yes, that is a good idea and we should leverage this opportunity. I'm 
happy to mentor a project as well, specifically on parameter server 
architectures for distributed deep learning in SystemML.

Right now we can emulate synchronous parameter servers with parfor, but 
there are other architectures like asynchronous, stale-synchronous, 
heterogeneity-aware, and decentralized, which we should support as well 
in form of a dedicated runtime infrastructure similar to local/remote 
parfor. If done right, we should be able to leverage common primitives 
in parfor and these parameter servers.

Apart from better support for distributed deep learning, this would 
bring us much closer to the goal of a unified framework for large-scale 
machine learning as we would be the only framework that supports 
data-parallel (distributed ops), task-parallel (parfor), and 
model-parallel (parameter server) execution strategies in a single system.

I'll create an epic with sub tasks later this week. The goal would be to 
integrate these parameter servers with the underlying data-parallel 
framework to have a common runtime for distributed operations and 
automatically support all underlying resource schedulers such as YARN, 
Mesos, and Kubernetes. Since the project is relatively large, we might 
need to split it up into multiple GSoC projects along with multiple mentors.
