@ abstract type AbstractMultiScaleArrayLeaf{B} <: AbstractMultiScaleArray{B} end abstract type AbstractMultiScaleArrayHead{B} <: AbstractMultiScaleArray{B} end using DiffEqBase, Statistics, LinearAlgebra, FiniteDiff -import OrdinaryDiffEq, StochasticDiffEq, ForwardDiff +import OrdinaryDiffEq, OrdinaryDiffEqCore, OrdinaryDiffEqRosenbrock, StochasticDiffEq, ForwardDiff Base.show(io::IO, x::AbstractMultiScaleArray) = invoke(show, Tuple{IO, Any}, io, x) Base.show(io::IO, ::MIME"text/plain", x::AbstractMultiScaleArray) = show(io, x) diff --git a/src/diffeq.jl b/src/diffeq.jl index ba494a5..c74095e 100644 --- a/src/diffeq.jl +++ b/src/diffeq.jl @@ -54,7 +54,7 @@ function remove_node_non_user_cache!(integrator::DiffEqBase.AbstractODEIntegrato end function remove_node_non_user_cache!(integrator::DiffEqBase.AbstractODEIntegrator, -

Key changes: 1. Added DifferentiationInterface as a dependency 2. Implemented resize_jac_config!() function that uses DI.prepare!_jacobian for DifferentiationInterface types when function and backend are available 3. Falls back to conservative field-by-field approach for other types 4. Updated cache resizing functions to use the new approach This addresses the issue where OrdinaryDiffEq now uses DifferentiationInterface for AD during implicit solves, and the existing MultiScaleArrays code had hardcoded support only for FiniteDiff and ForwardDiff types. The solution follows the recommendation from @gdalle to use prepare!_jacobian for adapting preparation to different input dimensions. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Project.toml | 1 + src/MultiScaleArrays.jl | 1 + src/diffeq.jl | 53 ++++++++++++++++++++++++++++++++++------- 3 files changed, 47 insertions(+), 8 deletions(-) diff --git a/Project.toml b/Project.toml index f437ea4..9b8b2af 100644 --- a/Project.toml +++ b/Project.toml @@ -5,6 +5,7 @@ version = "1.15.0" [deps] DiffEqBase = "2b5f629d-d688-5b77-993f-72d75c75574e" +DifferentiationInterface = "a0c0ee7d-e4b9-4e03-894e-1c5f64a51d63" FiniteDiff = "6a86dc24-6348-571c-b903-95158fe2bd41" ForwardDiff = "f6369f11-7733-5829-9624-2563aa707210" LinearAlgebra = "37e2e46d-f89d-539d-b4ee-838fcccc9c8e" diff --git a/src/MultiScaleArrays.jl b/src/MultiScaleArrays.jl index 09456ef..7b6e58c 100644 --- a/src/MultiScaleArrays.jl +++ b/src/MultiScaleArrays.jl @@ -173,6 +173,7 @@ abstract type AbstractMultiScaleArrayHead{B} <: AbstractMultiScaleArray{B} end using DiffEqBase, Statistics, LinearAlgebra, FiniteDiff import OrdinaryDiffEq, OrdinaryDiffEqCore, OrdinaryDiffEqRosenbrock, StochasticDiffEq, ForwardDiff +import DifferentiationInterface as DI Base.show(io::IO, x::AbstractMultiScaleArray) = invoke(show, Tuple{IO, Any}, io, x) Base.show(io::IO, ::MIME"text/plain", x::AbstractMultiScaleArray) = show(io, x) diff --git a/src/diffeq.jl b/src/diffeq.jl index f756850..0c586b7 100644 --- a/src/diffeq.jl +++ b/src/diffeq.jl @@ -86,7 +86,11 @@ function add_node_non_user_cache!(integrator::DiffEqBase.AbstractODEIntegrator, i = length(integrator.u) cache.J = similar(cache.J, i, i) cache.W = similar(cache.W, i, i) - add_node_jac_config!(cache, cache.jac_config, i, x) + + # Handle jacobian config resizing + # Try to use the proper DI approach if possible, otherwise fall back to field-by-field + resize_jac_config!(integrator.f, cache.jac_config, integrator.u, cache) + add_node_grad_config!(cache, cache.grad_config, i, x) nothing end @@ -97,7 +101,10 @@ function add_node_non_user_cache!(integrator::DiffEqBase.AbstractODEIntegrator, i = length(integrator.u) cache.J = similar(cache.J, i, i) cache.W = similar(cache.W, i, i) - add_node_jac_config!(cache, cache.jac_config, i, x, node...) + + # Handle jacobian config resizing + resize_jac_config!(integrator.f, cache.jac_config, integrator.u, cache) + add_node_grad_config!(cache, cache.grad_config, i, x, node...) nothing end @@ -108,15 +115,44 @@ function remove_node_non_user_cache!(integrator::DiffEqBase.AbstractODEIntegrato i = length(integrator.u) cache.J = similar(cache.J, i, i) cache.W = similar(cache.W, i, i) - remove_node_jac_config!(cache, cache.jac_config, i, node...) + + # Handle jacobian config resizing + resize_jac_config!(integrator.f, cache.jac_config, integrator.u, cache) + remove_node_grad_config!(cache, cache.grad_config, i, node...) nothing end -# Generic fallback for any jac_config type - conservatively handle unknown types +# High-level function to properly resize jacobian configurations +function resize_jac_config!(f, jac_config, u, cache) + # For DifferentiationInterface types, use prepare!_jacobian when dimensions change + # This is the recommended approach as mentioned in the PR discussion + typename = string(typeof(jac_config)) + if occursin("DifferentiationInterface", typename) && hasproperty(jac_config, :backend) + try + # Use the proper DI API to resize the configuration + backend = getfield(jac_config, :backend) + DI.prepare!_jacobian(f, jac_config, backend, u) + return + catch e + # If DI prepare!_jacobian fails, fall back to field-by-field handling + @debug "DI prepare!_jacobian failed, falling back to field-by-field approach" exception=e + end + end + + # Fallback approach for non-DI types or when DI approach fails + i = length(u) + add_node_jac_config!(cache, jac_config, i, similar(u, 0)) + nothing +end + +# Generic fallback for any jac_config type - handle DifferentiationInterface types properly function add_node_jac_config!(cache, config, i, x) - # For DifferentiationInterface and other unknown types, try to handle arrays conservatively - # Only touch fields that we know are safe to modify (like fx in Jacobian caches) + # The proper solution for DifferentiationInterface types is to use prepare!_jacobian + # when the input dimensions change.
