Tsiku labwino, okhala ku Khabrovsk! Ndipitiriza nkhani yanga posonkhanitsa "kompyuta yapamwamba m'mudzimo."
Ndiyamba gawo lachitatu ndikuthokoza anzanga omwe adandithandizira munthawi zovuta, kundilimbikitsa, kundithandiza ndi ndalama pothandizira bizinesi yodula iyi kwa nthawi yayitali komanso kuthandizira pogula zinthu zakumayiko akunja nthawi zina. Sindinathe kuzigula kwanuko. Mwachitsanzo, ngati kampani yomwe ikugulitsa magawo a seva ku USA kapena Canada sinatumize ku Russia. Popanda thandizo lawo lalitali komanso lokhazikika, kupambana kwanga kukanakhala kochepa kwambiri.
Komanso, chifukwa cha zopempha zawo, ndinayambanso ndikutsegula akaunti pa Youtube, ndinagula foni yamakono ya Lumia 640, yomwe ndimagwiritsa ntchito ngati kamera ya kanema, ndikuyamba kupanga mavidiyo ophunzitsa, onse okhudza kusonkhanitsa "kompyuta yaikulu ya m'mudzi" komanso pafupi. mbali zina ndi ntchito za moyo wakumudzi kwathu.
playlist "Village Supercomputer":
Amene akufuna owononga akhoza kuwawerenga, ngakhale kuti ndi bwino kuchita izi ndikuwerenga nkhani yanga kapena pambuyo pake.
Gawo lachiwiri la nkhani yanga linasokonezedwa ndi kulumikiza Tesla K20M, GT 610 ndi M.2 NVE SSD + disk array ku dongosolo. Mwa njira, ndi chiyani chinanso chomwe chili chabwino pa bolodi la Dell - ili ndi "shelufu ya disk" yomangidwa, ngakhale zida 6 zokha, ndipo RAID si "yopambana kwambiri padziko lapansi", koma mosiyana ndi anzake akunja. , imalumpha lamulo la TRIM pa SSD. Zomwe ndizofunikiranso ngati mumagwiritsa ntchito kwambiri ma SSD omwe si akatswiri.
Mwa njira, palinso mfundo imodzi yosangalatsa komanso yofunikira pa bolodi ili. Ma Radiators pa chipsets ndi otsika ndi zipsepse zazing'ono. Izi zimagwira ntchito bwino ngati bolodi ili mu rack yoyambirira, pomwe ma turbine amphamvu amawululira. Koma mukamagwiritsa ntchito bolodi padera, m'pofunika kuchotsa chomata cha pulasitiki kuchokera ku radiator pafupi ndi mipata yowonjezera, ndipo m'pofunika kuti m'malo mwake mutengepo mbali ina ndi radiator yoyenera kuchokera ku chipset cha bolodi lachikale chokhala ndi zipsepse zazikulu, chifukwa. Chip chomwe chili pansi pake chimatentha kwambiri pa bolodi.
Nditachotsa khadi la kanema pamakina, ndidayamba kusonkhanitsa chimango cha seva yanga; mu mtundu woyeserera, chilichonse chinali pa tepi yamagetsi, mabokosi a machesi ndi othandizira ena apulasitiki, koma kugwiritsa ntchito kwathunthu 24/7/365 njira iyi sinawonekere. zovomerezeka kwa ine. Zinali zofunikira kupanga chimango chabwino kuchokera ku ngodya ya aluminiyamu. Ndinagwiritsa ntchito ngodya za aluminiyamu zochokera ku Leroy Merlin, zomwe zinatumizidwa kwa ine ndi mnzanga wochokera ku dera la Moscow; mumzinda wapafupi wapafupi sanagulitsidwe kulikonse!
Kuphatikiza pa ngodya, mapangidwewo adagwiritsa ntchito zomangira ndi mtedza wa M5, zomangira za M3 ndi mtedza, ngodya zazing'ono za mipando, ma rivets a aluminium pamabowo 5 mm, mfuti ya rivet, hacksaw yachitsulo, screwdriver, kubowola zitsulo 5.0 mm. fayilo, screwdriver ya Phillips, zomangira zipi za chingwe ndi manja omwe samakula kuchokera pabulu.
Makona ankagwiritsidwa ntchito kumamatira thabwalo ku chimango ndi zinthu zina. Izi, ndithudi, zinawonjezera kutalika kwa dongosolo lonse, chifukwa bolodi linakwezedwa pamwamba kwambiri pamwamba pa ndege ya pansi pa chimango, koma ndinaganiza kuti izi ndizovomerezeka kwa ine. Sindinamenyere nkhondo gilamu iliyonse ya kulemera ndi millimeter kutalika; pambuyo pake, iyi si kompyuta yam'ndege momwe muyezo ndi "15 G mu nkhwangwa 3, kugwedeza mpaka 1000 G ndi kugwedezeka."
Bolodi imayikidwa, zokwera zimalowa mkati, adapter yokhala ndi SSD M.2 imalowetsedwamo.
Bolodi, SSD, risers ndi Tesla amaikidwa m'malo awo. DC-DC sinakhomedwebe m'malo mwake ndipo ikulendewera pamawaya kuseri kwazithunzi. Uwu ndi mtundu wa seva 1.0, ukadali pa Tesla K20M imodzi.
Apa DC-DC yalumikizidwa kale ndi chimango, pali mpango wawung'ono kumbuyo kwa bolodi pansi pa "michira" yamphamvu.
Ndipo iyi ndi dongosolo lomwe lasonkhanitsidwa kale, mawonekedwe apamwamba. Pamwamba pa Tesla pali ngodya ina yomwe ma SSD amasokonekera mbali ndi mbali, pamwamba pake pali khola la HDD, ndipo pamwamba pa chimango chomwe chimatseka chimango chimapachikidwa 850 W Thermaltek modular magetsi. Mphamvu zamagetsi ndizowoneka bwino, zamasewera, zowunikiranso za RGB, zomwe ndidazimitsa kuti zisagwe ngati mtengo wa Khrisimasi. Mphamvu yokhayo yamagetsi yokhazikika panthawiyo m'masitolo mumzinda wapafupi.
Mawonekedwe am'mbali a seva 1.0.
Kuwona kutsogolo kwa seva. Ndidapanga zolumikizira ndi zoyendetsa mbali imodzi, monga m'ma seva, kuti pazosintha zonse sindimayenera kutembenuzira dongosolo lonse mmbuyo ndi mtsogolo. Pa "bar yokhala ndi cutouts" pali tsinde lomwe lili ndi madoko awiri a USB 2.0, omwe ndidawalumikiza m'malo mwa owerenga makhadi, ndipo bolodi la adaputala la M.2 limakhomeredwa kumunsi kwake.
Apa mutha kuwona momwe DC-DC ndi bolodi zimatetezedwa, ngodya zomwe ndimakamba.
Onani kuchokera mbali inayo, momwe chokwera cha GPGPU, chomwe ndi EdgeSlot, chimalumikizidwa.
Chokwera pamakona apamwamba omwewo ndi mphamvu zowonjezera za GPGPU zomwe zidandigulira ine kudzera mu Whispers kuchokera ku America.
Makinawo adasonkhanitsidwa, makina ogwiritsira ntchito ndi madalaivala adayikidwa, CUDA Toolkit idakhazikitsidwa ...
Nayi kanema wamfupi wokhudza iye.
Mu mawonekedwe awa, dongosolo lomwe lili ndi Tesla K20M 5 GB linagwira ntchito kwa theka la chaka, pamene mnzanga wa zakuthambo anali kuwerengera ntchito zake. Kenaka anapita kutchuthi ndipo mwadzidzidzi anagwiritsa ntchito ma seva a Tesla K20X 6 GB kwa ma ruble 6000 anapezeka pa eBay, pogulitsidwa kuchokera ku data center ku England. Ndipo tinaganiza zosonkhanitsa mtundu wachiwiri wa "supercomputer" pogwiritsa ntchito 3 Tesla K20X.
Teslas adagulidwa, bolodi yachiwiri idagulidwa chimodzimodzi, okhawo adaganiza zosunga pobweretsa ndikusankha kutumiza ndi eBay. Yemwe adamutengera KU SPAIN ndikumupereka kwa munthu wina wakumanzere kwathunthu. Mkangano unatsegulidwa pa eBay, wogulitsa wochokera ku USA anandithandizira ndipo ndalamazo zinabwezedwa, ndipo malipiro achitatu adabwera kwa ine mu USPS yotsika mtengo koma yodalirika. Zida zina zosinthira zidafikanso ndipo nayi kanema wonena za kuyambika kwa msonkhano wa "village supercomputer" 2.0.
Kanema wa zida zosinthira za "makina" awa.
Kukhazikitsidwa kwa bolodi ndi zina.
Apa ndinayamba kusonkhanitsa chimango cha mtundu wachiwiri wa seva.
Tesla K20X wafika, kanema woyamba.
Kanema wamaphunziro wokhudza Tesla K20X, wokhudza kapangidwe ka khadi ndi kachitidwe kozizirirako, komanso kuphulika kwamadzi kuchokera ku GTX 780 Ti.
Kupitilira kanema wa Tesla K20X, ndidasanthula bolodi lake pa scanner, ngati wina angafunike mwadzidzidzi.
Mbali yakutsogolo yokhala ndi GPU chip.
Kumbuyo.
Monga tikuonera, Tesla K20, ngakhale zofanana "zambiri" ku GTX 780 GTX 780 ti GTX TITAN pa GK110 Kepler GPU, komabe sizigwirizana nazo malinga ndi bolodi ndi dongosolo lozizira. Ngati ndili ndi Quadro K5200 K6000 GK110 Kepler, ndiye ndikufanizira bolodi lake ndi bolodi la Tesla K20, koma mpaka pano ndilibe Quadros yomwe tatchulayi.
Ndipo apa pali kupitiliza kwa seva 2.0 kumanga
Apanso ozizira 1U ndi nkhono ndi zinthu zina zomwe zimafunikira pa seva yokhala ndi mphamvu zambiri kuposa yoyamba. Mwa njira, ndinayenera kusokoneza seva yoyamba kuti ndisonkhanitse yachiwiri, pamene mnzanga analibe kufunikira kowerengera.
Kasamalidwe ka chingwe pang'ono...
Ndipo Tesla yachiwiri imayikidwa m'malo mwake.
Koma apa ndinakumana ndi vuto lokhumudwitsa. Zinapezeka kuti dongosololi silingagwire mayunitsi 3 a Tesla K20. Mukayamba BIOS, cholakwika ichi chimatuluka ndipo ndizomwezo, Tesla yachitatu siigwira ntchito konse. Ngakhale kukonzanso BIOS kuti Baibulo 2.8.1 sikunathandize, kenako bolodi anatembenuka ku Dell DCS 6220 kukhala Dell C6220 2.8.1. pa Tesla ndi tepi kuti apange 8x - palibe chomwe chinathandiza. Ndinayenera kugwirizana ndi kasinthidwe ka 2 Tesla K20X + NVE SSD. Mwa njira, mu mtundu 2.0 wa seva, ma drive onse a SATA amakhala mudengu imodzi yaku China yokhala ndi zipinda 6. Tsopano pali awiri a Samsung 860 EVO 500 Gb + 4 terabyte Seagate. Ndinagula ma Samsung pa Ali pa 3600 iliyonse. Mawilo a OEM, koma amandikwanira.
Tsopano "supercomputer 2.0" yasonkhanitsidwa kwathunthu ndipo yakonzeka kugwiritsidwa ntchito.
Mwa zina, zida zogulira zida zachiwiri zidafika ndipo ndidasonkhanitsa yoyamba, nayi kanema wokhudza izi.
Ndipo ndikupempha owerenga kuti avotere choti achite ndi bolodi loyamba? Ndi zinthu ziti zosangalatsa zomwe zingasonkhanitsidwe potengera izo? Kapena ngati wina akufuna kugula ngati Tesla K20M ndi K20X yokhala ndi zoziziritsa kukhosi kapena zopanda nkhono - ndakonzeka, lembani.
Nayi nkhani yotere, ndikuyembekeza kuti idzakhala yosangalatsa komanso yothandiza kwa owerenga okondedwa.
PS: Kwa iwo omwe anali ndi kuleza mtima kuti awerenge mpaka kumapeto - lembetsani ku tchanelo changa pa YouTube, ndemanga, monga / kusakonda - izi zindilimbikitsa kuti ndiwonjezere zofalitsa ndikujambula makanema atsopano ophunzirira.
