Training of neural networks with gradient methods. Here we suppose that we

1). initialize all we need
2). data preparation
3). loop until convergence
a). read a batch of samples from the input file
b). reset the worker
c). forward computation with the input
d). backward computation with respect to the loss
e). collect the gradient (neccessary when several workers are available)
f). update the model (on the server end)
g). distribute the new model to each worker
Here a worker processes a batch of samples one time, and works with
other workers independently. The server is the origanizer. It distriute
the job to the workers and maintain the model.
