[GitHub] huyangc opened a new issue #9120: Are there any params replications on Parameter Servers?

huyangc opened a new issue #9120: Are there any params replications on Parameter Servers?
URL: https://github.com/apache/incubator-mxnet/issues/9120
 
 
   I am very interested on the distributed training of mxnet. And I read [Scaling Distributed Machine Learning with the Parameter Server](https://www.cs.cmu.edu/~muli/file/parameter_server_osdi14.pdf). On that paper, Mu Li said that,
   > Live replication of parameters between servers supports hot failover.
   
   and used some structures like a key ring and params will replicated on different ps.
   
   But I am reading the code of mxnet, including the ps-lite, kvstore. But I didn't find any operation of replications. 
   
   So, I want to figure out whether I am wrong or the implementation of mxnet is a little different with the paper.
   
   Hoping for an answer!
