[Trilinos-Users] Isoropia/Zoltan2 for general graph partitioning / TBB

[Erik Boman]

Hi Sean,

For now, the best approach is to use Isorropia with a Epetra_CrsGraph as 
you suggest. There is a lot of active development on Tpetra/Kokkos for 
shared-memory nodes, and this will eventually be interfaced with Zoltan2 
but it is work in progress.
