Message Passing Implementation (MPI)

[ni...@uom.gr.INVALID]

Hello,

I hope my email finds all of you well. I am a Phd candidate and I am 
writing back to you with regard to scheduling in Apache Storm. According 
to the MPI implementation of Storm the workers manage connections to 
other workers and maintain a mapping from task to task. Also, 
transferring takes in a task id and a tuple, and it serializes the tuple 
and puts it onto a "transfer queue”.

The question is, if there is a way to organise scheduling, such that 
certain tasks of an operator communicate to only certain tasks of the 
following operator at a given time according to the application’s 
topology (could ZeroMQ possibly do something like this?). Any hint would 
help.

Thank you in advance for your valuable help.

Kind regards,
Nicole
