Sawubona, bahlali baseKhabrovsk! Ngizoqhubeka nendaba yami ngokuhlanganisa “ikhompyutha enkulu endaweni.”
Ngizoqala ingxenye yesithathu ngokuzwakalisa ukubonga okuqotho kubangani bami abangeseka ezikhathini ezinzima, bangikhuthaza, bangisiza ngemali ngokuxhasa leli bhizinisi elibiza kakhulu isikhathi eside futhi basize nokuthengwa kwezingxenye ezivela phesheya ezimeni lapho Angikwazanga ukuzithenga endaweni. Isibonelo, uma inkampani ethengisa izingxenye zeseva e-USA noma e-Canada ivele ingazange iyithumele e-Russia. Ngaphandle kosizo lwabo olude noluvamile, ukuphumelela kwami bekuyoba okunesizotha kakhulu.
Futhi, ngenxa yezicelo zabo, ngathatha isinyathelo ngavula i-akhawunti ku-Youtube, ngathenga i-smartphone endala ye-Lumia 640, engiyisebenzisa njengekhamera yevidiyo kuphela, futhi ngaqala ukwenza amavidiyo afundisayo, kokubili mayelana nokuhlanganisa "i-supercomputer yasesigodini" futhi mayelana. ezinye izici namaphrojekthi wempilo yasesigodini sami.
Uhlu lokudlalayo “I-Village Supercomputer”:
Labo abafuna ama-spoiler bangakwazi ukuzifunda, nakuba kunjalo kungcono ukwenza lokhu ngenkathi ufunda indaba yami noma ngisho nangemva kwalokho.
Ingxenye yesibili yendaba yami iphazamisekile ngokuxhuma i-Tesla K20M, GT 610 kanye ne-M.2 NVE SSD + i-disk array ohlelweni. Kodwa-ke, yini enye enhle ngaleli bhodi le-Dell - "ineshalofu lediski" elakhelwe ngaphakathi, lamadivayisi ayi-6 kuphela, futhi i-RAID ayiyona "eyinkimbinkimbi kakhulu emhlabeni", kodwa ngokungafani nabalingani bayo bangaphandle abachwepheshile. , yeqa umyalo we-TRIM ku-SSD. Okubalulekile futhi uma usebenzisa kakhulu amaseva angewona ochwepheshe.
Ngendlela, kukhona futhi iphuzu elilodwa elithakazelisayo nelibalulekile mayelana naleli bhodi. Ama-radiator kuma-chipsets aphansi anamaphiko amancane. Lokhu kusebenza kahle uma ibhodi liku-rack yalo yasekuqaleni, lapho izinjini zomoya ezinamandla ziyiphephula. Kodwa uma usebenzisa ibhodi ngokwehlukana, kuyadingeka ukususa isitika sepulasitiki ku-radiator esiseduze nezikhala zokunweba, futhi kungakuhle ukuthi ushintshele kude nanoma iyiphi i-radiator efanelekile evela ku-chipset yebhodi lomama elidala elinamaphiko amakhulu, ngoba i-chip etholakala ngaphansi kwayo ishisa kakhulu ebhodini.
Ngemva kokukhipha ikhadi levidiyo ohlelweni, ngaqala ukuhlanganisa ifreyimu yeseva yami; enguqulweni yokuhlola, yonke into yayikuteyiphu kagesi, amabhokisi omentshisi nezinye izisekelo zepulasitiki, kodwa ukuze kusetshenziswe ngokugcwele 24/7/365 le nketho ayizange ibonakale. eyamukelekayo kimi. Kwakudingeka ukwenza ifreyimu evamile kusuka engeli ye-aluminium. Ngasebenzisa amakhona e-aluminium eLeroy Merlin, engangithunyelelwe umngane wami ovela esifundeni saseMoscow; edolobheni lakithi eliseduze ayengathengiswanga ndawo!
Ngaphezu kwamakhona, umklamo wasebenzisa i-M5 countersunk screws namantongomane, i-M3 screws namantongomane, amakhona amancane efenisha, ama-rivets e-aluminium emigodini engu-5 mm, isibhamu se-rivet, i-hacksaw yensimbi, i-screwdriver, i-5.0 mm drill yensimbi, ifayela, i-screwdriver ye-Phillips, othayi bekhebula zip nezingalo ezingaphumi embongolweni.
Amakhona ayesetshenziselwa ukunamathisela ibhodi ohlakeni nakwezinye izakhi. Lokhu, yiqiniso, kwengeze ukuphakama okuthile kulo lonke uhlelo, ngoba ibhodi laliphakanyiswe phezulu kakhulu ngaphezu kwendiza engezansi yohlaka, kodwa nginqume ukuthi lokhu kwamukelekile kimi. Angizange ngilwele igremu ngalinye lesisindo nemilimitha yobude; phela lena akuyona ikhompuyutha esendizeni lapho izinga elithi “15 G kuma-ax angu-3, ithusa kufika ku-1000 G nokudlidliza.”
Ibhodi lifakiwe, izikhuphukeli zifakwe ngaphakathi, i-adaptha ene-SSD M.2 ifakwe ngaphakathi.
Ibhodi, i-SSD, izikhuphukeli kanye ne-Tesla zifakwe ezindaweni zazo. I-DC-DC ayikakulunywa endaweni yayo futhi ilenga ezintanjeni ngemuva kwesigcawu. Lena inguqulo yeseva engu-1.0, namanje ku-Tesla K20M eyodwa.
Lapha i-DC-DC isivele inamathele kuhlaka, kukhona isikhafu esincane eceleni ngemuva kwebhodi lomama ngaphansi "kwemisila" yamandla.
Futhi lolu uhlelo oluvele luhlanganisiwe, ukubuka okuphezulu. Ngenhla kweTesla kunelinye ikhona lapho ipheya lama-SSD ajikijelwa eceleni, ngaphezu kwawo kunekheji ye-HDD, futhi phezu kohlaka oluvala uhlaka kulenga amandla emodular angama-850 W Thermaltek. Ugesi usemfashinini, ungowomdlalo, one-RGB backlighting, engayicisha ukuze ingacwayizi njengesihlahla sikaKhisimusi. Okuwukuphela kwamandla emodulayo enamandla ngaleso sikhathi ezitolo edolobheni eliseduze.
Ukubuka okuseceleni kwenguqulo yeseva engu-1.0.
Ukubuka kwangaphambili kweseva. Ngenze izixhumi namadrayivu amadrayivu ohlangothini olulodwa, njengakuzinhlelo zeseva, ukuze kukho konke ukukhohlisa bekungadingeki ngijikise lonke uhlelo emuva naphambili. “Kubha enama-cutouts” kufakwe isiqu ngezimbobo ezimbili ze-USB 2.0, engizixhume esikhundleni sesifundi sekhadi, futhi ibhodi le-adaptha le-M.2 lisikwe engxenyeni yalo engezansi.
Lapha ungabona ukuthi i-DC-DC kanye nebhodi kuvikelwe kanjani, wona kanye amakhona ebengikhuluma ngawo.
Buka ngakolunye uhlangothi, ukuthi isikhuphukeli se-GPGPU, okuyi-EdgeSlot, sinamathiselwe kanjani.
Isikhuphukeli sekhona esiphezulu esinamandla engeziwe e-GPGPU engithengelwe wona ngama-Whispers avela eMelika.
Umshini wahlanganiswa, isistimu yokusebenza kanye nabashayeli bafakwa, i-CUDA Toolkit yalungiswa...
Nansi ividiyo emfushane ngaye.
Kuleli fomu, uhlelo olune-Tesla K20M 5 GB eyodwa lusebenze isigamu sonyaka, kuyilapho umngane wami wesazi sezinkanyezi ebala imisebenzi yakhe. Khona-ke waya eholidini futhi ngokuzumayo wasebenzisa amaseva we-Tesla K20X 6 GB ama-ruble angu-6000 atholakala ku-eBay, ekuthengisweni kwesikhungo sedatha eNgilandi. Futhi sinqume ukuhlanganisa inguqulo yesibili ye "supercomputer" sisebenzisa i-3 Tesla K20X.
I-Teslas ithengiwe, i-motherboard yesibili yathengwa ngokufana ncamashi, kuphela banquma ukulondoloza ekulethweni futhi bakhetha ukulethwa nge-eBay. Ubani owamyisa ESPAIN wamnikeza insizwa ephiko kwesokunxele ngokuphelele. Ingxabano yavulwa ku-eBay, umdayisi ovela e-USA wangisekela futhi imali yabuyiselwa, futhi kakade inkokhelo yesithathu yafika kimi nge-USPS evamile ebizayo kodwa ethembekile. Ezinye izingxenye eziyisipele nazo zafika futhi nansi ividiyo mayelana nokuqala komhlangano we-"supercomputer yedolobha" 2.0.
Ividiyo emayelana nezingxenye ezisele zalo “mshini”.
Ukwethulwa kwebhodi nezinye izici.
Lapha ngaqala ukuhlanganisa uhlaka lwenguqulo yesibili yeseva.
I-Tesla K20X isifikile, ividiyo yokuqala.
Ividiyo efundisayo emayelana ne-Tesla K20X, mayelana nokuklanywa kwekhadi kanye nesistimu yalo yokupholisa, kanye nebhamu elinesivimba samanzi esivela ku-GTX 780 Ti.
Ukuqhubeka kwevidiyo mayelana ne-Tesla K20X, ngiskene ibhodi layo kusithwebuli, uma kukhona umuntu oyidinga ngokuzumayo.
Uhlangothi lwangaphambili olune-GPU chip.
Ngemuva.
Njengoba sibona, i-Tesla K20, nakuba ifana “ngokujwayelekile” ne-GTX 780 GTX 780 ti GTX TITAN ku-GK110 Kepler GPU, nokho ayihambisani nayo ngokwebhodi nohlelo lokupholisa. Uma ngine-Quadro K5200 K6000 GK110 Kepler, khona-ke ngizoqhathanisa ibhodi layo nebhodi le-Tesla K20, kodwa kuze kube manje anginayo i-Quadros eshiwo ngenhla.
Futhi nakhu ukuqhubeka kokwakhiwa kweseva 2.0
Futhi ama-coolers angu-1U aneminenke nezinye izinto ezidingekayo kuseva enamandla amakhulu kunawokuqala. Ngendlela, kwakudingeka ngihlukanise iseva yokuqala ukuze ngihlanganise eyesibili, kuyilapho umngane wami engenaso isidingo esiphuthumayo sokubala.
Ukuphathwa kwekhebula okuncane...
Futhi i-Tesla yesibili ifakwe endaweni yayo.
Kodwa lapha ngihlangabezane ne-bummer ecasulayo. Kuvele ukuthi uhlelo alukwazi ukuphatha amayunithi we-3 Tesla K20. Lapho uqala i-BIOS, leli phutha liyavela futhi yilokho, i-Tesla yesithathu ayisebenzi nhlobo. Ngisho nokubuyekeza i-BIOS ibe yinguqulo engu-2.8.1 akusizanga, okwathi ngemva kwalokho ibhodi lasuka ku-Dell DCS 6220 laya ku-Dell C6220 2.8.1. ku-Tesla nge-tape ukubenza babe ngu-8x - akukho okusizile. Kwadingeka ngivumelane nokucushwa kwe-2 Tesla K20X + NVE SSD. Ngendlela, kunguqulo 2.0 yeseva, wonke amadrayivu e-SATA ahlala kubhasikidi owodwa waseShayina onamagumbi ayi-6. Manje sekukhona ipheya ye-Samsung 860 EVO 500 Gb + 4 terabyte Seagate. Ngithenge ama-Samsung ku-Ali ngama-3600 lilinye. Amasondo e-OEM, kodwa ayangifanela.
Manje "i-supercomputer 2.0" isiqoqwe ngokuphelele futhi isilungele ukusetshenziswa.
Kwezinye izinto, izingxenye eziyisipele ezithengelwe uhlelo lwesibili zafika ngase ngihlanganisa eyokuqala emuva, nansi ividiyo ngakho.
Futhi ngimema abafundi ukuthi bavote ngokuthi benzeni ngebhodi lokuqala? Yiziphi izinto ezithakazelisayo ezingaqoqwa ngokusekelwe kuyo? Noma uma othile efuna ukuyithenga njenge-Tesla K20M ne-K20X enama-coolers omnenke noma ngaphandle kwawo - sengilungile, bhala.
Nansi indaba enjalo, ngithemba ukuthi izoba mnandi futhi ibe usizo kubafundi abathandekayo.
I-PS: Kulabo ababenesineke sokufunda kwaze kwaba sekugcineni - bhalisela isiteshi sami ku-YouTube, ubeke amazwana, uthanda/ungathandi - lokhu kuzongikhuthaza ukuthi ngiqhubeke nokushicilelwa nokuqopha amavidiyo amasha okufundisa.
