1 SKA Industry Update Matthew Johnson Head of the UK SKA Project Office STFC

2 Square Kilometre Array Rebaselining announced in March 2015 UK selected as HQ host in April 2015 Business case approved by Jo Johnson in BIS in July 2015 Formal negotiations to establish treaty now underway UK leads on work packages (Manchester and Cambridge) Construction set to begin in 2018

3 SKA and STFC The UK is contributing 100M towards the construction of SKA Phase 1 via STFC. STFC is working with the BIS, Innovate UK, KTN and UKTI to develop and execute the industry strategy and support UK Industry. Construction is planned to commence in UK Universities are key to pre-construction activities.

4 SKA Timeline

5 SKA Timeline

6 Procurement The Procurement Policy for the SKA is currently under development. STFC is playing a key role in that development. SKA will have single national contacts for procurement in each member country. STFC is the single point of contact for UK. Currently building a publicly facing UK industry database of companies You can register also.

7 If you register you will receive information about: Latest SKA project developments. SKA procurement news. How to access future tender opportunities at the SKA. Upcoming events to link you with the SKA. How to collaborate with companies in other SKA member states. How to access tender opportunities at other STFC funded international science facilities. As well as a company profile on the UK industry SKA database.

14 International SKA Headquarters Jodrell Bank has been selected as the permanent SKA HQ location Public limited company 10 member countries Aim for IGO in 2017 Phase 1 650M cost cap HQ at Jodrell Bank 9 international consortia UK lead SADT, SDP 120M for 4-year design SKA to be industry built Too large for universities and research institutes. UK has committed 100M towards build

15 Dishes 15m offset Gregorian dishes; surface good to 20GHz ~5 pointing; 3 deg/s slew rate; cryogenic receivers Phase 2 will see 2500 dishes across Africa

16 Low frequency Array: Each antenna has 2 x LNA, RFoF 1,000,000 in Phase 2. 16

23 SKA Science Data Processor: Industry Engagement Mike Ashworth STFC Hartree Centre and Scientific Computing Department STFC Daresbury Laboratory

24 SKA A Big Data Challenge Antennas Digital Signal Processing (DSP) HPC Processing 2020: 100 PByte/day 2028: 10,000 PByte/day Over 10s to 1000s km Transfer antennas to DSP 2020: 20,000 PBytes/day 2028: 200,000 PBytes/day Over 10s to 1000s km HPC Processing 2020: 300 PFlop 2028: 30 EFlop High Performance Computing Facility (HPC)

25 SKA Science Data Processor The SDP consortium led by Paul Alexander University of Cambridge 3 year design phase started November 2013 To deliver SKA ICT infrastructure need a strong multi-disciplinary team Radio astronomy expertise HPC expertise (scalable, advanced software; management) HPC hardware (advanced processors; interconnects; storage) Big Data expertise (streaming, data management, metadata) Building a broad global consortium: 11 countries: UK, SA, Aus, NZ, Canada, NL, Germany, China, France, Spain UK: Cambridge, SCD Hartree Centre, Oxford, Manchester Radio astronomy observatories; HPC centres; industrial partners; subcontractors

26 SKA is a Streaming Data Processor Ingesting and processing data streaming at 6-12 TB/s from the correlator; Processing individual observations from single figure PB up to 70 PB; Delivering Exascale processing power on site within stringent cost and power constraints; Archiving around 300 PB/year; and Delivering science products from remote locations in South Africa and Australia to astronomers across the globe.

28 Industrial Participation We recognise that there is a lot of expertise in the industry sector We are working or would like to work with partners in the following areas: Hardware technologies Low power processors, interconnects, memories, disks etc. Storage class memory a.k.a. solid state disk Accelerators: GPUs, Xeon Phi, etc. FPGA-based computing solutions Software technologies Parallel languages, libraries and frameworks Novel algorithms for FFTs, convolution, image processing etc. Novel solutions for knowledge discovery from huge datasets Approach: Co-design of software and physical layer architectures

29 SKA: a UK Government priority 2.9 billion for a Grand Challenges Fund, which will allow us to invest in major research facilities of national significance, such as the new Alan Turing Institute, and projects such as the Polar Research Ship and Square Kilometre Array Conservative Party Manifesto, 2015

30 Summary o SKA will be the largest scientific project on Earth o Its construction will require the industrialisation of radio astronomy. o Major benefits to the participating countries o Once operational, the SKA will deliver transformational science for 50 years. o Understanding of Cosmic Dawn (earliest stages of the Universe), gravitational waves and clues as to the origins of life may all deliver Nobel Prizes.

31 How to connect and engage o Aim to establish IGO mid-2017 o SKAO can then define its own procurement policy o Construction to start 2018 o STFC developing UK SKA industry strategy now o STFC contacts: o julie.bellingham@stfc.ac.uk o Matthew.johnson@stfc.ac.uk
