Molo, bahlali baseKhabrovsk! Ndiza kuqhubeka nebali lam ngokudibanisa βikhompyutha enkulu ekwilali.β
Ndizakuqala icandelo lesithathu ngokuvakalisa umbulelo ongazenzisiyo kubahlobo bam abandixhasayo kumaxesha anzima, bandikhuthazayo, bandinceda ngemali ngokuxhasa eli shishini libiza imali eninzi ixesha elide kwaye bade bancedise ekuthengeni izinto ezivela phesheya kwiimeko apho. Andikwazanga ukuzithenga ekuhlaleni. Umzekelo, ukuba inkampani ethengisa iinxalenye zeseva e-USA okanye eCanada ayizange iyithumele eRashiya. Ngaphandle koncedo lwabo olude noluthe rhoqo, impumelelo yam ngeyayithobeke ngakumbi.
Kwakhona, ngenxa yezicelo zabo, ndathatha inyathelo ndavula iakhawunti kwi-Youtube, ndathenga i-smartphone endala ye-Lumia 640, endiyisebenzisa kuphela njengekhamera yevidiyo, kwaye ndaqala ukwenza iividiyo ezifundisayo, malunga nokuhlanganisa "i-supercomputer yedolophana" kunye malunga. eminye imiba kunye neeprojekthi zobomi belali yam.
Uluhlu lokudlala "I-Village Supercomputer":
Abo bafuna abaphangi banokuzifunda, nangona kunjalo kungcono ukwenza oku ngelixa ufunda ibali lam okanye nasemva koko.
Inxalenye yesibini yebali lam yaphazamiseka ngokudibanisa iTesla K20M, GT 610 kunye ne-M.2 NVE SSD + idisk array kwinkqubo. Ngendlela, yintoni enye into enhle ngale bhodi yeDell - ine "shelf yediski" eyakhelwe-ngaphakathi, nangona izixhobo ezi-6 kuphela, kwaye i-RAID ayiyona "eyona nto iyinkimbinkimbi emhlabeni", kodwa ngokungafaniyo nabalingane bayo bangaphandle. , itsiba umyalelo we-TRIM kwi-SSD. Eyona nto ibalulekileyo ukuba usebenzisa ngokungqongqo ii-SSD zeseva ezingezizo ezobuchwephesha.
Ngendlela, kukho inqaku elinomdla nelibalulekileyo malunga nale bhodi. I-Radiators kwii-chipsets ziphantsi kunye namaphiko amancinci. Oku kusebenza kakuhle xa ibhodi ikwirack yayo yoqobo, apho iiinjini zomoya ezinamandla ziyivuthela. Kodwa xa usebenzisa ibhodi ngokwahlukileyo, kuyimfuneko ukususa isincamathelisi seplastiki kwiradiyetha ekufutshane neendawo zokubeka, kwaye kuyacetyiswa ukuba utshintshe enye kude kunye nayo nayiphi na i-radiator efanelekileyo kwi-chipset ye-motherboard endala ene-fins enkulu, kuba I-chip ephantsi kwayo ishushu kakhulu ebhodini.
Emva kokuba ndisuse ikhadi levidiyo kwinkqubo, ndaqala ukuqokelela isakhelo seseva yam; kwinguqulo yovavanyo, yonke into yayikwiteyiphu yombane, iibhokisi zematshisi kunye nezinye izixhaso zeplastiki, kodwa ngokusetyenziswa ngokupheleleyo 24/7/365 olu khetho aluzange lubonakale. kwamkelekile kum. Kwakuyimfuneko ukwenza isakhelo esiqhelekileyo kwi-angle ye-aluminium. Ndasebenzisa iikona zealuminiyam ezivela kuLeroy Merlin, ezazithunyelwe kum ngumhlobo wam osuka kummandla waseMoscow; kwisixeko esikufuphi ndandingathengiswanga naphi na!
Ukongeza kwiikona, idizayini isetyenziswe i-M5 countersunk screws kunye namantongomane, i-M3 screws kunye namantongomane, iikona zefenitshala ezincinci, iirivets ze-aluminium kwimingxuma eyi-5 mm, i-rivet gun, i-hacksaw yesinyithi, i-screwdriver, i-5.0 mm drill yesinyithi; ifayile, i-screwdriver yePhillips, izibophelelo zentambo ye-zip kunye neengalo ezingakhuli ukusuka kwi-esile.
Iikona zazisetyenziselwa ukuncamathisela ibhodi kwisakhelo kunye nezinye izinto. Oku, ngokuqinisekileyo, yongeza ubude obuthile kwinkqubo yonke, kuba ibhodi yayiphakanyiswe phezulu kakhulu ngaphezu kwendiza ephantsi yesakhelo, kodwa ndagqiba ekubeni oku kwamkelekile kum. Khange ndilwele yonke igram yobunzima kunye ne-millimeter yobude; emva kwayo yonke loo nto, le ayisiyiyo ikhompyuter ekwibhodi yenqwelomoya apho umgangatho "uyi-15 G kwi-axes ezi-3, iyothusa ukuya kuthi ga kwi-1000 G kunye nokungcangcazela."
Ibhodi ifakwe, izinyusi zifakwe ngaphakathi, i-adapter ene-SSD M.2 ifakwe ngaphakathi.
Ibhodi, i-SSD, ii-rivers kunye neTesla zifakwe kwiindawo zazo. I-DC-DC ayikakrwitshwa endaweni kwaye ijinga kwiingcingo ezisemva kwezigcawu. Le yinguqulo yomncedisi 1.0, isekwiTesla K20M enye.
Apha i-DC-DC sele ifakwe kwisakhelo, kukho isikhafu esincinci kwicala elingasemva kwebhodi le-motherboard phantsi kwamandla "emisila".
Kwaye le yinkqubo esele idityanisiwe, imbono ephezulu. Ngaphezulu kweTesla kukho enye ikona apho iperi ye-SSD ikrwelwe ecaleni, ngaphezulu kwayo kukho ikheji ye-HDD, kwaye ngaphezulu kwesakhelo esivala isakhelo sixhoma i-850 W Thermaltek umbane wemodyuli. Umbane usefashonini, uyinto yokudlala, ene-RGB backlighting, endiyicimileyo ukuze ingaqhwanyazi njengomthi weKrisimesi. Unikezelo lwamandla kuphela lwemodyuli enamandla ngelo xesha kwiivenkile kwisixeko esikufuphi.
Imbono esecaleni yenguqulo ye-server 1.0.
Imboniselo yangaphambili yomncedisi. Ndenze iziqhagamshelo kunye needrive zokuqhuba kwicala elinye, njengeesistim zeseva, ukuze kuzo zonke ii-manipulations andikhange ndijike yonke inkqubo emva naphambili. Kwi-"bar ene-cutouts" i-screw stem kunye ne-USB 2.0 izibuko ezimbini, endizidibanise endaweni yomfundi wekhadi, kunye nebhodi ye-adapter ye-M.2 ifakwe kwindawo yayo ephantsi.
Apha ungabona indlela i-DC-DC kunye nebhodi ekhuselekile ngayo, iikona kanye bendithetha ngazo.
Jonga ukusuka kwelinye icala, indlela yokunyuka kwe-GPGPU, eyi-EdgeSlot, iqhotyoshelweyo.
Kwale ndawo iphakamileyo yokuphakama kwekona enamandla ongezelelweyo eGPGPU endithengelwe mna nge-Whispers evela eMelika.
Umatshini wahlanganiswa, inkqubo yokusebenza kunye nabaqhubi bafakwe, i-CUDA Toolkit yacwangciswa...
Nantsi ividiyo emfutshane malunga naye.
Kule fomu, inkqubo ene-Tesla K20M 5 GB isebenze isiqingatha sonyaka, ngelixa umhlobo wam weenkwenkwezi wayebala imisebenzi yakhe. Emva koko waya eholide kwaye ngokukhawuleza wasebenzisa iiseva ze-Tesla K20X 6 GB kwii-ruble ze-6000 zafunyanwa kwi-eBay, ezithengiswayo kwiziko ledatha eNgilani. Kwaye sagqiba ekubeni sihlanganise inguqulo yesibini ye "supercomputer" usebenzisa i-3 Tesla K20X.
I-Teslas yathengwa, i-motherboard yesibini yathengwa ngokufanayo, kuphela banquma ukugcina ekuhanjisweni kwaye bakhetha ukuhanjiswa nge-eBay. Ngubani owamsa e-SPAIN wamnikezela komnye umfana osekhohlo ngokupheleleyo. Ingxabano yavulwa kwi-eBay, umthengisi ovela e-USA wandixhasa kwaye imali yabuyiselwa, kwaye sele intlawulo yesithathu yafika kum kwi-USPS eqhelekileyo ebiza kodwa ethembekileyo. Ezinye iindawo ezisecaleni nazo zafika kwaye nantsi ividiyo malunga nokuqala kwendibano ye "village supercomputer" 2.0.
Ividiyo malunga neendawo ezisecaleni zalo "matshini" kakhulu.
Ukuqaliswa kwebhodi kunye nezinye iimpawu.
Apha ndaqala ukudibanisa isakhelo senguqulelo yesibini yomncedisi.
I-Tesla K20X ifikile, ividiyo yokuqala.
Ividiyo yemfundo malunga neTesla K20X, malunga nokuyila kwekhadi kunye nenkqubo yokupholisa, kunye ne-bummer kunye nebhloko yamanzi esuka kwi-GTX 780 Ti.
Ukuqhubela phambili kwevidiyo malunga neTesla K20X, ndaskena ibhodi yayo kwiskena, ukuba kukho umntu ofuna ngokukhawuleza.
Icala langaphambili kunye ne-GPU chip.
Ngasemva.
Njengoko sibona, i-Tesla K20, nangona ifana "ngemigaqo ngokubanzi" kwi-GTX 780 GTX 780 ti GTX TITAN kwi-GK110 Kepler GPU, nangona kunjalo ayihambelani nabo ngokwebhodi kunye nenkqubo yokupholisa. Ukuba ndine-Quadro K5200 K6000 GK110 Kepler, ngoko ndiya kuthelekisa ibhodi yayo kunye nebhodi yeTesla K20, kodwa okwangoku andinayo i-Quadros ekhankanywe ngasentla.
Kwaye nantsi ukuqhubeka komncedisi 2.0 ukwakha
Kwakhona ii-coolers ze-1U ezinemingxuma kunye nezinye izinto ezifunekayo kumncedisi onamandla angaphezu kweyokuqala. Ngendlela, kwafuneka ndiqhawule iseva yokuqala ukuze ndihlanganise eyesibini, ngelixa umhlobo wam wayengenaso isidingo esiphuthumayo sokubala.
Ulawulo lwentambo encinci...
Kwaye iTesla yesibini ifakwe kwindawo yayo.
Kodwa apha ndidibene nebham ekhubekisayo. Kwavela ukuba inkqubo ayikwazi ukuphatha iiyunithi ze-3 Tesla K20. Xa uqala i-BIOS, le mpazamo iyavela kwaye yiyo, iTesla yesithathu ayisebenzi konke konke. Kwanokuhlaziya i-BIOS kwinguqulo ye-2.8.1 ayizange incede, emva koko ibhodi yajika ukusuka kwi-Dell DCS 6220 ibe yi-Dell C6220 2.8.1. kwi-Tesla nge-tape ukubenza i-8x - akukho nto yanceda. Kwafuneka ndifikelele kwimimiselo yokucwangciswa kwe-2 Tesla K20X + NVE SSD. Ngendlela, kwinguqulo ye-2.0 yomncedisi, zonke iidrive ze-SATA zihlala kwibhasikithi enye yaseTshayina kunye namagumbi ama-6. Ngoku kukho iperi ye-Samsung 860 EVO 500 Gb + 4 terabyte Seagate. Ndithenge iiSamsung kuAli nge3600 enye. Amavili e-OEM, kodwa ayandifanela.
Ngoku i-"supercomputer 2.0" ihlanganiswe ngokupheleleyo kwaye ilungele ukusetyenziswa.
Kweminye imiba, iindawo ezisecaleni ezithengelwe inkqubo yesibini zafika kwaye ndabuyisela eyokuqala, nantsi ividiyo malunga nayo.
Kwaye ndimema abafundi ukuba bavote malunga nokuba benze ntoni ngebhodi yokuqala? Ziziphi izinto ezinomdla ezinokuqokelelwa ngokusekelwe kuyo? Okanye ukuba umntu ufuna ukuyithenga njengeTesla K20M kunye ne-K20X kunye okanye ngaphandle kwe-snail coolers - ndilungile, bhala.
Nali ibali elinjalo, ndiyathemba ukuba liya kuba nomdla kwaye libe luncedo kubafundi abathandekayo.
P.S.: Kwabo babenomonde wokufunda kude kube sekupheleni - bhalisela ijelo lam kuYouTube, izimvo, izinga lokuthanda/ukungathandi-oku kuya kundikhuthaza ukuba ndiqhubeke nopapasho kunye nokufota iividiyo ezintsha zemfundo.
