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
- Todo:
- check for memory allocation failures
- Todo:
- The metrics come out really bad. Is it an error in algorithm or in metrics.
