SKAO/SDP briefing session - International Supercomputing 2017

The SKAO and SDP held a joint briefing at International Supercomputing 2017 in Frankfurt on 19 June. The primary purpose of the event was to inform the ICT vendor community of the current status of the SKA project as a whole, and the technical progress that has been made by the SDP consortium since the previous conference a year earlier.

Three presentations were given:

1. An overview of the SKA project and its current status – Miles Deegan, SKA Organisation

2. An update on the Science Data Processor project – John Taylor, U. Cambridge

3. A snapshot of recent technical directions and conclusions – Chris Broekema, ASTRON

The presentations were then followed by a question and answer session.

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.
