Loop over cells per processor (parallel)

Hi I got a problem and I have read a lot of posts on a different forums but still could not find a solution. I am doing something wrong. Could some one help me out.
Basically when I run my program on single processor it works fine but when on parallel it does not.
I am using the loop
x = mesh.C()[celli].component(0);
y = mesh.C()[celli].component(1);
z = mesh.C()[celli].component(2);
arr = getnewvelocity(rho, U[celli].x(), U[celli].y(), U[celli].z(), p[celli]);
I found a post on this forum suggesting to use "reduce" command but it means that I send all data from all proc to one. I dont want this. I wan to go through all cells per processor.
Could some one give me an advise or example.

Whether you want to do a reduce or not is irrelevant: it depends on what is happening in the location where you put the 7 points. May be that you don't need a reduce. May be that you need it after the loop.
