Masana abwino, okondedwa okhala ku Khabrovsk!
Ndikufuna ndikuuzeni nthawi yayitali, ndikuyembekeza, yosangalatsa, komanso yothandiza, nkhani yosonkhanitsa "makompyuta apamwamba akumudzi" kuchokera pa bolodi la seva ya Dell, Nvidia Tesla K20 GPU ndi zomwe zidagulidwa apa ndi apo kuchokera kumasitolo osiyanasiyana a pa intaneti kapena masitolo apakompyuta mumzinda wanu.
Nkhaniyi inayamba pamene mnzanga wina wochita mapulogalamu, yemwenso ndi katswiri wa zakuthambo, anayamba kuphunzira za neural network. "Katswiri wawo wanthawi zonse" adasiya ntchito ndipo nkhaniyi idasindikizidwa pa "katswiri wapafupi kwambiri". Inenso sindine wopanga mapulogalamu, ndimangopanga "wailesi yokonza zida zamakompyuta (ndi) dipuloma yanga," kotero kusonkhanitsa mitundu yonse yazinthu zosangalatsa zamakompyuta ndi ntchito yosangalatsa komanso yosangalatsa kwa ine. Tsoka ilo, ndimagwira ntchito kudera lina.
Kuti ndikonze bwino ntchitoyi, ndidapanga mutu pabwalo la "Iron Ghosts of the Past", pomwe idakambidwa kwa nthawi yayitali. Poyamba panali lingaliro lopanda nzeru "kupanga 4-way SLI pa GTX 580 3Gb", yomwe idasintha pang'onopang'ono kukhala kumvetsetsa - muyenera kupanga seva! Mitengo ya ma boardboard a seva inali yokwera kwambiri mpaka ndidapeza kanema wosangalatsa pa Youtube wokhudza kukhazikitsidwa kwa bolodi la seva yaku China pa mapurosesa amtundu wa 2 omwe siwodziwika.
Nayi kanema:
Ndinakondwera kwambiri ndi mtengo wa bajeti wa dongosolo muvidiyoyi.
Komabe, kufunsana ndi anzanga odziwa zambiri omwe amagwira ntchito ndi ma seva aku China kunandikhutiritsa - "Sitikufuna chisangalalo cha China!" Malinga ndi ndemanga zawo, ma seva aku China anali osadalirika kwambiri. Ndipo ndinayamba kuyang'ana pa Avito pazosankha ndi matabwa a seva ya Dell. Ndili ndi ma laputopu awiri ochokera ku kampaniyi ndipo ndili ndi zabwino zokhazokha kuchokera kwa iwo. Ukadaulo wodalirika kwambiri.
Pa Avito ndinapeza Dell PowerEdge C6220 seva node board polankhulana ndi wogulitsa zomwe - adandiuza malo abwino kwambiri pomwe panali zofalitsa za momwe mmisiri wina adayambitsira bolodi lotere, . Ndipo panali ulalo wopita ku msonkhano waku America komwe zida zamphamvu zogwirira ntchito zidasonkhanitsidwa pama board oterowo..
Ndinawerenga mutu wonse kuyambira pachiyambi mpaka kumapeto, ndinasankha zolinga, zolinga ndi njira zopezera izo. Ntchitoyi idapangidwa motere: "Sonkhanitsani seva yapawiri-processor pa Dell PowerEdge C8220 node board yokhala ndi Tesla K10 kapena K20 GPU." Kusankhidwa kwa ma GPU apadera kudagwa pambuyo pokambirana ndi munthu yemwe dongosololi likusonkhanitsira - kukhala ndi "makhadi" omwe amatha kuwerengera nthawi yayitali ndikuwongolera zolakwika za kukumbukira kwa ECC, amatha kuzigwiritsa ntchito pazasayansi yake. ntchito, osati kungophunzitsa ma neural network. Zomwe adakondwera nazo kwambiri.
Kuti tikambirane ndi kulemba mbiri ya ndondomeko ya msonkhano pa "Iron Ghosts of the Past" forum, ndinapanga mutu wofanana, kumene ndinalembadi za ndondomekoyi ndikuyika zithunzi. .
Ntchitoyo idakhazikitsidwa ndipo ndidayamba kufunafuna zida. Pa nthawi yomwe zonsezi zidayamba, ndinali ndisanalembetse pa eBay ndipo poyamba zida zofunikira zidagulidwa ndi anzanga, omwe ndidawalipira ndalama zogulira ndi kutumiza. Pambuyo pake, inenso ndinalembetsa kumeneko ndikuyamba kugula mwachindunji, ngakhale kuti nthawi zina ndimayenera kupempha thandizo kwa omwe ali ndi akaunti pa Shopotam ndi ntchito zofanana. Sizinthu zonse zofunikira zomwe zimatumizidwa kuchokera ku USA kupita ku Russia.
Bokodi loyamba lomwe ndidagula ku eBay linali Dell PowerEdge C8220 0083N0. Malinga ndi zolemba za Dell, inali ya board version 1.2 ndipo inali ndi 3 PCI-E 16x slots. Pali awiri okhazikika pafupi ndi batani la mphamvu ndipo wachitatu kumbali ina ya bolodi siwofanana, chifukwa chotchedwa GPGPU riser, chomwe chinaphatikizidwa mu otchedwa Edge Slot.
Chithunzi cha bolodi, 0083N0 yemweyo, chithunzi kuchokera ku eBay.
Ndipo ichi ndi chithunzi changa, wolamulira amamangiriridwa pa bolodi kuti amvetsetse sikelo.
Pofika nthawi imeneyo, chokwera cha GPGPU mu Edge Slot yomweyo chinali chitafika kwa ine.
Nachi chithunzi chomwe chimalumikizidwa ndi malo ake okhazikika kuti ayesedwe.
Nthawi yomweyo, adaputala yamagetsi idagulidwa pa eBay, kuchokera ku ATX kupita ku cholumikizira chamagetsi cha C6100. Pali mitundu iwiri ya iwo yogulitsidwa pa eBay, 12 ndi 18 pini. Tikufuna zotsirizirazi, komanso mphamvu ya DC-DC kuti mutembenuzire +5VSB kuchokera ku ATX PSU kukhala +12VSB ya seva ya Dell. Ndipo zowonadi, cholumikizira chachikazi mu cholumikizira kuti muyike chodumphira chofunikira kuyambitsa bolodi ndikutulutsa chizindikiro cha PS_ON kuchokera pamenepo. Mwa njira, ili ndi mawonekedwe osagwirizana ndi 2.0 mm. Zachidziwikire, anyamata osimidwa amatha kumamatira screwdriver kapena msomali mwachindunji cholumikizira bolodi, koma ndimakonda kuchita chilichonse mwachilungamo.
Kuphatikiza apo, kuyesa kuyendetsa bolodi, tidagula Xeon E5-2604 V1 yotsika mtengo kwambiri ku Aliexpress ndi ndodo zokumbukira za DDR3 ECC REG zochokera ku eBay, zomwe zidagulitsidwa ngati n'zogwirizana ndi Dell PowerEdge C8220. Choyamba, ndidagwiritsa ntchito zoziziritsa kukhosi za Alpine 20 Plus C0 za LGA 2011, zomwe zidayenera kusinthidwa - m'mphepete mwake zomwe zidakhazikika pazikumbukiro zidasungidwa ndi chopukusira, mawaya amasupe adachotsedwa pazingwe zomangira, ndipo peyala ya mtedza. zokhomeredwa pa ulusi - kuti musamaze mozama kwambiri zomangirazo ndipo musathyole bolodi. Masiketi a seva a LGA 2011 adapangidwa mosiyana pang'ono ndi nthawi zonse, ndipo ulusi wa zomangira za heatsink uyenera kukhala waufupi. Mwa njira, zozizirazi zinagwira ntchito bwino, ngakhale kuti zinali zotayidwa.
Ndipo kotero, nthawi inafika pamene mapurosesa anafika, ndinajambula kuyika kwawo mu chithunzi ngati kukumbukira.
Ndipo apa pali zozizira zomwezo za Alpine aluminium zomwe zidayikidwa.
Kusonkhanitsa ndi kuyendetsa ndondomeko.
Mphamvu yanga yakale yokhulupirika ya Chieftek 550 W idalumikizidwa ndi kachitidweko, USB hub ya zida 4, zomwe zidaphatikiza kiyibodi, mbewa ndi flash drive yokhala ndi Ubuntu, wowerenga makhadi adalumikizidwa ndi cholumikizira chowerengera khadi la USB pa bolodi. chomwe ndidalumikiza chipangizo chomvera cha China cha USB, ndidalumikizanso chowunikira cha VGA ndi chingwe cholumikizira kudoko la 100 Mbit IPMI, lomwe limatchedwa Delicated-NIC. Pafupi nayo pali madoko awiri a 10Gbe omwe amagwiritsa ntchito mkuwa wopotoka nthawi zonse ndipo amathandizira kwathunthu netiweki ya 100/1000.
Dongosololi lidayambitsidwa mwanjira iyi ndipo zidapezeka kuti bolodi idayang'ana kukumbukira kwa nthawi yayitali kwambiri poyambira. Ndipo mu BIOS splash screen idadzitcha Dell DCS 6220.
Apa ndipamene ndimalizire gawo loyamba la nkhani yanga kuti ndisatope owerenga othokoza.
Lumikizani ku gawo 2:
