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.

Lovell telescope behind new SKA HQ building on 17 Jan 2019

At the end of October 2018 the SKA SDP Consortium submitted its Critical Design Review (CDR) documentation pack. Contained in this were the formal deliverables of the design consortium covering all aspects of the SDP architecture, system engineering and programmatics (the documents are available here).  The documents were received by the CDR reviewers (consisting of 3 external members and 15 internal to SKAO) who proceeded to generate clarification questions, requests and notes in the form of observations (called OARs after the Observation Action Register approach commonly used for them). Where possible these were addressed via communication exchanges in JIRA OAR tickets.

From 15th to 19th January 2019 members of the SDP Consortium then visited the SKAO HQ at Jodrell Bank (see figure 1), where direct discussions took place in the new SKAO Council Chamber (see figure 2), to further explore the architecture and identify risks as part of an SEI Architecture Tradeoff Analysis Method (ATAM).


At the end of October the SDP Consortium submitted its full document set for Critical Design Review. (These can be found at http://ska-sdp.org/publications/sdp-cdr-documentation) together with a large number of supporting memos (http://ska-sdp.org/publications/released-sdp-memos-i and http://ska-sdp.org/publications/released-sdp-memos-ii). Table 1 below shows the documents in three main categories: those associated with software and hardware architecture; those explaining the supporting prototyping work that has been undertaken in support of the architecture, and finally those associated with system engineering (SE) and programmatics aspects (e.g. specifications for how SDP interfaces with the wider telescope systems and how components will be constructed). The documents will receive observations from a panel of reviewers up until the end of December. Responses to the observations and scenarios to ‘test’ the architecture will then be discussed at a review meeting from 15th to 18th January 2019 at Jodrell Bank.
