  1. Greener modelling on greener computers Dr. Julian Dean Sheffield centre of magnetic materials and devices Working with very PC Professors T. Schrefl J. Harding Dr’s C.L. Freeman A. Goncharov G. Hrkac Phd students S. Bance M.A. Bashir N. M. Saiden

  2. What we do Micro magnetic modelling of magnetic materials Magnetic simulations (nano wires, hard drives, magnetic materials) Atomistic and quantum mechanic simulations Structural analysis for sensors We require lots of processors and memory constantly running

  3. What we have now Clustervision Departmental computer cluster (18 nodes, dual processor, dual core with 16 Gb memory each) – 72 processors Plus - 1 cluster of 10 various different PC’s running Linux, mainly Viglen - 40 processors Housed in a cooled room for 2 cluster racks of 20 nodes 1 PC per student and staff ~ 11 Pc’s

  4. Upgrades – why are we concerned A simple comparison for power and price: Greener alternative (provided by Very-pc) VeryPC Janus II Typical Computer HP DL360G5 2 servers ~ £1500 (each) (2 x quad core)– 8 processors 1 servers ~ £3800 (each) (2 x quad core) - 8 processors Cost On 0% Load (per node) 162 W 81 W On 100% Load (per node) 287 W 143.5 W

  5. Upgrades - why If we assume we run at average 80% utilization, with a PUE of 2 (conservative A/C consumption estimate), 24/365 3 year projection (@ £0.14/kwh) Greener alternative (Very-PC) VeryPC Janus II Typical Computer 2 x HP DL360G5 £4459 £1927 Saving ~ £600 per year CO2 Saved over 3 years per unit: Approx 9 Tons ~1.25 Range Rover Sports or 215 average Trees.

  6. Upgrades – reasons Reduces the cooling required – saves university space Makes us feel better – Raises university profile What we would like More support and advertisement of such systems Incentive for going green –> it would cost ~20% more in some cases to go green, but we are saving universities money. A subsidised policy would be beneficial for both sides.
