When you write and read an XDA file in parallel the node and element
numbering is changed.
This means that nodesets can't work through a "restart" in parallel... and
even worse if you are trying to "append" to the Exodus file it doesn't work
(because that Exodus file already has a different numbering so the solution
looks "scrambled").
Further, if you have "holes" in your numbering (ie your nodes start at 500
and go to 1000) those numbers aren't preserved at all.
We must write out the element and node numbers and preserve them through a
write to XDA and a read from XDA.
Agree, disagree?
