Subject [jira] [Updated] (SYSTEMML-2086) Initial version of local backend
Date Wed, 09 May 2018 15:57:00 GMT

     [ https://issues.apache.org/jira/browse/SYSTEMML-2086?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

LI Guobao updated SYSTEMML-2086:
--------------------------------
    Description: 
This part aims to design and implement a local execution backend for the compiled “paramserv”
function. It consists of the implementations of partitioning the data for worker threads,
launching the single-node parameter server in CP, shipping and calling the compiled statistical
function and creating different update strategies. We will focus on
implementing BSP execution strategies, i.e., synchronous update strategy including per epoch
and per batch. And other update strategies (e.g. asynchronous, stale-synchronous) and checkpointing
strategies should be optional and will be added if time permits. The architecture for synchronous
per epoch update strategy is illustrated below.
