This document need not cover how to integrate a parameter server in SystemML
(which comes later), but should discuss following questions:
1. Should we integrate existing parameter server implementation or build one
from scratch ? What are the pros and cons of each approaches ? For example:
https://github.com/rjagerman/glint
2. If we plan to integrate existing parameter server implementation, what is
the interface ? (for exampe: update(matrix, new matrix) or update(matrix,
delta)).
3. Can parameter server help in ML algorithms ? Some experiments might be
helpful.
