For the typical synchronous distributed training, some significant steps are as follows:

1. A trainer process will compute the gradients and **send** them to the parameter server (PS) nodes.
1. After the PS node received gradients came from all the Trainers, It will aggregate the
gradient variables for the same parameter into one gradient variable and then apply the aggregated
gradient to the respective parameter, finally using an optimize algorithms(SGD, Monument...)
to update the parameters.
1. The Trainer would wait for the PServers finished the optimize stage, and GET the parameters from PServer,
1. The Trainer would wait for the PS finished the optimize stage, and GET the parameters from PS,
so all the Trainers would get the same parameters.
In the synchronously distributed training, there should be a `Barrier` to synchronise the
parameters after the optimizing stage. The performance of a distributed training job would
depend on the slowest node if there were hundreds or thousands of training nodes in a
Job, the performance of synchronously distributed training might be very poor because of
the slow node. So this design doc would introduce an approach to implement
*asynchronously* distributed training in PaddlePaddle Fluid.
In Synchronous Distributed Training, there is a **barrier** on each PS to wait until all trainers processes
have completed running current mini-batch. After that, all trainers can continue to run the next
mini-batch. So, we can find that the overall performance of Synchronous Distributed Training depends
on the slowest node.
In Asynchronous Distributed Training, we don't need to wait for a global mini-bach, the optimizer on
the PS will run immediately when the gradient is uploaded to the PS from one trainer. This mode would
train such models that achieve scaling, better throughput. In this design doc, we will introduce how to
implement the Asynchronous Distributed Training base on PaddlePaddle Fluid.
