    Description

      Feature Set Summary

      PSS prototype pipeline with end-to-end functionality and limited performance, deployable on production PSS hardware  

      Detailed Description

      By the end of PI16 (December 2022), the goal of the Pulsar Search MVP Epic is to create a functional, end-to-end, pulsar search pipeline (Cheetah) prototype to at least Technology Readiness Level 4 (TRL4*) comprising a:

      • Correlator Beamformer (CBF) interface
      • GPU-based single pulse search (SPS)
      • FPGA- based frequency domain acceleration search (FDAS)
      • Science Data Processing (SDP) interface

      using a managed software deployment system to deploy and implement on representative production hardware (ProtoNIP/Kelvin).

      Epic Hypothesis Statement (https://www.scaledagileframework.com/epic/)

      For the pulsar science community and the SKA stakeholders 
      who undertakes cutting edge pulsar research and helps enable leading-edge radio astronomy science to be undertaken through the design of the SKA, respectively. 
      the  prototype pulsar search pipeline
      is a  an end-to-end pulsar search pipeline designed from scratch to de-risk the ability to meet the SKA's unique, challenging requirements
      that  provides a pulsar search minimum viable product (MVP) on present-day hardware with limited performance. 
      Unlike  other existing pulsar search software
      our solution  uses highly efficient C++ code and GPU and FPGA accelerators. It also demonstrates the principles of the production pulsar search pipeline deployed and implemented on representative prototype production hardware.
         
      Outcome hypothesis Provides improved confidence in the mitigation of key functional and non-functional risks prior to production development and construction hence improving the likelihood of delivering the production solution to meet SKA technical and quality requirements within construction time and cost estimates. 
      Leading Indicators -        Functional verification testing through the use of high-quality test vectors
      -        Demonstrations of PSS-SDP and PSS-CBF interfaces
      -        Continuous integration of software modules into the pulsar search (Cheetah) pipeline
      -        Early demonstration of MaaS (Metal as a Service) software deployment
      -        Continuous test coverage quality auditing
      NFRs  As well as demonstrating the ability to meet functional requirements, this development roadmap aims to emulate the deployment and execution of the pulsar search code on representative hardware in a relevant environment i.e. on the ProtoNIP cluster i.e at TRL5. This aims to provide improved confidence in the ability to: 
      -        deploy and test production code remotely
      -        meet power consumption and quality requirements
      -        meet space requirements
      -        meet emitting Radio Frequency Interference (RFI) requirements
