[jira] [Updated] (HORN-25) Syncopated synchronization for parallel
SGD
[ https://issues.apache.org/jira/browse/HORN-25?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Edward J. Yoon updated HORN-25:
-------------------------------
Description: The legacy code is two barriers for merging and broadcasting updates among workers and master. We can reduce this to one barrier by using a syncopated synchronization. For example, master sends previous updated weights and computes newly received updates during waiting for next updates from workers. This will improve the performance dramatically I think.
