turning c# methods c++ methods

i'm exploring several options mapping common c# formula constructs c++ cuda formula controlling gpu. structure component follows (arrows paint slight calls):

c# way -> c# gpu lib -> c++ cuda doing lib

a slight gpu library feeling something this:

public stationary vacant map<t>(this icollection<t> c, func<t,t> f)
{
   //call 'f' any component 'c'
}

this an progression slight icollection<> forms runs duty any element. however, i c++ library run methods gpu. need duty be, somehow, translated c++ code. possible?

to elaborate, user library executes slight (in c#) erratic formula it, i interpret formula c++ equivelant such i run cuda. i have feeling there easy proceed nonetheless i know there any proceed grasp same effect.

one thing i wondering capturing duty interpret an countenance map c++ equivelant. anyone any trust this?
