CUDA Cores ichazwe
I-CUDA, isiqulatho seComputer Architect Architecture, iteknoloji eyenziwa nguNvidia okhawuleza iinkqubo zokubalwa kweGPU.
NgeCUDA, abaphandi kunye nabaphuhlisi beefowuni bangathumela iC, C ++, kunye nekhowudi yaseFranran ngqo kwi-GPU ngaphandle kokusebenzisa ikhowudi yomhlangano. Oku kukuvumela ukuba basebenzise i-computing ehambisanayo apho amawaka emisebenzi, okanye imicu, eyenziwa ngexesha elifanayo.
Ulwazi malunga neCUDA Cores
Usenokuba ubone igama elithi CUDA xa uthengela kwikhadi levidiyo le -Nvidia. Ukuba ubheka ukupakishwa kwekhadi elinjalo okanye ufunde ukuphononongwa kwekhadi levidiyo, uya kufuthi ubone ukubhekisela kwinani leCROA.
I-CUDA cores zifana neeprosesa ezifanayo kunye nomprosesa kwikhompyutheni, enokuba ngumprosesa womibini okanye oyintloko. I-Nvidia GPUs, nangona kunjalo, inokuba namawaka angamawaka. Ezi ngqoqo zinoxanduva lwemisebenzi eyahlukeneyo evumela ukuba inani lamacandelo lidibanise ngokukhawuleza kwisantya kunye negunya le-GPU.
Ekubeni i-CUDA cores inoxanduva lokujongana nayo yonke idatha ehamba ngeGPU, ii-cores zisingatha izinto ezinjengeemifanekiso kwiimidlalo zevidiyo kwiimeko ezifana nezobumba kunye neendawo eziza kulayisha.
Izicelo zingakhiwa ukuze zisebenzise ukunyuswa komsebenzi okhutshwa yiCUDA. Ungabona uluhlu lwezicelo kwiphepha le-Nvidia's GPU Izicelo.
Iinqwelo zeCUDA zifana neenkqubo ze-AMD zokusakaza; bavele bathiwa ngokwahlukileyo. Nangona kunjalo, awukwazi ukulinganisa i-300 CUDA Nvidia GPU kunye ne-300 Stream Processor AMD GPU.
Ukukhetha iKhadi leVidiyo kunye neCUDA
Inombolo ephezulu yamacandelo eCUDA ngokuqhelekileyo kuthetha ukuba ikhadi levidiyo libonelela ngokukhawuleza ukusebenza ngokubanzi. Nangona kunjalo, inani leCUDA cores linye yezinto ezininzi ezinokuqwalaselwa xa ukhetha ikhadi levidiyo .
I-Nvidia inikeza uluhlu lweemakhadi ezibonakalisa zimbalwa njengee-8 ze-CUDA, ezifana ne-GeForce G100, ukuya kwii-5,760 zeCUDA kwii-GeForce GTX TITAN Z.
Amakhadi ezobuGcisa ayenayo iTesla, Fermi, Kepler, Maxwell, okanye iPaccal ukwakha iCUDA.
