Amapulatifomu we-CAD / GIS kufanele ahambe ku-GPU

Labo bethu abasebenzisa izinhlelo zokusebenza zokuqhafaza bahlala belindele ukuthi amakhompyutha abe nememori yokusebenza eyanele. Kulokhu, izinhlelo ze-CAD / GIS bezilokhu zibuzwa noma zilinganiswa ngokuya ngesikhathi esithathayo ukwenza imisebenzi yansuku zonke efana nale:

• Ukuhlaziywa kwendawo
• Ukulungiswa nokubhaliswa kwezithombe
• Ukuthunyelwa kwedatha enkulu
• Ukuphathwa kwedatha ngaphakathi kwe-geodatabase
• Isevisi yedatha

I-PC yendabuko ayikashintshi kakhulu eminyakeni yamuva, ngokwe-RAM, i-hard disk, imemori yemifanekiso nezici eziye zanda; kodwa lo logic operation of the CPU uye wagcina design yayo yasekuqaleni (Yingakho siqhubeka simbiza nge-CPU). Kubuye kwaba yinto embi ukuthi njengoba amaqembu ekhula emandleni, izinhlelo zibulala ukulindela kwazo ngokuziqambela ukuthi zisebenzise amandla amasha.

Isibonelo, (futhi isibonelo kuphela) Lapho abasebenzisi ezimbili ezibekwe ngesikhathi esifanayo ngaphansi kwezimo ezifanayo imishini kanye idatha, omunye AutoCAD 2010 nesinye Microstation V8i, kulayishwa 14 raster izithombe, ifayela parcelario 8,000 izakhiwo kanye uxhumano database ngekwendzawo Oracle, sizibuza umbuzo:

Iyini enye yezinto ezimbili, ukuze ungawehli umshini?

Impendulo ayikho emisha, kuyindlela nje uhlelo olwenziwa ngayo, ngoba lokhu akunjalo nge-AutoDesk Maya, eyenza izinto ezinobuhlakani futhi esebenza kangcono. Indlela yokuxhaphaza i-PC iyefana (kuze kube manje ezimweni zezinhlelo ezimbili), futhi ngokususelwa kulokhu sidubula izinhlelo, ngoba sizisebenzisa ukusebenza, nokuningi. Ngakho-ke, amanye amakhompyutha aziwa njengama-PC wendabuko, izindawo zokusebenza noma amaseva; hhayi ngoba zineminye imibala, kodwa ngenxa yendlela ezenza ngayo izinhlelo ezisebenzisa kakhulu ekusetshenzisweni kwemidwebo, ukucutshungulwa kwamavidiyo, ukuthuthukiswa kohlelo lokusebenza, imisebenzi yeseva, futhi kithi, ukusebenza kwedatha yendawo.

I-CPU encane, i-GPU engaphezulu

Evelele kakhulu izinguquko zesimanje ziye zenzeka ukuze nesimo sesakhiwo esikhulu PC leli gama livele GPU (Process Unit Graphics), ukuthola ukusebenza computer kangcono, okwenza onkhe mkhulu umsebenzi omncane kanyekanye, ngokudlula abaphathi we-CPU (Central Process Unit), amandla akhe okusebenza adlala phakathi kokuvuselelwa kwe-hard disk, imemori ye-RAM, imemori yevidiyo kanye neminye imininingwane (hhayi abanye abaningi).

Amakhadi wemidwebo awenziwa ukwandisa imemori yevidiyo, kepha afake iprosesa equkethe amakhulu ama-cores enzelwe ukuqhuba izinqubo ezifanayo. Lokhu bebelokhu benakho (okungenani noma ngaphansi), Kepha inzuzo yamanje ukuthi laba bakhiqizi banikela ngokwakhiwa okuthile okuvulekile (cishe) ukuze onjiniyela be-software bakwazi ukucabangela ubukhona bekhadi lalezi zakhono futhi basebenzise amandla alo. I-PC Magazine kulo Januwari ibalula izinkampani ezifana neNVidia, ATI nezinye ezifakwe kulo mfelandawonye VulaCL

Ukuqonda umehluko phakathi kwe-CPU ne-GPU, bheka ngibhekisela emfanekisweni:

I-CPU, yonke indawoKufana nomasipala onakho konke okumaphakathi, okunecebo lokuhlela amadolobha, uyazi ukuthi kufanele ulawule ukukhula kwawo kepha akakwazi ukuphatha ngisho nokwakhiwa okusha okwephula inkambiso. Kepha esikhundleni sokunikeza lo msebenzi ezinkampanini ezizimele, uyaphikelela ekutheni athathe le ndima, abantu abazi ukuthi bazokhalaza kubani ngomakhelwane ohamba eceleni komgwaqo, futhi idolobha liyaqhubeka nokukhubazeka kakhulu nsuku zonke. 

Uxolo, awukhulumi ngameya wakho, usho nje ngomfanekiso we-CPU, lapho le Central Process Unit (uma kwenzeka iWindows) kufanele yenza ithimba lenze izinqubo ezifana nalezi:

• Izinhlelo ezisebenza lapho iWindows iqala, njenge-Skype, Yahoo Messenger, Antivirus, Java Engine, njll. Konke okudla ingxenye yememori yokusebenza ngokubaluleka okuphansi kepha ngokungadingekile ngaphandle kokuthi kuguqulwe yi-msconfig (abanye abayinaki).
• Izinsizakalo ezisebenzayo, eziyingxenye ye-Windows, izinhlelo ezisetshenziswa ngokujwayelekile, i-hardware exhunyiwe noma ezinye ezikhishiwe kepha zihlala lapho zisebenza. Lokhu kuvame ukuba nokubekwa okuphakathi / okuphezulu.
• Izinhlelo ezisetshenziswayo, ezidla isikhala esinokubaluleka okuphezulu. Sizwa ukushesha kwabo ukwenziwa esibindi ngoba siqalekisa uma bengakwenzi ngokushesha yize benethimba elenza kahle. 

Nanobe iWindows isebenza kahle, imikhuba enjengezinhlelo eziningi ezivulekile, ukufaka noma ukukhipha ngokungenasici, izihloko ezingadingekile ezibonakalayo i-pintones, basenza sinecala lokungasebenzi kahle kwemishini.

Kwenzeke-ke, ukuthi uma siqala inqubo yalabo okukhulunywe ngabo ekuqaleni, iprosesa izokwenza ukuphazamisa ukakhukhunathi ngifuna ukubeka phambili lokhu ngaphezu kwezinye izinhlelo ezisetshenziswayo. Izinketho zakho ezimbalwa ongazisebenzisa kahle yimemori ye-RAM, imemori yevidiyo (evame ukwabelwana ngayo), uma kukhona ikhadi lemidwebo, thola okuthile kulo, kuya ngohlobo lwe-hard drive nezinye izinto eziyize, ukukhala okudabukisayo kungaba kuncane.

I-GPU, izinqubo ezifanayo, Kufana nomasipala othatha isinqumo sokubeka phansi amandla, ukuvumela noma ukwenze kube ngezakho lezo zinto ezingafinyeleleki, okuthi, nakuba kuyizinqubo ezinkulu, zilethwe ngemisebenzi emincane. Ngakho-ke, ngokususelwa kumithethonqubo yamanje, inkampani ezimele inikezwa indima yokuqapha ukwephulwa kwezijeziso ngendlela ethile. Ngenxa yalokho (isibonelo nje), isakhamuzi singagcwalisa leyo njabulo okumnandi yokutshela izimbambo kumakhelwane osusa inja shit eceleni kwendlela yakhe, owakha udonga ngokuthatha ingxenye yomgwaqo, opaka imoto yakhe ngokungafanele, njll. Inkampani iyaphendula ucingo, iya endaweni, icubungule isenzo, iyise enkantolo, ikhiphe inhlawulo, isigamu siye kumasipala, elinye ibhizinisi elinenzuzo.

Yile ndlela i-GPU esebenza ngayo, izinhlelo zingahle zenzelwe ukuze zingathumeli izinqubo ezinkulu ngendlela evamile, kodwa kunalokho zihamba ngokufana nezinhlelo ezincane ezihlungiwe.  O! amazing!

Kuze kube manje, aziziningi izinhlelo ezenza izinhlelo zazo zokusebenza ngalezi zici. Iningi labo, bafisa ukufinyelela kuma-bits angama-64 ukuxazulula izinkinga zabo zokuhamba kancane, yize sonke sazi ukuthi uDon Bill Gates uzohlala ehamba kulawo makhono ngokulayisha izinto ezingadingekile kuzinguqulo ezilandelayo zeWindows. Isu leWindows lifaka ukusebenzisa i-GPU ngokusebenzisa ama-API aklanyelwe ukusebenza ku-DirectX 11, okuzoba ngenye indlela ezokwamukelwa yiwo wonke umuntu (noma iningi) ngoba bazoyikhetha njengezinga elijwayelekile esikhundleni sokwenza izinto ezihlanyayo zomkhiqizo ngamunye ngaphandle kwe-OpenCL.

Igrafu ikhombisa isibonelo, esibonisa ukuthi phakathi kuka-2003 no-2008 iprosesa ye-nVidia nge-GPU ibilokhu iguqula amandla ayo uma iqhathaniswa ne-Intel CPU. Futhi i- incazelo yokubhema umahluko.

Kepha amandla we-GPU akhona, ngethemba nokuthi izinhlelo ze-CAD / GIS zithola ijusi edingekayo. Sekuvele sekulalelwe, yize icala elivelele kakhulu ele-d
e I-GIS eninginingi, enamakhadi we-CUDA, avela ku-nVidia, lapho inqubo yokwenziwa kwemodeli yendawo yedijithali ethathe ngaphezu kwemizuzu eyi-6 yenziwa ngemizuzwana eyi-11 nje, kusizakala ngokuba khona kwekhadi le-CUDA. Babhema okwenze bona thola i-Geotech 2008.

Ekuphethweni:  Siya ku-GPU, ngokuqinisekile sizobona okuningi eminyakeni emibili ezayo.
