URL: https://github.com/apache/systemds/pull/1131
This PR includes the closed PR #1113 and all changes proposed in its
comments. It was rebased on master and consolidated to make it easier to merge
Changes list:
- Added four new federated data partitioning schemes
- ShuffleFederatedScheme
- SubsampleToMinFederatedScheme
- BalanceToAvgFederatedScheme
- ReplicateToMaxFederatedScheme
- Added runtime balancing parameter to parameter server (has a default
parameter and is optional for the federated case)
- Different runtime balancing schemes
- RUN_MIN
- CYCLE_AVG
- CYCLE_MAX
- Simplified the federated control thread to accommodate the coming N-batch
frequency
- There is now only one UDF, which computes a given number of batches.
If more batches than the local epoch are specified it will cycle. This one
function is sufficient for batch, N-Batch or Epoch Frequencies.
- Provided a convenient way to create federated test matrices in the
Automated Test Base
- .getFedMapping() of FederationMap was refactored to getFRangeFDataMap to
avoid confusion with the method of MatrixObject with the same name.
- Updated and improved CNN.dml and TwoNN.dml scripts
