Hello,
I would like to construct an interpolation function from a very large dataset in a serialized way(master worker) and then send it to all workers for parallel computing.
I tried `sendto(workers(),interp_function=interp_function)` from ParallelDataTransfer.jl, but I got issues similar to [https://github.com/ChrisRackauckas/ParallelDataTransfer.jl/issues/16](https://github.com/ChrisRackauckas/ParallelDataTransfer.jl/issues/16).
Is there another function I can use?
Thank you for your help,

Here’s an old but related question on StackOverflow: [for loop - Julia parallel programming - Making existing function available to all workers - Stack Overflow](https://stackoverflow.com/questions/30730507/julia-parallel-programming-making-existing-function-available-to-all-workers/38146308#38146308)
Maybe there’s a more recent answer, along using Threads ([Parallel Computing · The Julia Language](https://docs.julialang.org/en/v1/manual/parallel-computing/index.html#Multi-Threading-(Experimental)-1)) that share their memory
