My Software Has Turned Into A Techno Turkey! Bruce Berriman Astronomy is entering an era when multi-PB data sets and simulations will be delivered to the astronomical community. Such data sets will have a profound effect on the programming model used by astronomers, for the data volumes are too large for the current model of transferring data to astronomersТ desktops: the data center of the future will have to support local processing and analysis. Applications will have to be environment agnostic and their performance will have to scale to the size of the data sets and simulations. Much of the software written by astronomers on their desktops is likely to turn into the techno turkeys of the title: it is simply not written to port or scale. I will discuss approaches to developing portable, scalable code that runs on remote servers and I will discuss the changes in programming culture that are likely to be brought about in the era of Уbig data.Ф ╧ №h╦C3HIJ╬ ╧ ўўўўщў $1$7$8$H$a$gd╦C$a$gd╦C╧ ■":p╦C░╨/ ░р=!░"░#Ра$Ра%░е<`ё < ╦CNormalOJQJmH sH tH DA@Є бD Default Paragraph FontRi@є │R  Table NormalЎ4╓ l4╓aЎ (k@Ї ┴(No List╧       аzЩ╧3HIJ╬╤Ш0АААА╜АШ0АААА╜АШ0АААА╜АШ0АААА╜АШ0АААА╜Ш0АААА╜А3HJ╬╤Ш0АААА╜АШ0АААА╜Ъ0АААА╜Ш0АААА╜Ш0АААА╜╧ ╧ ╧ ?G╤IJ╤ @АIIV3IIz╧@ @  Unknown            GРTimes New Roman5РАSymbol3Р Arial qМЁ╨h╘BЎf╒BЎf!Ёе└┤┤Аr4d┴`ЁЁ                       VГ  Helpthhthh■  рЕЯЄ∙OhлС+'│┘0М5РШи┤└╠▄ шЇ   ,8@HPX'HelpthhNormalthh1Microsoft Word 11.6.0@F├#@Кн&╠@NM╤&╠G,4■   PICT4$d   ■,, ф ЎбЄMSWD ф Ў,╕ Arial╕ ).(RwHelp-¤░c)U! -)My S-¤░c)^o-)ftwar-¤░c)Ye-) Ha-¤░c)@s-) Turn-¤░c)`e-)d I-¤░c).n-)to -¤░c).A-) Tech-¤░c)gn-)o Turkey-¤░c)в!-■╨ %)  -(Вw -¤░c)  -)    - ■ └ Ь) -¤░c)  -) Bruc-¤░c)Ue -)$Berr-¤░c)Ni-) man-  Й)P -■╨ %(▓w *0 -*0Astro-¤░c)`n-)omy-■░є)N -)is-¤░c) e-))nter-¤░c)Gi-) ng-■░є). -)an-¤░c). -)era-■░є)< -¤░c)w-)hen-■ЁW)E -)mu-¤░c)9l-) ti-¤░c)--)PB- 0╗)6 -)data  - ■ └ Ь)P -)s-¤░c)et-)$s-■░є) -)and-¤░c)E -)sim-¤░c)@u-)la-¤░c) t-) ions-■░є)L -)wi-¤░c)'l-) l-■░є)  -)be-¤░c). -)d-¤░c)e-)livered-■ЁW)z -)to -¤░c)3t-) h-¤░c)e -(Bwastron-¤░c)so-)mical-■0+)` -)c-¤░c)om-);mun-¤░c)Pi-) ty-¤░c) .-■pП)  -¤░c)S-)uch-■0+)C -)d-¤░c)a-)ta-■0+)" -)sets-¤Ё╟)L -)will-■0+)9 -)have-¤░c)Z -)a-■pП) -¤░c)p-)rofound-■pП)М -)e-¤░c)f-) fec-¤░c)7t-■pП)  -)on-¤░c). -)the-■0+)9 -)prog-¤░c)Sr-)a-¤░c)m-)#mi-¤░c)+n-)g-■0+) -¤░c)m-)#ode-¤░c)El -(qwused-¤░c)Z -) by astron-¤░c)лo-)mer-¤░c)Gs-), for-¤░c)G -) the -¤░c)Ed-)ata v-¤░c)Zo-)lu-¤░c) m-)#es are t-¤░c)Лo-)o lar-¤░c)Qg-)e for -¤░c)_t-) he curren)░t-¤Ё╟)  -) m-¤░c)"o-)del -¤░c)Co-)f tr-¤░c)0a-)nsferrin-¤░c)Кg -)$da-¤░c).ta -(бwto-■0+)" -)a-¤░c)s-)tron-¤░c)Go-)mers╒-¤Ё╟)e -)des-¤░c)Ck-)tops-¤░c)N:-■0+)  -)th-¤░c)"e-■0+) -)d-¤░c)a-)ta-¤Ё╟)" -)ce-¤░c),n-)ter-¤Ё╟)0 -¤░c)o-)f-■0+)  -)the-¤░c)9 -)fu-¤░c)"t-) ur-¤░c)%e-■0+) -)will -¤░c)Gh-)ave-¤Ё╟)C -¤░c)t-) o-¤Ё╟) -)suppo-¤░c)qr-)t-¤Ё╟)  -)loc-¤░c)5a-)l-¤Ё╟)  -) processin-¤░c)▓g-■0+) -)an-¤░c).d -(╤w analysis.- p)б -)App-¤░c)Il-) icat-¤░c)@i-) ons-■ЁW)C -)will-¤░c)9 -)have- 0╗)Z -) to be envi-¤░c)└r-)on-¤░c).m-)#ent-■ЁW)9 -)a-¤░c)g-)nostic-■ЁW)l -)and-¤Ё╟)E -)their-■░є)P -)pe-¤░c).r-)for-¤░c)0m-)#ance-■ЁW)Z -)will-¤░c)9 h-)*ave-■ЁW)C -)t-¤Ё╟) o-¤░c) -(wscale-■0+)a -)t-¤░c) o-■0+) -¤░c)t-) he-¤Ё╟). -)siz-¤░c)3e-■0+) -¤░c)o-)f-■0+)  -)the-¤░c)9 -)dat-¤░c)9a-■0+) -)s-¤░c)e-)ts-■0+)  -)an-¤░c).d-■0+) -)s-¤░c)i-) mul-¤░c)Ba-)tion-¤░c)Bs-).-■0+)  -¤░c)Mu-);ch-¤Ё╟), -)o-¤░c)f-■0+)  -)t-¤░c) h-)e-¤Ё╟) -)s-¤░c)o-)ftwar-¤░c)Ye-■0+) -)wr-¤░c),i-) tt-¤░c)e-)n-¤Ё╟) -)b-¤░c)y-■0+) -)astro-¤░c)\n-)omer-¤░c)^s -(1won-¤Ё╟). -) t-¤░c) h-)eir-¤░c). -) des-¤░c)Ck-)tops-¤░c)N -) i-¤░c) s-¤Ё╟) -) likel-¤░c)Gy-¤Ё╟) -) t-¤░c) o-¤Ё╟) -) tur-¤░c)0n-¤Ё╟) -) i-¤░c) n-)to-¤Ё╟)" -)the-¤░c)9 -)tech-¤░c)Nn-)o-¤░c) t-)urkeys-¤░c){ -) of-¤Ё╟)" -)the-¤░c)9 -)t-¤░c) i-) tl-¤░c)e-):-¤░c)  i-)t-¤Ё╟)  -)is s-¤░c)@i-) mply-¤░c)W n-)%ot-¤Ё╟)" -)wri-¤░c)5t-) te-¤░c)"n-¤Ё╟) -) t-¤░c) o-¤Ё╟) -) por-¤Ё╟)<t-¤░c)  -(awor- p)% -)*scale.
