Summary
The ACS bulk data transfer library is part of the Common Software part library that provides the software infrastructure that that allows to data transfer data between two o more ALMA subsystemsACS Components. This is based on in a commercial implementation of the DDS (Data Distribution Service) standard of publisher/subscriber of publish-subscribe pattern. The purpose of this project is to investigate ZeroMQ library as an alternative messaging system to transfer data in a similar publisher/subscriber between ALMA subsystems using the similar publish-subscribe pattern.
Objective
- Analyze the existing code in UTFSM ACSflix Prototype
- Evaluate the performance of ZeroMQ and this implementation
- Make a draft implementation of the BulkData/BulkDataNT library using ZeroMQ
- Needs to be consistent with ACS IDLs and APIs
- Perform performance analysis using bandwidth throughput and latency metrics
Schedule
- Week1: Analyze implementation of BulkData
