[julia-users] Parallelization of Recursive Calls on a Tree

[Diogo Gobira]

What's the best (if it's possible) way to parallelize recursive calls on a 
recursive data structure, like a tree, allowing all the workers to update 
the nodes they received as parameter on the recursive function calls. My 
code is similar to this:

function apply_simulation(node,data)
     #Do sometinhing with the root node
     do_something(node)
     for i=1:length(node.childs)
       # Call recursivelly on each child
       apply_simulation(node.child[i],data)
     end
end

I would like to use @parallel, as shown in the code bellow. Is it possible 
for my tree object be visible and writable for all workers? 

function apply_simulation(node,data)
     #Do something with the root node
     do_something(node, data)
     *@parallel* for i=1:length(node.childs)
       # Call recursivelly on each child
       apply_simulation(node.child[i],data)
     end
end

Thanks!
