Masikati akanaka, vanodiwa vagari veKhabrovsk!
Ndinoda kukuudza kwenguva refu uye, ndinovimba, inonakidza, uye pamwe inobatsira, nyaya yekuunganidza "supercomputer yemumusha" kubva kuDell server node board, Nvidia Tesla K20 GPU uye zvakatengwa pano neapo kubva kuzvitoro zvakasiyana siyana zvepamhepo kana mu. zvitoro zvemakombuta muguta rako.
Nyaya yakatanga apo shamwari yangu yepurogiramu, inovawo nyanzvi yenyeredzi, yakatanga kudzidza neural network. "Nyanzvi yenguva yakazara" yavo yakasiya uye nyaya yakaroverwa pa "nyanzvi yepedyo". Ini pachangu handisi mugadziri wepurogiramu, kungoita "redhiyo mechanic yekugadzirisa michina yekombuta (ine) diploma yangu," saka kuunganidza marudzi ese emhando dzemakomputa anonakidza ibasa rinonakidza uye rinonakidza kwandiri. Sezvineiwo, ndinoshanda kune imwe nzvimbo.
Kuti ndinyatsogadzirisa basa racho, ndakagadzira musoro paforamu ye "Iron Ghosts of the Kare", kwayakakurukurwa kwenguva yakareba. Pakutanga pakanga paine zano risinganzwisisike "kuvaka 4-nzira SLI paGTX 580 3Gb", iyo yakashanduka zvishoma nezvishoma kuita kunzwisisa - unofanirwa kuvaka sevha! Mitengo yemasevha mabhodhi eamai yakakwira zvakanyanya kudzamara ndasangana nevhidhiyo inonakidza paYouTube nezve kutangwa kweChinese server board pane maviri asiri-standard fomati processors.
Heino vhidhiyo:
Ndakanyanya kufadzwa nemutengo webhajeti weiyo system muvhidhiyo iyi.
Nekudaro, kubvunzana nemakomuredhi ane ruzivo rwakawanda aibata nemasevha eChinese akandipwisa - "Hatidi mufaro weChinese!" Zvinoenderana neongororo yavo, maseva eChinese aingove asina kuvimbika. Uye ndakatanga kutarisa paAvito kune zvingasarudzwa neDell server mabhodhi. Ndine malaptops maviri kubva kukambani iyi uye ndine maonero akanaka chete kubva kwavari. Tekinoroji yakavimbika kwazvo.
PaAvito ndakawana Dell PowerEdge C6220 server node board mukuita kutaurirana nemutengesi wayo - akandikurudzira saiti yakanaka kwazvo pakanga paine chinyorwa nezvekuti imwe mhizha yakatanga sei bhodhi rakadaro, . Uye pakanga paine chinongedzo kuforamu yeAmerica uko nzvimbo dzekushanda dzine simba dzakaunganidzwa pamabhodhi akadaro..
Ndakaverenga musoro wese kubva pakutanga kusvika kumagumo, ndakasarudza pane zvinangwa, zvinangwa uye nzira dzekuzvizadzisa. Basa racho rakagadzirwa sezvizvi: "Unganidza maviri-processor server paDell PowerEdge C8220 node board ine Tesla K10 kana K20 GPU." Sarudzo yehunyanzvi maGPUs yakadonha mushure mekukurukurirana nemunhu ainyatso kuunganidzirwa system - aine "makadhi" anogona kuita maverengero enguva refu nekaviri nemazvo uye kutonga kweECC ndangariro zvikanganiso, aigona kuzvishandisa kune yake yesainzi. zviitiko, uye kwete zvekudzidzisa neural network. Zvaakafara chaizvo.
Kuti tikurukure uye kurekodha nhoroondo yegadziriro yegungano paforamu ye "Iron Ghosts of the Kare", ndakagadzira musoro unoenderana, kwandakanyatsonyora nezve maitiro uye ndakatumira mafoto. .
Basa rakaitwa uye ndakatanga kutsvaga zvikamu. Panguva iyo zvose zvakatanga, ndakanga ndisati ndava nekunyoresa paBay uye pakutanga zvikamu zvinodiwa zvakatengwa neshamwari dzangu, dzandakabhadhara mari yekutenga nekutumira. Gare gare, ini pachangu ndakanyoresa ipapo ndokutanga kutenga zvakananga, kunyange dzimwe nguva ndichifanira kukumbira rubatsiro kune avo vane maakaundi paShopotam nemamwe mabasa akafanana. Haasi ese anodiwa masipare parts anotumirwa zvakananga kubva kuUSA kuenda kuRussia.
Yekutanga mamaboard yandakatenga kubva kuBay yaive Dell PowerEdge C8220 0083N0. Zvinoenderana nezvinyorwa zveDell, yaive yebhodhi vhezheni 1.2 uye yaive ne3 PCI-E 16x slots. Kune maviri akajairwa padyo nebhatani remagetsi uye yechitatu kune rumwe rutivi rwebhodhi haisi-yakajairwa, kune iyo inonzi GPGPU riser, iyo yakabatanidzwa mune iyo inonzi Edge Slot.
Mufananidzo webhodhi, yakafanana 0083N0, mufananidzo kubva eBay.
Uye uyu ndiwo mufananidzo wangu, mutongi akasungirirwa pabhodhi kuti anzwisise chiyero.
Panguva iyoyo, siiri yeGPGPU mune imwechete Edge Slot yakanga yasvikawo kwandiri.
Heino pikicha iyo yakabatana nenzvimbo yayo yenguva dzose yekuedzwa.
Panguva imwecheteyo, adapta yemagetsi yakatengwa paeBay, kubva kuATX kuenda kune ino C6100 simba rekubatanidza. Kune mhando mbiri dzadzo dzinotengeswa paBay, 12 uye 18 pini. Isu tinoda iyo yekupedzisira, uye zvakare DC-DC inosimudzira kushandura +5VSB kubva kuATX PSU kuita +12VSB yeDell server. Uye zvechokwadi, chibatanidza chechikadzi mukubatanidza kuisa jumper inodiwa kuti utange bhodhi uye kuburitsa PS_ON chiratidzo kubva mairi. Nenzira, ine isina-standard yekuonana pitch ye2.0 mm. Ehe, vakomana vakapererwa vanogona kunamira screwdriver kana mbambo zvakananga mubhodhi rekubatanidza, asi ini ndaifarira kuita zvese zvehurumende.
Uye zvakare, kuti tiedze mhanyisa bhodhi, takatenga yakachipa Xeon E5-2604 V1 kubva kuAliexpress uye peya yeDDR3 ECC REG memory sticks kubva kuBay, iyo yakatengeswa seinowirirana neDell PowerEdge C8220. Chekutanga pane zvese, ndakashandisa Alpine 20 Plus C0 inotonhorera yeLGA 2011, iyo yaifanira kugadziridzwa - mipendero yavo yaizorora pandangariro slots yakaiswa neguyo, mawashi echitubu akabviswa kubva kune yekumisikidza screws, uye peya nzungu dzakaiswa. yakakwenenzverwa pashinda - kuitira kuti usapindire mukati ma screws zvakanyanya uye usatyora bhodhi. LGA 2011 server sockets yakagadzirirwa zvishoma zvakasiyana pane yakajairwa, uye tambo dzeheatsink screws dzinofanira kunge dziri pfupi. Nenzira, ma cooler akashanda zvakanaka, pasinei nokuti akanga ari aruminiyamu chete.
Uye saka, nguva yakasvika pakasvika ma processors, ndakatora kuisirwa kwavo mumufananidzo sechekuchengeta.
Uye heano mamwe maAlpine aluminium coolers akaiswa.
Yakasanganiswa uye inomhanya system.
Yangu yekare yakatendeka Chieftek 550 W magetsi akabatanidzwa kune sisitimu, USB hub yezvishandiso zvina, iyo yaisanganisira keyboard, mbeva uye flash drive neUbuntu, muverengi wekadhi akabatanidzwa kune chinongedzo che USB kadhi kuverenga pa bhodhi umo ndakadzvanya Chinese USB odhiyo mudziyo, ini zvakare ndakabatanidza VGA yekutarisisa uye chigamba tambo kune 4 Mbit IPMI port, iyo inonzi Delicated-NIC. Padivi payo pane maviri 100Gbe madoko anoshanda pamusoro penguva yakamonyoroka maviri emhangura uye anotsigira zvizere 10/100 network.
Iyo sisitimu yakatangwa mune iyi fomu uye zvakazoitika kuti bhodhi rakatarisa ndangariro kwenguva yakareba kwazvo panguva yekutanga. Uye muBIOS splash screen yakazvidaidza kuti Dell DCS 6220.
Apa ndipo pandichapedzisa chikamu chekutanga chenyaya yangu kuti ndisafinha vaverengi vanotenda.
Batanidza kune chikamu 2:
