Describe the bug 🐞
Whenever I put an MTK system into a GPU ensemble problem, across multiple backends (Metal.jl and OpenCL.jl have been tested so far), it causes a stack overflow.
Expected behavior
I expect this to work and yield the same result as that of JLArrays.jl.
Minimal Reproducible Example 👇
# Imports
using DiffEqGPU, OrdinaryDiffEqCore
using ModelingToolkit
using ModelingToolkit: t_nounits as t, D_nounits as D
import SymbolicIndexingInterface as SII
import pocl_jll, OpenCL, JLArrays
import StaticArrays
function g(backend)
# Inline first-order system: dx/dt = -k * x
@variables x(t)
@parameters k
@named sys = ODESystem([D(x) ~ -k * x], t)
sys = mtkcompile(sys)
prob = ODEProblem{false}(sys, StaticArrays.SA[x => 1.0f0, k => 1.0f0], (0.0f0, 10.0f0))
symsetter = SII.setsym_oop(sys, [k])
prob_func = (prob, i, repeat) -> begin
u0, p = symsetter(prob, StaticArrays.@SVector[(i / 10_000) * 5f0 + 0.1f0])
remake(prob; u0 = u0, p = p)
end
monteprob = EnsembleProblem(prob, prob_func = prob_func, safetycopy = false)
@time sol = solve(monteprob, DiffEqGPU.GPUTsit5(), DiffEqGPU.EnsembleGPUKernel(backend),
trajectories = 10_000, adaptive = true, dt = 0.1f0)
end
g(JLArrays.JLBackend()) # works
g(OpenCL.OpenCLBackend()) # overflowsError & Stacktrace ⚠️

Additional context

Describe the bug 🐞
Whenever I put an MTK system into a GPU ensemble problem, across multiple backends (Metal.jl and OpenCL.jl have been tested so far), it causes a stack overflow.
Expected behavior
I expect this to work and yield the same result as that of JLArrays.jl.
Minimal Reproducible Example 👇
Error & Stacktrace⚠️
The nature of the error is the same across OpenCL and Metal.
Environment (please complete the following information):
using Pkg; Pkg.status()using Pkg; Pkg.status(; mode = PKGMODE_MANIFEST)versioninfo()Additional context
