Default How looping over cells works in FLUENT UDFs?

I just have a simple 2D domain consisting of uniform hexahedral cells as shown in the attached image. I want to know the looping pattern in which looping over the cells happens. I have a total of 11232 cells. As I have understood, the cell index c is a number assigned to the cells and therefore there should be a total of 11232 values for c. Is there a way to know how begin_c_loop and end_c_loop works over the domain and in what order the looping over the cells works? I want to loop over the cells in a particular direction(say y, along each column). Can someone please help? Thanks in advance.

you may check it using udmi

put inside cell loop
Code:
C_UDMI(c,t,0) = k;
k+=1;
then plot udmi_0

Thanks for your reply Alexander. I read and found that if I am using multiple cores, then the domain is divided into a number of partitions each having its own looping pattern. To get the idea, I need to see UDFs in parallel. Hope I am right.
