namaqonga CAD / GIS kufuneka aye GPU

Abo bethu abasebenzisa izicelo zemifanekiso, sihlala silindele ukuba iikhomputha zinememori efanelekileyo yokusebenza. Kule nkqubo, iiprogram ze-CAD / ze-GIS zihlala zibuzwa okanye zilinganiselwe ngokwexesha elithathayo ukwenza imisebenzi yemihla ngemihla njenge:

  • Uhlalutyo lwendawo
  • Ukulungiswa kunye nokubhaliswa kwemifanekiso
  • Ukuthunyelwa kwedatha enkulu
  • Ulawulo lweenkcukacha ngaphakathi kwe-geodatabase
  • Iinkcukacha zeenkonzo

I-PC yendabuko ayitshintshanga kakhulu kwiminyaka yamuva, ngokwe-RAM, idiski enzima, imemori yemifanekiso kunye nempawu eziye zanda; kodwa ingqiqo yokusebenza ye-CPU igcine isakhiwo sayo sokuqala (Yingakho siqhubeka simbiza ngeCPU). Kwaye kwaba yintlekele yokuba njengoko amaqela akhula amandla, iiprogram zibulala ukulindela kwabo ngokuyila ukutshisa i-new potential.

njenge-duus-gpu-khadi

Ngokomzekelo, (kunye nomzekelo kuphela) Xa abasebenzisi ezimbini zibekwe ngelo xesha phantsi kweemeko ezifanayo izixhobo kunye data, omnye AutoCAD 2010 enye kunye Microstation V8i, kulayishwa 14 eyi imifanekiso, ifayile parcelario iipropati 8,000 kunye uqhagamshelo kwiziko ledatha lwendawo Oracle, sizibuza yona umbuzo:

Yintoni enye yezo zibini, ukuze ungagqithisi umshini?

Impendulo ayikho emitsha, yindlela nje le nkqubo iphuhliswa ngayo, kuba akusiyo imeko nge-AutoDesk Maya, eyenza izinto ezininzi zobuqili kwaye zenze ngcono. Indlela yokuxhaphaza i-PC iyafana (ngoku kubekwe kwimeko yeenkqubo ezimbini), kwaye ngoku ngoku sibadubula iiprogram, kuba sihlala kuzo ukusebenza, kwaye zininzi. Ngaloo ndlela, ezinye iikhomputha ziyaziwa ngokuba yi-PC zendalo, izixhobo zokusebenza okanye amaseva; kungekhona ngenxa yokuba bangomnye umbala, kodwa ngenxa yindlela ababonelela ngayo ukuqhuba iinkqubo eziphezulu zokusetyenziswa kwi-design design, ukucutshungulwa kwevidiyo, ukuphuhliswa kwezicelo, imisebenzi yeseva kunye nathi, ukusebenza kunye nedatha yendawo.

I-CPU encinane, i-GPU eninzi

Eyona ebalaseleyo neenguqu kutshanje eziye zenzeke sesakhiwo iiPC ligama yavela GPU (Process Unit Graphics), ukufumana imisebenzi engcono ikhompyutha, ngokwenza imisebenzi kakhulu kwimisebenzi ezincinane ngaxeshanye, ngokudlulisela ulawulo ye-CPU (iCentral Process Unit), amandla akhe okudlala adlala phakathi kweenguqulelo ze disk, imemori ye-RAM, imemori yevidiyo kunye nezinye iinkcukacha (a baninzi abanye).

Amakhadi eemifanekiso ayenziwanga ukwandisa imemori yevidiyo, kodwa bona ngokwabo baquka iprojekthi equlethe amakhulu amabhola adibeneyo ukulungiselela iinkqubo ezifanayo. Bahlala benalo (ngaphezulu okanye ngaphantsi), kodwa inzuzo yile ndlela kukuba aba bakhiqizi banikezela ukuzakhela okuvaliweyo (phantse) ukwenzela ukuba abaphuhlisi beefowuni banokuqwalasela ubukho bekhadi lala manzi kwaye baxhaphaze amandla abo. Umagazini wePC kule nyanga kaJanuwari ukhankanya iinkampani ezifana ne-nVidia, ATI kunye nabanye kubandakanyeka kumanyano VulaCL

Ukuqonda umahluko phakathi kwe-CPU kunye ne-GPU, nantsi ndibhekisela kumzekeliso:

CPU, yonke indawo, ufana nomasipala onento yonke ephakathi, enesicwangciso sezidolophini, uyazi ukuba kufuneka ilawulwe ukukhula kwayo kodwa ayikwazi ukulawula nakwizakhiwo ezintsha eziphula imithetho. Kodwa kunokuba concessioning le nkonzo ukuze lweshishini yabucala, umi kubangelwa indima, abantu abazi bambombozelayo malunga ummelwane lowo uthatha ecaleni, kwaye isixeko desordenándose yonke imihla.

Uxolo, akazange akhulume ngodolophu wakho, uthetha nje ngomzekeliso we-CPU, apho le nxalenye yeCandelo leNkcazo (kwimeko yeWindows) kufuneka yenze iqela lenze kwiinkqubo ezifana nale:

  • Iinkqubo ezisebenza xa iWindows iqalisa, njenge-Skype, Yahoo Messenger, iAntivirus, i-Java injini, njl. Bonke abasebenzisa inxalenye yememori yomsebenzi kunye neyona nto ibalulekileyo ngaphandle kohlobo olungadingekile ngaphandle kokuba beguqulwa yi-msconfig (into endiyihoyileyo).
  • Iinkonzo eziqhubayo, eziyingxenye ye-Windows, iinkqubo eziqhelekileyo ezisetyenziswayo, ii-hardware ezixhunyiwe okanye ezinye ezikhishiwe kodwa zishiywa ziqhuba. Ezi zinto ziqheleke phambili ziphezulu / eziphezulu.
  • Iinkqubo ezisetyenzisiweyo, ezitya indawo ephezulu. Sivakalelwa sisantya sokuphumelela kwisibindi kuba siqalekisa ukuba ayenzi ngokukhawuleza nangona ineqela eliphezulu lokusebenza.

Kwaye nangona iWindows isebenza ngayo, iinkqubo ezinjengeenkqubo ezininzi ezivulekileyo, ukufaka okanye ukukhenxisa ngokungenakuphikelela, izihloko ezingadingekile ezibonakalayo iipintones, basenza sinetyala lokungasebenzi kwempahla.

Kwenzeka ke ngoko, ukuba xa siqala inkqubo yezo zikhankanywe ekuqaleni, umprosesa uya kuba ukuphazamisa ikhokoni lijonge ukubeka phambili phambili kwezinye iinkqubo ezisetyenziswayo. Izinketho zakhe ezimbalwa zokwenza ngcono imemori ye-RAM, imemori yevidiyo (edlalwa rhoqo), ukuba kukho imifanekiso yekrafikethi yokufumana into ethile, kuxhomekeke kuhlobo lwe-hard drive kunye nezinye izinto ezincinci, i-moan plaan mayingaphantsi.

GPU, iinkqubo ezifanayo, kunjengoko umasipala anquma ukulungiswa kwempahla, ukunikezelwa kwemvume okanye ukufihla loo nto izinto ezingenakufikelela, nokuba ngaba zinkulu iinkqubo zithunyelwa kwimisebenzi emincinci. Ngaloo ndlela, ngokusekelwe kwimimiselo yangoku, inkampani yangasese inikwe indima yokubeka iliso ukuphulwa okuthile ngendlela ethile. Ngenxa yoko (mzekelo nje), ummi unokuzalisekisa loo mihlali enomdla wokuxelela iimbambo kummelwane othabatha inja shit kwinqanaba layo, elakha udonga ethatha inxalenye yendlela, ukupaka imoto yakho ngendlela engafanelekanga, njl njl. Inkampani iphendula ikhwelo, iya kwindawo, inkqubo yenkqubo, ithatha inkundla, isebenza kakuhle, isiqingatha iya kumasipala, enye inye ishishini elinenzuzo.

Yile ndlela i-GPU isebenza ngayo, iiprogram zingenziwa zenzelwe ukuba zingabathumeli iinkqubo ezinkulu ngendlela eqhelekileyo, kodwa kunoko zihamba ngokufana neendlela ezincinci ezicwangcisiweyo. O! mhle!

Kuze kube ngoku, azininzi iinkqubo ezenza izicelo zabo ngezi zixhobo. Uninzi, badlala ukulangazelela ukufikelela kwiibhitane ze-64 ukuxazulula iingxaki zabo zokukhawuleza, nangona sonke siyazi ukuba uDon Bill Gates uhlala ehamba ngokuhamba kwezo zixhobo zokulayisha izinto ezingadingekile kwiinguqu ezilandelayo zeWindows. Isicwangciso seWindows siquka ukukhangela i-GPU ngokusebenzisa i-API eyenzelwe ukusebenza kunye ne-DirectX 11, okuqinisekileyo ibe yindlela enye (okanye ininzi) iya kwamkela kuba iya kuyithanda njengomgangatho oqhelekileyo endaweni yokwenza izinto eziphambeneyo kwi-brand nganye ngaphandle kwe-OpenCL.

I-gflops

Igrafu ibonisa umzekelo, apho kuboniswa khona phakathi kwe-2003 kunye ne-2008 umprosesa we-nVidia nge-GPU uye wavuselela amandla akhe ngokuthelekiswa ne-Intel CPU. Kwakhona ukutshaya umahluko.

Kodwa i-GPU ikhona, sinethemba kwaye iinkqubo ze-CAD / GIS zenza ijusi efunekayo. Kuye kwavakala kakade, nangona ityala elibalaseleyo yile
I-GIS e-Manifold, kunye namakhadi e-CUDA, ukusuka kwi-nVidia, apho inkqubo yokuvelisa imodeli yendawo yedijithali ethatha imizuzu engaphezu kwemizuzu ye-6 yenziwa ngamasekhondi e-11 kuphela usebenzisa inzuzo yekhadi le-CUDA. Ukutshaya okwenzayo ukuphumelela kwiGeotech 2008.

Ekugqibeleni: Siya ku-GPU, siya kubona ngokubanzi kwiminyaka emibini ezayo.

Iimpendulo ze-5 kwi "platforms ze-CAD / ze-GIS kufuneka ziye kwi-GPU"

  1. Sawubona Vicente, ndiyabona ukuba ubonakala usebenzisa i-Windows 7.

    Ingaba kukho nto ulahlekileyo ngeXP?
    Ngaba zikho izizathu zokuba ndingayi kubuyela kwi-XP?

  2. I-7 yeWindows kwi-64bits ikuvumela ukufaka izicelo kwi-32bits ... Kwaye akukho namnye kwezicelo zam ze-GIS eziye zayeka ukusebenza.

  3. «Ngaba sele uzama i-Manifold kwi-64 bits?

    Nup ... Nangona i-PC yam ethobekileyo ine-AMD ye-bits 64, andifuni ukufaka i-Windows 64 ukususela kwi-stack ye-applications kunye nabaqhubi abayi kusebenza. Ndicinga ukuba inyathelo liza kuba ne-PC ezinikezele kwaye iya kufaka yonke into kwi-64bits ..

    Andiqinisekanga ukuba iManfold yayiya kuba yenye yezo zicelo eza kwenza umehluko wazo zilawulwe phantsi kwe-64 bits, kwaye bekungekho nje ukulungelelaniswa kodwa babeza kuthatha ijusi (njengokuba benza ngobuchwepheshe beCUDA GPU).

  4. Inqaku elihle
    Ukuba ufuna ukubona imbonakaliso yevidiyo ye-Manifold ebonisa isivinini sokuqhubisana ngokugqithiseleyo kwiibhodi zobuchwepheshe beCUDA - ezinokufakwa ngokufanayo kunye nokongeza amandla azo, nje kuphela ukuba zikhona izikholo ezikhoyo-yiya kule URL ye-YouTube : I
    http://www.youtube.com/watch?v=1h-jKbCFpnA

    Enye ibhontshisi yeembali zeMbali: I-1 Inkqubo ye-64 ye-SIG. Kwaye ngoku, i-1er SIG ekusebenziseni ubuchwepheshe beCUDA ..
