Can you green the academic institution?

1. Can you green the academic institution? David Wallom Technical Manager Oxford e-Research Centre University of Oxford

2. Overview • Academia in the UK and IT • Example greening solutions • Desktops • Research Computing • HTC • HPC

3. HE/FE HAVE A LARGE FOOTPRINT • 760,000 PCs • 215,000 servers • 147,000 networked printers • 512,000 Mwh of electricity • 275,000 tonnes of CO2 • Over £60 million in 2009

4. Methods for driving change • Sticks- Regulations- Energy and other costs- Stakeholder requirements • Carrots- Financial and operational benefits- Teaching and research

13. What do users need? A gateway server in the right place 1.2GHz Marvell Sheeva CPU 512 MB RAM 512 MB flash memory Gigabit LAN interface and USB 2.0 port. 1.6GHz Atom CPU 1 GB RAM 80 GB SATA-2 HDD Gigabit LAN interface and USB 2.0 ports

14. Possible outcomes • Everybody turns off their computer • Nobody turns off their computer • Somewhere between

15. Wake on LAN (WoL) Service • Encourage OFF by enable ON • A standard of decade old • Supported by most motherboards • One gateway, two services

16. Who can use the service? • Registered owner • Registered IT admin • Scheduled timer • Third party services

17. Service interfaces WS-SECURITY 3rd PARTY SERVICES SOAP MACHINE CENTRAL SERVER HUMAN HTTP REQ BROWSER KEBEROS

22. Desktop computers and energy consumption Power (kW) x Time (hours) x Number of devices x Cost (£ per kWh) 0.105 x 8760 x 16 000 x 0.12 = £1,766,000 0.105 x 1808 x 16 000 x 0.12 = £ 364,000

23. Five steps: Estimate Scenario A: 100 computers (80W) and monitors (25W) left on all year will consume 92,000 kWh over the next year: • 49,400 kg CO2eq. • £11,000 (at 12p/kWh) Scenario B: Same stock switched off at the end of each working day (over night, weekends and 25 days of holiday) will consume 19,800 kWh over the next year: • 10,600 kg CO2eq. • £2,400 (at 12p/kWh)

24. Five steps: Research Energy Star has compiled a list of case studies (mostly for US organisations) and we have started to do the same at Oxford e.g. policy at OUCS: http://www.oucs.ox.ac.uk/greenit/oucs.xml

25. Five steps: Implement Four tools: • Monitor and report • Switch computers on remotely • Automatically power down computers safely and reliably • Display real time electricity meter data

26. Five steps: Communicate • The Carbon Reduction Commitment league table • IT-related energy costs • Staff morale: It all comes down to protecting the brand of your group and the collegiate University as a whole

27. Five steps: Share Write your approach up so others can learn from your experience. For more information about the 5 steps: http://www.oucs.ox.ac.uk/greenit/desktop.xml

28. Participating Institutions • University of Liverpool, providing a location independent national service • Utilizing the above service • Manchester • York • Southampton Solent

29. Research Computing • Large contributor for institutional consumption • Crucial research facility with significant user community from across the university constituency • Institutional HPC may consume ~4-5MW • Utilisation not always 100% • Therefore; • Increasing efficiency is essential as every little step counts

30. Possible solutions • Already • Virtualisation – OK for smaller services, not large resource utilisation • Resource Management – Interface for starting and stopping workers within a task farm/beowulf cluster

31. Condor HTC Power Optimization • Integration between Condor resource management system and power control facilities • Separate daemon that manages which resources (worker nodes) are running compared to incoming task queue • Insert damping factor and ‘round-robin’ listing of workers to ensure systems aren’t turned on and off too frequently

32. Powering down Supercomputers Dr Jon Lockley

33. Project • 9 month JISC Funded Demonstrator project • Oxford Supercomputing centre and Streamline Computing • Possible to make 10-20% energy savings during normal operation

34. Background • 25-30 UK HEI with supercomputing resources • Energy use (directly and in associated facilities) is large • Any reduction in nominal consumption would result in a large saving • Resource utilisation managed by a relatively small number of job schedulers • Little vendor drive to reduce consumption

35. The plan • Actively control the compute nodes • Switch ‘on and off’ depending on load • Containing enough intelligence to power on the right number of nodes for the work queued • Job scheduler independent development to allow for widespread utilization and integration by academic and commercial systems integrators in their management stack • Initial targets are PBSPro, Torque and SGE • Maui and other DRM/JS as resources allow
