>             Project: Singa

>            Reporter: 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.
