Keeping a set of nodes in the same partition
Hello,
I am trying to partition a mesh with periodic boundaries. Since this periodic boundaries are small in regard to the number of total nodes in the mesh, (for the sake of simplicity and avoiding parallel communication) i would like to partition it such that these nodes are located in the same partition.
So I'm wondering, if is there a way to achieve this with parmetis?
Thanks:

Not directly. However, you can pre-collapse those nodes that you want to keep together into a single node (and update the graphs connectivity accordingly) and then use ParMetis to partition this new graph.

Yes, i was kind of hoping to avoid that. :)
