Hi, Lawrence.

Maybe rolling something with a ZeroMQ / 0MQ  would be a good idea.  This
could be a very fast way to pass many small messages that hand off those
connections and tasks.  http://zguide.zeromq.org/page:all

I am very intrigued by this kind of queuing and think it is the path
forward for many workflows, traditional cluster and cloud.  It allows
for asynchronous communication and fault tolerance in large distributed
systems.  I've used this to wrap a grid engine queue, passing python
objects that execute in parallel on many nodes.	 It's cool stuff.

I’m currently looking at a solution to launch an object detection app on Host, with the GUI running on Host and the compute nodes doing all the video processing and analytics part. I see this solution is similar to my approach but I couldn’t find any information on how to setup. May I know where to more info about this? As I googled, Cinelerra is a video processing editor, which has nothing to do with clustering. Can you guide me on this? Appreciate your help.
