Detailed Description

template<typename Adapter>
class Zoltan2::AlgBlock< Adapter >

Block partitioning method.

Parameters

env	library configuration and problem parameters
problemComm	the communicator for the problem
ids	an Identifier model

Preconditions: The parameters in the environment have been processed (committed). No special requirements on the identifiers.

Todo:

Block partitioning uses one weight only

check for memory allocation failures

The metrics come out really bad. Is it an error in algorithm or in metrics.
