             Summary: Model/Hybrid Partition Support
                 Key: SINGA-113
                 URL: https://issues.apache.org/jira/browse/SINGA-113
             Project: Singa
          Issue Type: Bug
            Reporter: Sheng Wang
            Assignee: Sheng Wang


This ticket is to add model partition and hybrid partition.
model/hybrid partitions are achieved by adding assistant connection layers in 
original neuralnet model to handle data/gradient messages between two connected 
layers but on different machines.

The partition is transparent to users.

User just need to configure partition_dim field in NetProto:
partition_dim = 0 : data partition
partition_dim = 1 : model partition

User can overwrite partition_dim for a specific layer in LayerProto with the 
same manner. This will result in hybrid partition.
