1 Where is Ireland in the Global HPC Arena? and what are we doing there? Dr. Brett Becker Irish Supercomputer List College of Computing Technology Dublin, Ireland

2 Outline The Irish Supercomputer List Ireland on the Top500 HPC in Ireland Today Comparisons & Trends Hardware & Applications (Case Study: Trinity Centre For High Performance Computing) Other adventures in Irish HPC

3 The Irish Supercomputer List Started in June 2013 First list November 2013 List updated in June and Nov of each year Roughly one week after Top500 releases Currently on 3 rd List (Nov 2014)

4 The Irish Supercomputer List Maintenance Committee Kevin Casey (DCU, former UCD, TCD) John Regan (University of Helsinki, former TCD) Mike Salter-Townsend (Oxford, former TCD) Brett Becker (former UCD) Advisory Committee Kostas Katrinis (IBM Ireland) Rolf Riesen (Intel) David Power (Boston Ltd) Simon Appleby (SGI) Dimitrios Nikolopoulos (Queen s University Belfast)

5 Missions 1. To form a central point for HPC installation operators and users in Ireland across all sectors, public and private, including (but not limited to) academic, research, industry and government. 2. To improve the awareness of HPC amongst the Irish public. 3. To represent and enhance the profile of the HPC landscape domestically and internationally. 4. To serve as a globally-facing resource representing Irish HPC, in keeping with both global and national conventions. 5. To identify current and emerging trends in Irish HPC, which can then be compared to those identified in global lists. 6. To provide a list whose statistics are representative of the Irish HPC landscape, for use by anyone for any purpose.

6 The Irish Supercomputer List to-date Divided into two lists High Rmax List ( 10 TFlops/s) currently 10 machines Low Rmax List (<10 TFlops/s) currently 15 machines Industry, Research, Academia The list has included two Top500 machines ICHEC Fionn (#358 Nov 13, #476 Jun 14) Anonymous Software Company (#434 Nov 13) Five former Top500 machines ICHEC (Stokes) Anonymous (Web, Gaming x3)

7 Ireland Global Performance Small number of Top500 machines Makes comparisons with other Top500 countries highly variable Sometimes great, sometimes not great Nov 2013: 2 x Top500 machines 5 th in world for Top500 machines per capita! Nov 2014: 0 Top500 machines Fionn lasted one year #358 Nov 13 > #476 Jun 14 > N/A Nov 14

49 To where from here? EU-West (Dublin) is Amazon s second-largest data centre. Together with US-East (Virginia) these two account for ¾ of all AWS usage [2] [2]

50 To where from here? By some counts, EU-West (Ireland) accounts for 17% of AWS servers

51 To where from here? Nobody really knows how many instances you can get at any one time from any one [Amazon] region. Dave Powers (Cycle Computing) Amazon to Build Data Centres in 'Every Large Country' in Cloud Push (November 2014) [3] What will this bring to (what does this mean for) Ireland as Cloud HPC ramps up? [3]

52 To where from here? 1. ICHEC, Industry and cloud are the only hopes for Top500-class machines in Ireland.??? Power consumption is too great for individual academic institution 2. Increased accelerator use 3. Sort-term (CPU) core counts are actually going down while performance is going up Good chips: Faster clock speeds, more ops/cycle, larger caches Power a major consideration Accelerators playing larger part

53 To where from here? What about leveraging the cloud more for HPC a-la Cycle Computing? What are Microsoft, Google and other large data-centre holders doing in Ireland? We at least know a little about Amazon

54 To where from here? Google Compute Engines are probably in Ireland and Oklahoma [4] [4]
