Sawubona, bahlali abathandekayo baseKhabrovsk!
Ngifuna ukukutshela indaba ende futhi, ngethemba, ethakazelisayo, futhi mhlawumbe ewusizo, yokuhlanganisa "i-supercomputer yasesigodini" ebhodini le-node ye-Dell, i-Nvidia Tesla K20 GPU kanye nalokho okwathengwa lapha nalapha ezitolo ezihlukahlukene ze-intanethi noma izitolo zamakhompyutha edolobheni lakho.
Indaba yaqala lapho umngane wami ongumhleli wezinhlelo, naye oyisazi sezinkanyezi, eqala ukufunda amanethiwekhi emizwa. “Ungcweti wabo wesikhathi esigcwele” wayeka futhi inkinga yaphinwa “kuchwepheshe oseduze”. Mina ngokwami angiyena umhleli, "umakhenikha werediyo wokulungisa imishini yekhompiyutha (nge) idiploma yami," ngakho ukuhlanganisa zonke izinhlobo zehardware yekhompyutha ezithakazelisayo kuwumsebenzi othakazelisayo nojabulisayo kimi. Ngeshwa, ngisebenza endaweni ehlukile.
Ukuze ngenze umsebenzi ngokucace kakhudlwana, ngakha isihloko esithangamini esithi “Izipoki Zensimbi Zasesikhathini Esidlule,” lapho kwaxoxwa khona isikhathi eside. Ekuqaleni kwakunombono ongenalutho "wokwakha i-SLI ye-4-way ku-GTX 580 3Gb", eyashintsha kancane kancane yaba ukuqonda - udinga ukwakha iseva! Izintengo zamabhodi omama weseva beziphezulu ngendlela exakile ngaze ngahlangana nevidiyo ethokozisayo ku-Youtube mayelana nokwethulwa kwebhodi leseva yesiShayina kumaphrosesa amafomethi angajwayelekile angu-2.
Nansi ividiyo:
Ngijabule kakhulu ngenani lesabelomali sohlelo kule vidiyo.
Nokho, ukubonisana namaqabane anolwazi oluthe xaxa ayesebenzelana namaseva aseShayina kwangiqinisekisa - “Asiyidingi injabulo yamaShayina!” Ngokusho kokubuyekezwa kwabo, amaseva aseShayina abevele engathembeki ngendlela emangalisayo. Futhi ngaqala ukubheka ku-Avito ngezinketho ngamabhodi weseva ye-Dell. Nginamakhompyutha aphathekayo amabili avela kule nkampani futhi nginokuvela okuhle kuphela okuvela kuwo. Ubuchwepheshe obuthembekile kakhulu.
Ku-Avito ngathola ibhodi le-node ye-Dell PowerEdge C6220 ngesikhathi sokuxhumana nomthengisi lapho - wangiphakamisa isayithi elihle kakhulu lapho kwakukhona ukushicilelwa mayelana nendlela ingcweti eyodwa eyethula ngayo ibhodi elinjalo, . Futhi kwakukhona isixhumanisi senkundla yaseMelika lapho izindawo zokusebenza ezinamandla zazihlanganiswe emabhodini anjalo..
Ngasifunda sonke isihloko kusukela ekuqaleni kuze kube sekugcineni, nganquma ngezinhloso, izinjongo nezindlela zokuzifinyelela. Umsebenzi wakhiwe ngale ndlela elandelayo: "Hlanganisa iseva esebenza kabili ebhodini le-node ye-Dell PowerEdge C8220 nge-Tesla K10 noma i-K20 GPU." Ukukhethwa kwama-GPU akhethekile kwehla ngemuva kwengxoxo nomuntu obekuhlanganiselwe yena uhlelo - enamakhadi "amakhadi" angakwazi ukwenza izibalo zesikhathi eside ngokunemba okuphindwe kabili nokulawula amaphutha ememori ye-ECC, angawasebenzisela isayensi yakhe. imisebenzi, hhayi nje ukuqeqesha amanethiwekhi emizwa. Okwamjabulisa kakhulu impela.
Ukuze sixoxe futhi sirekhode umlando wenqubo yomhlangano esithangamini esithi “Izipoki Zensimbi Zangaphambili”, ngakha isihloko esihambisanayo, lapho ngabhala khona ngempela ngenqubo futhi ngathumela nezithombe. .
Umsebenzi wamiswa futhi ngaqala ukucinga izingxenye. Ngesikhathi konke kuqala, ngangingakabhalisi ku-eBay futhi ekuqaleni izinsimbi eziyisipele ezidingekayo zathengwa abangane bami, engangikhokhela kubo izindleko zokuthenga nokuthumela. Kamuva, nami ngabhalisa lapho futhi ngaqala ukuthenga ngokuqondile, nakuba ngezinye izikhathi kufanele ngicele usizo kulabo abanama-akhawunti eShopotam nezinkonzo ezifanayo. Akuzona zonke izingxenye eziyisipele ezidingekayo ezithunyelwa ngokuqondile zisuka e-USA ziye eRussia.
I-motherboard yokuqala engayithenga ku-eBay kwakuyi-Dell PowerEdge C8220 0083N0. Ngokusho kwemibhalo kaDell, bekungokwebhodi yenguqulo 1.2 enezikhala ze-3 PCI-E 16x. Kukhona okubili njalo eduze kwenkinobho yamandla kanti eyesithathu ngakolunye uhlangothi lwebhodi ayiyona ejwayelekile, ebizwa ngokuthi i-GPGPU riser, eyayifakwe kulokho okubizwa ngokuthi i-Edge Slot.
Isithombe sebhodi, i-0083N0 efanayo, isithombe esivela ku-eBay.
Futhi lesi yisithombe sami, irula linamathiselwe ebhodini ukuqonda isikali.
Ngaleso sikhathi, isikhuphukeli se-GPGPU ku-Edge Slot efanayo sase sifikile kimi.
Nasi isithombe lapho ixhunywe khona endaweni yayo evamile ukuze ihlolwe.
Ngesikhathi esifanayo, i-adaptha yamandla yathengwa ku-eBay, kusukela ku-ATX kuya kulesi sixhumi samandla se-C6100. Kunezinhlobo ezimbili zazo ezithengiswa ku-eBay, izikhonkwane ezingu-12 nezingu-18. Sidinga okwakamuva, kanye ne-DC-DC boost ukuze siguqule i-+5VSB isuka ku-ATX PSU iye ku-+12VSB yeseva yakwaDell. Futhi-ke, isixhumi sowesifazane kusixhumi sokufaka i-jumper edingekayo ukuze uqalise ibhodi futhi ukhiphe isignali ye-PS_ON kuso. Ngendlela, ine-pitch yokuxhumana engajwayelekile engu-2.0 mm. Yiqiniso, abafana abaphelelwe yithemba bangakwazi ukunamathisela i-screwdriver noma isikhonkwane esixhunyweni sebhodi, kodwa ngincamela ukwenza yonke into ngokuziphatha.
Ngaphezu kwalokho, ukuze sihlole ukusebenzisa ibhodi, sithenge i-Xeon E5-2604 V1 eshibhe kunazo zonke kwa-Aliexpress kanye nezinti zememori ze-DDR3 ECC REG ezivela ku-eBay, ezithengiswe njengezihambisana ne-Dell PowerEdge C8220. Okokuqala, ngisebenzise ama-coolers e-Alpine 20 Plus C0 e-LGA 2011, okwakudingeka ashintshwe - imiphetho yawo eyayibekwe phezu kwezikhala zenkumbulo yafakwa ngegrinder, amawasha asentwasahlobo asuswa ezikulukweni zokubopha, kwafakwa ipheya lamantongomane. zijikijelwe emiculweni - ukuze zingakulufi izikulufu zijule kakhulu futhi ungaliphuli ibhodi. Amasokhethi weseva ye-LGA 2011 aklanywe ngokuhlukile kancane kunalawo avamile, futhi imicu yezikulufu ze-heatsink kufanele ibe mfushane. Ngendlela, ama-coolers asebenze kahle, naphezu kweqiniso lokuthi ayeyi-aluminium kuphela.
Futhi-ke, isikhathi safika lapho ama-processor efika, ngathwebula ukufakwa kwawo esithombeni njengesikhumbuzo.
Futhi nazi ama-coolers afanayo e-Alpine aluminium afakiwe.
Isistimu ehlanganisiwe futhi esebenzayo.
Ugesi wami omdala othembekile we-Chieftek 550 W wawuxhunywe ohlelweni, ihabhu le-USB lamadivayisi angu-4, okwakuhlanganisa ikhibhodi, igundane kanye ne-flash drive eno-Ubuntu, isifundi sekhadi sasixhunywe kusixhumi somfundi wekhadi le-USB ebhodini engixhume kulo idivayisi yomsindo ye-USB yaseShayina, ngiphinde ngaxhuma imonitha ye-VGA kanye nentambo yokunamathisela embobeni ye-IPMI engu-100 Mbit, ebizwa ngokuthi i-Delicated-NIC. Eduze kwayo kunezimbobo ezimbili ze-10Gbe ezisebenza phezu kwethusi elisontekile elivamile futhi elisekela ngokugcwele inethiwekhi evamile engu-100/1000.
Uhlelo lwethulwe ngaleli fomu futhi kwavela ukuthi ibhodi lihlole inkumbulo isikhathi eside kakhulu ngesikhathi sokuqalisa. Futhi esikrinini se-BIOS splash yazibiza nge-Dell DCS 6220.
Yilapho engizophetha khona ingxenye yokuqala yendaba yami ukuze ngingaciki abafundi ababongayo.
