Dr Arthur Trew EPCC Director A Research Computing Infrastructure for Edinburgh

who are we building this for? local researchers, eg. –Computational: UoE HPC service, BlueGene/L, BlueDwarf … –Data: ScotGrid, QCDGrid, eDIKT, … national research consortia –Computational: QCDOC, HPCx, DEISA –Data: NDCC visitors –Computational: HPC-Europa visitor programme –Data: eSI … new projects/bids –HECToR, Brain Imaging, systems biology … –next generation machine design …

what’s the problem? we thought it was networking and CPU … but, a survey of users added data … BIG TIME!... and this projection only included projects with secured funding TB

in summary while individual needs varied all required some mixture of –more CPU/memory –more data storage –faster access researchers were used to buying their own CPU servers so, our strategy was to complement this by providing a support infrastructure Stage 1: we used £1.68 M of SRIF1 to: –create a fast, research network in parallel with edlan –install a research data storage facility

… and data too 155 TB SAN + 36 TB tape backup –available to all e-science researchers total investment SRIF1 + project funds: £2.2M

short of space … but all the new facilities could not be fitted in the JCMB machine room £4.2M from SRIF2 to refurbish a new research computing facility

what facilities are available to me? CPU –UoE HPC service (lomond) – 52-pe Sun E15000 –BlueGene/L (bluesky) – 2,000-pe IBM R&D machine –capability computing for the initiated data –research SAN – 155TB (disk), 36TB (tape) Sun 6290 networking –SRIF network secure machine room space … me with your needs and we’ll see what we can do other facilities by arrangement with project owners –BlueDwarf, ScotGrid,

a free lunch? the ACF is a strategic University facility –and hence open to all researchers although a real capital asset, the recurrent support for –facilities management –maintenance, power, space charges … –and, perhaps, user support and applications porting/tuning … has to come from project funds what is it you want/need?
