Kev Ua Haujlwm Zoo Tshaj Lij (HPC) yog lub peev xwm los ua cov ntaub ntawv thiab ua cov lej yooj yim ntawm qhov nrawm, nws yog daim ntawv thov "Supercomputers" los daws teeb meem uas yog loj heev rau cov khoos phis tawj lossis yuav siv sijhawm ntev heev los ua kom tiav. Top500 yog cov npe, uas tau tshaj tawm ob zaug hauv ib xyoos, thiab nyob rau qee qhov ntawm cov khoos phis tawj nrawm tshaj plaws, muaj zog tshaj plaws hauv ntiaj teb. Lub teb chaws thiab cov koom haum loj siv ntau lab hauv cov peev txheej kom muaj cov kab ke no nce thiab ua haujlwm rau tus kws tshawb fawb los txhawb lub xeev cov thev naus laus zis thev naus laus zis thiab daws teeb meem nyuaj.

Ntau xyoo dhau los, khoos phis tawj siv los txhim kho lawv cov kev ua tau zoo los ntawm kev ua kom nrawm dua ntawm cov txheej txheem. Tom qab peb ntsib qhov kev qeeb hauv txoj hauv kev no, cov neeg tsim khoom tau txiav txim siab tias txuas ntxiv kev ua haujlwm ntawm lub khoos phis tawj, ntau lub cores (lossis cov lej suav) yuav tsum tau ntim ua ke. Kev sib sau ua ke ntawm ntau cov peev txheej suav thiab cov txheej txheem los tswj cov peev txheej no yog qhov peb hu ua "parallelism" hauv computer science. Muaj ntau lub cores ua ntau txoj haujlwm zoo li yog txoj hauv kev zoo los txhim kho kev ua haujlwm ntawm lub khoos phis tawj … tab sis, qhov no qhib cov lus nug loj: peb yuav siv cov peev txheej no kom zoo dua li cas?

Cov lus nug no tau ua kom tus kws tshawb fawb computer tsis khoom, muaj ntau txoj hauv kev los qhia lub khoos phis tawj yuav ua li cas, muaj ntau txoj hauv kev los qhia ntau lub khoos phis tawj yuav ua li cas. Txoj haujlwm no tsom mus txhim kho lub platform uas muaj nqis uas txhua tus tuaj yeem sim nrog lub tshuab ua haujlwm zoo, sim cov qauv uas twb muaj lawm los thov hauv koj tus kheej cov phiaj xwm, txhim kho txoj hauv kev tshiab thiab muaj tswv yim los daws teeb meem kev suav lossis tsuas yog siv nws los qhia rau lwm tus txog computer. Peb cia siab tias koj tuaj yeem txaus siab ua haujlwm nrog DEMAC ntau npaum li peb muaj.

DEMAC

Delaware Modular Assembly Cluster (DEMAC) yog qhov nthuav dav nthuav dav ntawm cov kab ke (cov khoos phis tawj loj dua) thiab txheej 3Dprinted thav ntawv txhawm rau kaw cov laug cam thiab kho vajtse ntxiv uas muab lub zog, txias thiab nkag mus rau network.

Txhua lub cuab yeej lossis cov txheej txheem teeb tsa yog lub khoos phis tawj me, Parallella Board uas suav nrog cov peev txheej ntawm ob tus tub ntxhais siv ARM processor, 16-core coprocessor hu ua Epiphany thiab ib qho FPGA uas tau hloov pauv nrog qhov ua tiav qhib qhov chaw. Lub roob yog lub tsev tsim ua 3D-luam ntawv thav duab uas tso cai rau tus nqi qis thiab txhim kho tau. Nws tau tsim los kom haum 4 chav ntawm tus qauv loj me me (zoo li cov uas koj pom hauv chav computer servers).

Cov lus qhia no suav nrog:
