What is Zoltan2?

Zoltan2 is a package for load balancing and combinatorial scientific computing (CSC). CSC includes graph/matrix ordering and coloring. Top

How does Zoltan2 differ from Zoltan?

Zoltan2 covers many of the same areas as Zoltan. While Zoltan was written in C, Zoltan2 is written in modern templated C++. Zoltan2 supports arbitrary index types, and can therefore solve problems with more than 2 billion elements (32-bit limit). Zoltan2 provides input adapters for Xpetra (indirectly, both Epetra and Tpetra) data types as a convenience to Trilinos users. Top

What's the status of the Zoltan2 package?

Much of Zoltan2 should be considered experimental code. The feature set is currently small compared to Zoltan. Top
