Zuva rakanaka, vagari veKhabrovsk! Ndichaenderera mberi nenyaya yangu nekuunganidza "supercomputer mumusha."
Ini ndichatanga chikamu chechitatu nekutenda kwechokwadi kushamwari dzangu dzakanditsigira munguva dzakaoma, dzakandikurudzira, dzakandibatsira nemari nekutsigira iri bhizinesi rinodhura kwenguva yakareba uye kunyange kubatsira nekutenga zvinhu kubva kunze kwenyika mumatambudziko apo Handina kukwanisa kuzvitenga munharaunda. Semuenzaniso, kana kambani inotengesa maseva zvikamu muUSA kana Canada haina kungoitumira kuRussia. Pasina rubatsiro rwavo rwenguva refu uye rwenguva dzose, kubudirira kwangu kungadai kwakave kwakanyanyisa.
Zvakare, nekuda kwezvikumbiro zvavo, ndakatora danho ndikavhura account paYouTube, ndikatenga yekare Lumia 640 smartphone, yandinoshandisa chete sevhidhiyo kamera, ndokutanga kugadzira mavhidhiyo edzidzo, nezve kuunganidza "supercomputer yemumusha" uye nezve. zvimwe zvinhu uye zvirongwa zvehupenyu hwangu hwemumusha.
Playlist "Musha Supercomputer":
Avo vanoda vaparadzi vanogona kuzviverenga, kunyangwe hazvo zviri nani kuita izvi uchiverenga nyaya yangu kana kunyange mushure.
Chikamu chechipiri chenyaya yangu chakakanganiswa nekubatanidza Tesla K20M, GT 610 uye M.2 NVE SSD + disk array kune system. Nenzira, chii chimwe chakanaka pamusoro peiyi Dell board - ine yakavakirwa-mukati "dhisiki sherufu", kunyangwe yemidziyo mitanhatu chete, uye RAID haisi "yakaomesesa pasirese", asi kusiyana neayo ekunze nyanzvi dzekunze. , inosvetuka murairo weTRIM pane SSD. Izvo zvakakoshawo kana iwe ukashandisa zvakanyanya isiri-professional server SSDs.
Nenzira, kune zvakare imwe inonakidza uye yakakosha poindi pamusoro pebhodhi iri. Radiators pama chipsets akadzikira ane zvimbi zvidiki. Izvi zvinoshanda nemazvo kana bhodhi iri muraki yayo yepakutanga, uko maturbine ane simba anorifuridza. Asi kana uchishandisa bhodhi zvakasiyana, zvinodikanwa kubvisa pepa repurasitiki kubva kune radiator iri padyo nenzvimbo yekuwedzera, uye zvinokurudzirwa kutsiva iyo iri kure nechero radhiyadhi yakakodzera kubva kuchipset yebhodhi rekare rine zvimbi zvakakura, nekuti. iyo chip iri pasi payo inopisa zvakanyanya pabhodhi.
Ndabvisa kadhi revhidhiyo kubva muhurongwa, ndakatanga kuunganidza furemu yeserver yangu; muyedzo vhezheni, zvese zvaive pamatepi emagetsi, mabhokisi emitambo uye mamwe mapurasitiki anotsigira, asi kuti ishandiswe zvizere 24/7/365 sarudzo iyi haina kuita. zvinogamuchirika kwandiri. Zvaive zvakakodzera kugadzira furemu yakajairika kubva pakona yealuminium. Ndakashandisa makona ealuminium kubva kuLeroy Merlin, ayo akatumirwa kwandiri neshamwari kubva mudunhu reMoscow; muguta rangu riri pedyo ivo havana kutengeswa chero kupi zvako!
Pamusoro pemakona, dhizaini yakashandisa M5 countersunk screws uye nzungu, M3 screws uye nzungu, madiki fenicha makona, aluminium rivets ye5 mm maburi, rivet pfuti, hacksaw yesimbi, screwdriver, 5.0 mm chibooreso chesimbi, faira, Phillips screwdriver, cable zip tie uye maoko asingakure kubva pambongoro.
Makona aishandiswa kubatanidza bhodhi pafuremu uye zvimwe zvinhu. Izvi, hongu, zvakawedzera humwe hurefu kuhurongwa hwese, nekuti bhodhi rakasimudzwa zvakanyanyisa kumusoro kwepasi pasi peiyo furemu, asi ndakafunga kuti izvi zvakagamuchirwa kwandiri. Handina kurwira giremu rega rega rehuremu uye millimeter yehurefu; mushure mezvose, iyi haisi komputa yemundege ine mwero "15 G mumatemo matatu, inovhundutsa kusvika ku3 G uye kudedera."
Bhodhi rakaiswa, zvinosimudza zvinoputirwa mukati, iyo adapta ine SSD M.2 inoputirwa mukati.
Bhodhi, SSD, risers uye Tesla akaiswa munzvimbo dzavo. Iyo DC-DC haisati yaiswa panzvimbo uye yakarembera pawaya dziri kuseri kwezviitiko. Iyi iseva vhezheni 1.0, ichiri pane imwe Tesla K20M.
Pano iyo DC-DC yatove yakabatanidzwa kune furemu, kune kakafu kadiki parutivi kuseri kwebhodhi reamai pasi pesimba "miswe".
Uye iyi ndiyo yakatounganidzwa system, yepamusoro maonero. Pamusoro peTesla pane imwe kona umo maviri eSSD anokwizwa padivi, pamusoro pawo pane HDD cage, uye pamusoro pefuremu inovhara furemu inorembera 850 W Thermaltek modular magetsi. Iyo magetsi ndeye fashoni, yekutamba, ine RGB backlighting, iyo yandakadzima kuti isabwaire semuti weKisimusi. Iyo chete ine simba modular magetsi panguva iyoyo muzvitoro muguta riri pedyo.
Side maonero e server vhezheni 1.0.
Kumberi kwesevha. Ndakagadzira zvinobatanidza uye madhiraivha emadhiraivha kune rimwe divi, senge mumasevha masisitimu, kuti kune ese manipulations handina kufanira kushandura system yese kumashure nekudzoka. Pa "bar ine cutouts" inoputirwa tsinde ine mbiri USB 2.0 ports, iyo yandakabatanidza panzvimbo yemuverengi wekadhi, uye adapta board yeM.2 inokwenenzverwa kuchikamu chayo chepasi.
Pano iwe unogona kuona kuti iyo DC-DC nebhodhi inochengetedzwa sei, iwo makona chaiwo andanga ndichitaura nezvawo.
Tarisa kubva kune rimwe divi, kuti iyo GPGPU riser, iri EdgeSlot, yakabatanidzwa sei.
Iyo imwechete yekona yekumusoro inosimudza ine simba rekuwedzera reGPGPU yakatengerwa ini kuburikidza neWhispers kubva kuAmerica.
Muchina wakaunganidzwa, sisitimu yekushandisa uye madhiraivha akaiswa, iyo CUDA Toolkit yakagadziriswa ...
Heino vhidhiyo pfupi pamusoro pake.
Mune chimiro ichi, hurongwa neTesla K20M 5 GB yakashanda kwehafu yegore, apo shamwari yangu yekuongorora nyeredzi yakanga ichiverenga mabasa ake. Ipapo akaenda kuzororo uye kamwe kamwe akashandisa Tesla K20X 6 GB maseva e6000 rubles akawanikwa pa eBay, pakutengeswa kubva kune imwe nzvimbo yedata muEngland. Uye isu takasarudza kuunganidza yechipiri vhezheni ye "supercomputer" tichishandisa 3 Tesla K20X.
Teslas yakatengwa, yechipiri mamaboard yakatengwa zvakangofanana, ivo chete ndivo vakasarudza kuchengetedza pakutumira uye vakasarudza kuendesa neBay. Ndiani akamutora KUSPAIN ndokumutambidza kune mumwe mukomana wekuruboshwe zvachose. Kupokana kwakavhurwa paBay, mutengesi kubva kuUSA akanditsigira uye mari yakadzoserwa, uye yatove mubhadharo wechitatu wakauya kwandiri mune yakajairika inodhura asi yakavimbika USPS. Zvimwe zvakasara zvakasvikawo uye heino vhidhiyo nezve kutanga kwekuungana kwe "village supercomputer" 2.0.
Vhidhiyo pamusoro pezvikamu zvakasara zveiyi "muchina" chaiwo.
Kutangwa kwebhodhi uye zvimwe zvinhu.
Pano ndakatanga kuunganidza chimiro chechipiri vhezheni yeseva.
Tesla K20X yasvika, vhidhiyo yekutanga.
Vhidhiyo yekudzidzisa nezve Tesla K20X, nezve dhizaini yekadhi uye yekutonhodza system, uye bummer ine mvura block kubva kuGTX 780 Ti.
Kuenderera mberi kwevhidhiyo nezveTesla K20X, ndakatarisa bhodhi rayo pane scanner, kana paine munhu akaerekana achiida.
Rutivi rwemberi neGPU chip.
Backside.
Sezvatinoona, iyo Tesla K20, kunyangwe yakafanana "mumashoko akajairwa" kune GTX 780 GTX 780 ti GTX TITAN paGK110 Kepler GPU, zvisinei haienderane navo maererano nebhodhi uye kutonhora system. Kana ndine Quadro K5200 K6000 GK110 Kepler, ipapo ndichaenzanisa bhodhi rayo neTesla K20 board, asi kusvika ikozvino handina Quadros yataurwa pamusoro apa.
Uye heino kuenderera kwesevha 2.0 kuvaka
Zvakare 1U inotonhorera ine hozhwa uye zvimwe zvinhu zvinodiwa kune server ine simba rakawanda kupfuura rekutanga. Nenzira, ndaifanira kuparadzanisa sevha yekutanga kuti ndiunganidze yechipiri, nepo shamwari yangu yakanga isina chikonzero chekukurumidzira kuverenga.
A little cable management...
Uye yechipiri Tesla yakaiswa panzvimbo yayo.
Asi apa ndakasangana neshungu dzinogumbura. Zvakazoitika kuti sisitimu haigone kubata 3 Tesla K20 zvikamu. Paunotanga BIOS, kukanganisa uku kunobuda uye ndizvozvo, yechitatu Tesla haishande zvachose. Kunyangwe kuvandudza BIOS kushanduro 2.8.1 hazvina kubatsira, mushure mezvo bhodhi rakatendeuka kubva kuDell DCS 6220 kuita Dell C6220 2.8.1. paTesla ne tepi kuvaita 8x - hapana chakabatsira. Ini ndaifanira kuenderana nekugadziriswa kwe2 Tesla K20X + NVE SSD. Nenzira, muvhezheni 2.0 yeseva, ese maSATA madhiraivha anogara mubhasiki rimwe reChinese rine makamuri matanhatu. Ikozvino kune peya yeSamsung 6 EVO 860 Gb + 500 terabyte Seagate. Ndakatenga maSamsung paAli ne4 imwe neimwe. OEM mavhiri, asi anondikodzera.
Iye zvino "supercomputer 2.0" yakanyatso kuunganidzwa uye yakagadzirira kushandiswa.
Mune zvimwe zvinhu, zvikamu zvakatengwa zvechipiri system zvakasvika uye ndakaunganidza yekutanga kumashure, heino vhidhiyo nezvazvo.
Uye ini ndinokoka vaverengi kuti vavhote pane zvekuita nebhodhi rekutanga? Ndezvipi zvinhu zvinonakidza zvinogona kuunganidzwa zvichibva pazviri? Kana kuti kana mumwe munhu achida kuitenga seTesla K20M neK20X ine kana isina inotonhorera - ndagadzirira, nyora.
Heino nyaya yakadaro, ndinovimba inoshanduka kuva inofadza uye inobatsira kuvaverengi vanodiwa.
PS: Kune avo vaive nemoyo murefu wekuverenga kusvika kumagumo - nyoresa kuchiteshi changu paYouTube, taura, senge / kusada - izvi zvinondikurudzira kuti ndiwedzere kudhindwa uye kutora mavhidhiyo matsva edzidzo.
