CPNTools how to create the Concept Graph

Question

I have a concept for my Graphic, but i dont know how to rialize in CPNTools. The Arrowy are the conections between the Place and Transition.

the conections: arc: Input to InitializeInput, from InitializeInput to Chunks, from Chunks to ComputePrimeTwins, from Chunks to DistributeChunks, from ComputePrimeTwins to Results, from Results to CollectResults

colset NUM = int;
colset CHUNK = list NUM;
colset RESULT = int;

val num_start = 2;
val num_end = 1024; 
val NP = 4;

fun chunk_size(num_start, num_end, NP) = (num_end - num_start + 1) div NP;
fun remainder(num_start, num_end, NP) = (num_end - num_start + 1) mod NP;

place: 
Input([num_start, num_end]) : NUM;
Chunks([]) : CHUNK;
Results([]) : RESULT;

transition: 
InitializeInput() =
  gardient:
    Input([start, end]) = num_start
    ==> Input([start + chunk_size(num_start, num_end, NP), end]);

DistributeChunks() =
gardient:  
    Input([start, end]) = num_start + chunk_size(num_start, num_end, NP)
    ==> Chunks(divide_range(start, end));

transition ComputePrimeTwins(chunk) =
gardient:  
  Chunks([chunk | _])
  ==> Results(compute_prime_twins(chunk));

transition CollectResults() =
  Results(counts)
  ==> print("Total prime twins found: " + sum(counts));
