Subject [jira] [Commented] (SINGA-109) Refine bridge layers for inter-node layer communication
Date Fri, 04 Dec 2015 11:57:11 GMT


ASF subversion and git services commented on SINGA-109:

Commit bd2e3453ca01e7bf9bf6724b4717d956c6e00290 in incubator-singa's branch refs/heads/master
from WANG Sheng
[;h=bd2e345 ]

SINGA-109 Refine bridge layers

re-implement bridge layers for model partition
 * move socket operations for sending/receiving blobs from worker into layers,
   so that it is transparent to users who will implment TrainOneBatch
 * when initialing worker, it will create a socket instance and pass it to all
   bridge layers using layer.MakePaired() function

> Previously, sending data and gradient blobs between remote bridge layers is explicitly
handled by worker.
> Train One Batch functions need to manage sending/receiving data before doing real work.
> This ticket is to encapsulate bridge layer communications, and put them inside their
own compute feature/gradient functions.
> So that the worker do not need to know how the neuralnet is partitioned and communicated.
