I tried having the inner for-loop (`for h in upagents`) on the GPU. But, I couldn’t find alternatives to a few commands that are in there. I posted about it here - [Rewriting function on CPU for execution on GPU](https://discourse.julialang.org/t/rewriting-function-on-cpu-for-execution-on-gpu/31608)
