The SABSA (Sherwood Applied Business Security Architecture) framework is a useful generic means of exploring users’ preferences for reducing residual risks to acceptable levels given budgetary (financial, resource, time frames etc.) constraints while traceably supporting business objectives. This talk presents why and how SABSA can be used in the...

Recent work undertaken by the joint ASTRON-IBM DOME project confirms earlier work pointing towards exascale compute requirements for SKA Phase 1 image synthesis data processing. Required ingest data rates are estimated to be multiple terabits per second. What drives these extraordinarily challenging requirements? What would be required to sustainab...

Spreadsheet showing links between risks identified in Software and Computing CoDR and generic risks for HPC identified in CMU-SEI Technical Note 2006 TN 039

The main aims of SKA CoDRs are to: • Critically review candidate solutions, technology trends and alternative options • Review the status of work done and underway by Precursors, Pathfinders and Design Studies • Conduct preliminary investigations into requirements, interfaces, costs and risks

This document describes the plan for the Software and Computing Concept Design Review (CoDR) for the Square Kilometre Array (SKA) project. This document describes matters related to the review itself, logistics of the review, and it includes a preliminary agenda for the review.

Presentation to the SKA Software and Computing Concept Design Review

This document supports risk management – identifying and proposing mitigation plans – for the Software and Computing CoDR, and in turn it informs the SKA System Level Risk Register.

Given the likely scope and scale of software development required for the SKA, development of software and computing architectures during the SKA’s Definition Phase should demonstrate that plans are in place to work towards levels of process maturity above CMMI Level 1.
