wangwei resolved SINGA-113.
---------------------------
    Resolution: Fixed

Need to consider the case of layers configured without partitioning.

>                 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.
