-----------------------------
Summary: Improve hybrid partitioning and benchmark performance
Key: SINGA-135
URL: https://issues.apache.org/jira/browse/SINGA-135
Project: Singa
Issue Type: Improvement
Reporter: wangwei
Assignee: Sheng Wang
SINGA now supports partitioning on batch dimension and feature dimension. Given
more than two workers per group, every layer is partitioned. It is possible
that some layers are not suitable for partitioning, e.g., the SoftmaxLossLayer
in Alexnet. To handle that case, a special value should be configured for that
layer's partition dimension field, e.g., -1.
With all partitioning dimensions implemented, we can bench mark the performance
of different partitioning schemes. The benchmark task could be in a new ticket
or in this ticket.
