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

[Abhishek Kumar]

Karen,

Thanks for the response but I have some more doubts about Zoltan2
implementation.

How do we migrate data in Zoltan2? I couldn't find any function for that.
In Zoltan we could attach callbacks to Zoltan handle which would pack data,
migrate points and unpack data followed by migration of corresponding
cells, bounding boxes etc.

Have the callbacks are completely removed from Zoltan2 or they have not
been implemented yet? And how do we perform the migration step in Zoltan2
or we'll have to do it manually? Please share any examples you might have
of Zoltan2 for the same.
