SDP Design Documentation

This page contains links to the SDP's Preliminary Design Review documentation, in which our design was reviewed by the SKA Organisation and an external panel of experts. 

You can download the whole document pack as a zip file. Alternatively the key documents can also be downloaded individually from the bottom of this page.

A high-level view of the SDP system components can be seen below. This is decomposed much further in the High-Level architecture docment (first in the list below) and then the sub-components, interfaces, requirements and other considerations are developed in supporting documents.

SDP hardware

Along with other SKA consortia, SDP is working towards implementing Software Engineering Institute (SEI) approaches to its software architecture documentation. This style is useful for promoting architecture decision processes based on concrete "quality attribute" scenarios. These methods will help us with addressing the many architectural trade-offs that SDP faces - balancing scientific accuracy with long-term modifiability and performance.

The SDP proceeds apace, implementing the management changes we outlined in our last SKA eNews contribution.

We planned our work for the October-November time period so that we could support the ongoing SKA engineering activities, and so that we could continue our work on the SDP Execution Framework, as well as work on the key algorithms that we will use to do all the processing within the SDP. We've also been conducting engineering workshops to make sure that we fully understand what makes designing the SDP such a challenge.
