I have a large system of ordinary differential equations, and the right-hand side of the equation is coupled and time-consuming. I have written code that parallelizes the evaluation of the right-hand side over multiple threads and machines, but I am not sure whether this is the right way to do it. Below I have MWE that implements the parallelization. Is this the most efficient way of doing it or is there a better way?

```
using DifferentialEquations
using Distributed
addprocs(4)
function eoms!(du, u, p, t)
fill!(du, 0.0)
lambda = -1.0
bins = length(u)
num_workers = nworkers()
chunk_size = div(bins, num_workers)
ranges = [(1 + (i - 1) * chunk_size, min(i * chunk_size, bins)) for i in 1:num_workers]
futures = [remotecall(parallel_function, w, du[r[1]:r[2]], u[r[1]:r[2]], lambda, r) for (w, r) in zip(workers(), ranges)]
for (localfuture, r) in zip(futures, ranges)
local_du = fetch(localfuture)
du[r[1]:r[2]] .= local_du
end
end
@everywhere function parallel_function(du, u, lambda, r)
for i in 1:(r[2]-r[1]+1)
du[i] = lambda * u[i]
end
return du

end

end
