[Trilinos-Users] [EXTERNAL] Zoltan2 RCB Bounding box algorithm not implemented

[Devine, Karen D]

I suggest you use the multijagged partitioner in Zoltan2.  Like RCB, it is a geometric method, so you would need to change only one parameter to use it (algorithm == multijagged).  The bounding boxes are implemented for multijagged.

Subject: [EXTERNAL] [Trilinos-Users] Zoltan2 RCB Bounding box algorithm not implemented

Hello all,

I am working on an application <http://github.com/biddisco/pv-zoltan> which partitions the data using Zoltan using RCB algorithm and obtains bounding boxes for each partition. Currently I am trying to replace Zoltan calls by Zoltan2 for my gsoc project. But turns out Zoltan2 is still not fully implemented in Zoltan2.

Zoltan2 has a function getPartBoxesView(). But it has not been implemented for RCB algorithm yet. So it throws runtime error saying "getPartBoxesView is not implemented in selected algorithm".

Can you please guide me how can I solve this problem? Or redirect me to related references/code fragments which might help me implementing this function?
