> For the current version, there are two bottlenecks for the distributed MNIST_LeNet_Sdg
model training: 
>           # Data locality: for {{RemoteParForSpark}}, the tasks are parallelized without
considering data locality. It will cause a lot of data shuffling if the volume of the input
data size is large; 
>          # Result merge: the current experiments indicate that the result merge part
took more time than model training. 
> After the optimization, we need to compare the performance with the distributed Tensorflow.
