For a project, I need to do repeated successive calls to interpolation functions for thousands of data points. Parallel computing should help here but as shown here something weird is going on.
After exploring InterpolatingFunction, DistributeDefninitions, ParallelEvaluate and PackedArray I found a way to make it work as I would expect/hoped.
I have added my test notebooks that ran on both Mac and Windows which helped me to figure this out with all the examples to show the performance loss for large arrays. Here is a short summary of my findings and solution.
As asked before does anyone have any thoughts on this?
