Hi,
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.
So one IS lists the capital letter and one lists the lowercase?
After dmplex distribute, they will be renumbered and distribution to certain processors.
Plex does normally renumber and send ISes, so you are doing this yourself?
I have two questions:
(1) I need both complete ISs are all the processors. Can I just do ISALLGather()?
I think so. I cannot tell what you want to do.
(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?
Can you tell me what you want to use this for? Maybe there is an easier way. For example, if we want to impose a constraint on a mesh point, usually I mark that point with a DMLabel. These are propagated during distribution so you do not have to think about it. Thanks, Matt
Thanks, Josh
