I have some multiple points constraint input as follows,

A_1 a_4 

B_2 b_5

C_3 c_6

each columns are stored in different IS.

After dmplex distribute, they will be renumbered and distribution to certain processors. 

I have two questions:

(1) I need both complete ISs are all the processors. Can I just do ISALLGather()?

(2) Although renumbered, will the original order remain(ABC and abc)?

If the number is the node number, after distribution and I do an ISALLGather()

will I have the following on each processor?

A_3 a_1

B_4 b_2

C_6 c_5

(I randomly renumber them)

This is what I can come up with now. Is there any better way to do it? 

Thanks,

Josh
