English Heritage

English Heritage

Collaboration with HISAR Alex Bayliss from English Heritage Very difficult to track her down

Artefacts ~ 300BC Prof John Hines

Longbarrows ~ 3700BC Prof Alasdair Whittle

Condorised Application

Oxcalc Developed by Christoper Ramsey Developed at University of Oxford We use version 3.10

Oxcalc interprets radiocarbon data using Bayesian statistics to date archaeological artefacts based on their carbon isotope ratios

Data Collection

Scientist takes a sample of the artefactThe sample is heated until it vaporisesThe vapour is then analysedThe ratio of C12 to C14 is measured

Artefacts

Artefacts – Sensitivity

English Heritage still collecting the dataData will be available in September 2006300 – 400 artefacts (jewellery, pottery, tools)1 hour per job on a P412 – 16 days on a single workstation (E)1 hour using the entire pool (E)

Longbarrows

Longbarrows - Stability

English Heritage have collected the data6 Longbarrows in Southern England80 – 100 models per Longbarrow1 hour per job on a P420 – 25 days on a single workstation (E)1 hour using the entire pool (E)~1.5 hours total (A)

The Future

English Heritage have already paid us EH + HISAR share an internal budget code Via TRF into our internal condor account Paid £500 for 25,000 CPU Hours Currently used < 10% of those CPU Hours EH work with other institutions EH intend to use us in the future with others

Velindre Cancer Centre

Velindre Cancer Centre

Collaboration with COMSC Mary Chin and Geraint Lewis from Velindre

Radiotherapy Prof David Walker Jon Giddy

Condorised Applications

BeamNRC Simulates x-rays emitted from radiotherapy

machines based on plan filesDosXYZNRC

Splits radiotherapy plan files (pre Condor) Joins BeamNRC results files (post Condor)

Radiotherapy Machines

Condorised Application

Radiotherapist provides plan file Radiotherapist runs Perl script Perl script calls DosXYZNRC to split plan file Perl script writes 18 submit files Radiotherapist runs condor_submit 18 beams, 90 pieces, 500,000 events 1620 jobs per patient per plan 1.5 hours per job on a P4 (A)

Condorised Application

3.5 months on a single workstation (E) 3 hours using the entire pool (E) ~12 hours total (A) ~10 Gigabytes of results Radiotherapist runs another Perl script Perl script calls DosXYZNRC to join results Radiotherapist evaluates the results

The Future

Velindre have agreed to paid us V + COMSC share an internal budget code Via TRF into our internal condor account Will pay £500 for 25,000 CPU Hours Currently used ~ 30% of those CPU Hours Future potential for 1400 patients / year 3.4 million hours using the entire pool (E) 6 months using the entire pool (E)

Full Economic Costing

Background

Full economic costing is a hot topic Some guidelines available from

EPSRC, HEFCE, HEFCW JISC…Some guidelines from other universitiesNo guidelines for HPC or HTCFunding bodies require FEC in new grantsFEC of Condor was a pre-emptive strike

Total cost £1560.10 pa Assuming a 4 year update cycle

Additional Power

Measure power consumption When Idle When running a job using max CPU When running a job using max DISK

Calculate additional power consumed Max Condor = (Max CPU – Idle) + (Max DISK – Idle)
