beyondli opened a new issue #7320: where PS-lite implementation of server 
manager & hash ring ??
URL: https://github.com/apache/incubator-mxnet/issues/7320
 
 
   while reading the ps-lite model  , I can just find how server /work / 
scheduler created .but cannot find
   
   1:**server manager** which handles the  hash ring management,  I just found 
the likely code in void Van::Receiving() fun
                 int id = node.role == Node::SERVER ?
                          Postoffice::ServerRankToID(num_servers_) :
                          Postoffice::WorkerRankToID(num_workers_);
      are these the so called "direct-mapped DHT design" in the Mu Li paper 
OSDI 2014? 
      so where is hash ring and server  manager ,so not implemented yet or in 
some models I just not found??
   
   2: since no hash ring found ,  **"virtual" servers** which can improve LB 
and recovery are also not found.
   
   so where **consistent Hashing** in paper delcared in mxnet, since it is so 
important in distributed Machine Learning
   
   anyone help is appreciated in andance!!
