Molo emva kwemini, abahlali abathandekayo baseKhabrovsk!
Ndifuna ukukuxelela ixesha elide kwaye, ndiyathemba, elinomdla, kwaye mhlawumbi liluncedo, ibali lokudibanisa "i-supercomputer yelali" kwibhodi ye-node ye-Dell, i-Nvidia Tesla K20 GPU kunye nento eyathengwa apha naphaya kwiivenkile ezahlukeneyo ze-intanethi okanye kwi-intanethi. iivenkile zekhompyutha kwisixeko sakho.
Ibali laqala xa umdidiyeli wenkqubo umhlobo wam, okwasisazi ngeenkwenkwezi, waqala ukufunda ngothungelwano lwe-neural. βIngcaphephe yabo yexesha elizeleyoβ yayeka kwaye umcimbi wabethelelwa βkweyona ngcaphephe ikufutshaneβ. Mna ngokwam andingomcwangcisi wenkqubo, nje βumatshini werediyo wokulungisa izixhobo zekhompyuter (nge) idiploma yam,β ngoko ke ukudibanisa zonke iintlobo zezinto ezinomdla zekhompyuter ngumsebenzi onomdla nowonwabisayo kum. Ngelishwa, ndisebenza kwindawo eyahlukileyo.
Ukuyila ingxaki ngokucacileyo, ndidale isihloko kwiforum ethi "Iron Ghosts of the Past", apho kwaxoxwa khona ixesha elide. Ekuqaleni bekukho umbono ongekho ngqiqweni "ukwakha i-4-indlela ye-SLI kwi-GTX 580 3Gb", eyathi ngokuthe ngcembe iguqukele ekuqondeni - kufuneka wakhe iseva! Amaxabiso eebhodi zebhodi zeseva ebephezulu ngokugqithisileyo de ndadibana nevidiyo enomdla kwi-Youtube malunga nokusungulwa kwebhodi yeseva yaseTshayina kwiiprosesa ezi-2 ezingezizo ezisemgangathweni.
Nantsi ividiyo:
Ndonwabile ngakumbi ngexabiso lohlahlo lwabiwo-mali lwenkqubo kule vidiyo.
Nangona kunjalo, ukubonisana namaqabane anolwazi ngakumbi asebenzisana neeseva zaseTshayina kwandiqinisekisa- "Asifuni ulonwabo lwaseTshayina!" Ngokophononongo lwabo, iiseva zaseTshayina bezingathembekanga nje. Kwaye ndaqala ukukhangela kwi-Avito kwiinketho ngeebhodi ze-Dell server. Ndineelaptops ezimbini kule nkampani kwaye ndinezimvo ezintle kuphela ezivela kuzo. Itekhnoloji ethembekileyo kakhulu.
Kwi-Avito ndifumene ibhodi ye-node ye-Dell PowerEdge C6220 kwinkqubo yokunxibelelana nomthengisi wayo-wandicebisa indawo egqwesileyo apho kwakukho ukupapashwa malunga nendlela enye ingcibi eyasungula ibhodi enjalo, . Kwaye kwakukho ikhonkco kwiforum yaseMelika apho iindawo zokusebenzela ezinamandla zazidityaniswe kwiibhodi ezinjalo..
Ndafunda isihloko sonke ukususela ekuqaleni ukuya ekupheleni, ndagqiba kwiinjongo, iinjongo kunye neendlela zokuzifeza. Umsebenzi waqulunqwa ngolu hlobo lulandelayo: "Hlanganisa iseva yeprosesa ezimbini kwibhodi ye-node ye-Dell PowerEdge C8220 ene-Tesla K10 okanye i-K20 GPU." Ukhetho lweeGPU ezikhethekileyo lwawa emva kwengxoxo nomntu lowo inkqubo yayihlanganiselwa yena ngokwenene-ukuba "namakhadi" anokuthi enze izibalo zexesha elide ngokuchaneka kabini kunye nokulawulwa kweempazamo zememori ye-ECC, unokuzisebenzisa kwisayensi yakhe. imisebenzi, kwaye hayi nje ukuqeqesha iinethiwekhi ze-neural. Nto leyo eneneni wayonwabe kakhulu.
Ukuxoxa kunye nokurekhoda imbali yenkqubo yendibano kwiforum ethi "Iron Ghosts of the Past", ndenze isihloko esihambelanayo, apho ngokwenene ndabhala malunga nenkqubo kwaye ndathumela iifoto. .
Umsebenzi wamiselwa kwaye ndaqalisa ukukhangela amacandelo. Ngexesha xa yonke into yaqala, ndandingekabhalisi kwi-eBay kwaye ekuqaleni iindawo eziyimfuneko zathengwa ngabahlobo bam, endibahlawule iindleko zokuthenga nokuthumela. Kamva, nam ndabhalisa apho kwaye ndaqalisa ukuthenga ngokuthe ngqo, nangona ngamanye amaxesha kufuneka ndicele uncedo kwabo bane-akhawunti kwi-Shopotam kunye neenkonzo ezifanayo. Ayizizo zonke iinxalenye eziyimfuneko ezithunyelwa ngokuthe ngqo ukusuka e-USA ukuya eRashiya.
I-motherboard yokuqala endayithenga kwi-eBay yi-Dell PowerEdge C8220 0083N0. Ngokutsho kwamaxwebhu kaDell, yayiyeyebhodi yenguqulo 1.2 ene-3 PCI-E 16x slots. Kukho ezimbini eziqhelekileyo kufuphi neqhosha lamandla kunye neyesithathu kwelinye icala lebhodi alikho-standard, kuba ebizwa ngokuba yi-GPGPU riser, efakwe kwi-Edge Slot ebizwa ngokuba yi-Edge.
Ifoto yebhodi, efanayo 0083N0, ifoto evela eBay.
Kwaye lo ngumfanekiso wam, irula iqhotyoshelwe ebhodini ukuqonda isikali.
Ngelo xesha, isikhuphukeli se-GPGPU kwi-Edge Slot efanayo sasifikile kum.
Nantsi ifoto apho idityaniswe kwindawo yayo eqhelekileyo yovavanyo.
Ngelo xesha, i-adapter yamandla yathengwa kwi-eBay, ukusuka kwi-ATX ukuya kule C6100 isixhumi samandla. Kukho iintlobo ezimbini zazo ezithengiswa kwi-eBay, i-12 kunye ne-18 pin. Sifuna le yokugqibela, kunye ne-DC-DC yokunyusa ukujika + 5VSB ukusuka kwi-ATX PSU ukuya kwi-+12VSB ye-Dell server. Kwaye kunjalo, isidibanisi sowesifazane kwisidibanisi ukufaka i-jumper efunekayo ukuqalisa ibhodi kunye nokuphuma kwe-PS_ON uphawu kuyo. Ngendlela, inomgca woqhagamshelwano ongeyena umgangatho we-2.0 mm. Ewe, abafana abaphelelwe lithemba banokuncamathelisa i-screwdriver okanye isikhonkwane ngokuthe ngqo kwidibansi yebhodi, kodwa ndikhetha ukwenza yonke into ngokusemthethweni.
Ukongeza, ukuvavanya ukuqhuba ibhodi, sithenge i-Xeon E5-2604 V1 ebiza kakhulu kwi-Aliexpress kunye ne-DDR3 ECC REG yememori ye-eBay, eyathengiswa njengehambelana ne-Dell PowerEdge C8220. Okokuqala, ndasebenzisa ii-coolers ze-Alpine 20 Plus C0 ze-LGA 2011, ekwakufuneka ziguqulwe- imiphetho yazo eyayibekwe kwindawo yokubeka imemori yafakwa ngegrinder, iiwasha zasentwasahlobo zasuswa kwi-screws yokuqinisa, kunye nepere yamantongomane. ujijelwe kwimicu - ukuze ungajiki kwizikrufu ngokunzulu kwaye ungaphuli ibhodi. I-LGA 2011 iisokethi zomncedisi ziyilwe ngokwahlukileyo kunezinye eziqhelekileyo, kwaye imicu ye-heatsink screws kufuneka ibe mfutshane. Ngendlela, ii-coolers zasebenza kakuhle, nangona zaziyi-aluminium kuphela.
Kwaye ke, ixesha lafika xa iiprosesa zafika, ndathatha ukufakela kwabo kwifoto njengesikhumbuzo.
Kwaye nazi ii-coolers zeAlpine ezifanayo ezifakiweyo.
Inkqubo edityanisiweyo nesebenzayo.
Umbane wam omdala othembekileyo we-Chieftek 550 W uqhagamshelwe kwinkqubo, i-USB hub yezixhobo ezi-4, ezibandakanya ikhibhodi, imouse kunye ne-flash drive enoBuntu, umfundi wekhadi wayeqhagamshelwe kwisidibanisi somfundi wekhadi le-USB ebhodini. endiplage isixhobo somsindo se-USB yaseTshayina, ndaphinda ndaqhagamshela i-VGA esweni kunye nentambo yokubopha kwi-100 Mbit IPMI port, ebizwa ngokuba yi-Delicated-NIC. Ecaleni kwayo kukho amazibuko amabini e-10Gbe asebenza ngaphezulu kobhedu olujijekileyo rhoqo kwaye axhasa ngokupheleleyo inethiwekhi eqhelekileyo ye-100/1000.
Inkqubo yasungulwa kule fomu kwaye kwavela ukuba ibhodi ihlolisise imemori ixesha elide kakhulu ngexesha lokuqalisa. Kwaye kwi-BIOS splash screen yazibiza ngokuba yiDell DCS 6220.
Apha kulapho ndiya kuqukumbela khona inxalenye yokuqala yebali lam ukuze ndingakruquki abafundi abanombulelo.
