CUDA Makore Akatsanangurwa
CUDA, chirevo cheCompute Unified Device Architecture, inyanzvi yakagadzirwa naNvidia iyo inowedzera nzira dzekuverenga GPU.
NeCUDA, vatsvakurudzi nevashambadziri vepurogiramu vanogona kutumira C, C ++, uye Code Fortran zvakananga kuGPU pasina kushandisa kereke yegungano. Izvi zvinoita kuti vashandise kushandisa iyo yakafanana computing umo zviuru zvemabasa, kana tsvina, zvinourawa panguva imwe chete.
Mashoko pamusoro peCUDA Cores
Iwe unogona kunge wakaona izwi rokuti CUDA apo unotenga kadhi yevhidhiyo yeNvidia. Kana iwe ukatarisa kuiswa kwekadhi rakadaro kana kuverenga kuongorora kadhi yemavhidhiyo, iwe unowanzoona kuongororwa kwenhamba yeCUDA cores.
CUDA cores inofanana nevanoronga purogiramu yakafanana nepurogiramu mumakombiyuta, iyo inogona kunge iri vaviri kana kuti quad-core processor. Nvidia GPUs, zvisinei, inogona kuva nezviuru zvamazana emabhiza. Izvi zvinokonzera mabasa akasiyana-siyana anobvumira kuti nhamba yeoraire inoratidze zvakananga nekukurumidza nesimba reGPU.
Sezvo CUDA yakagadziriswa inotarisirwa kuita nezvose zvinotungamira kuburikidza neGPU, maitiro anobata zvinhu zvakadai semifananidzo mumitambo yemavhidhiyo kumamiriro ezvinhu akadai apo vanhu vemavara nemamiriro ekunze vari kutakura.
Zvikumbiro zvinogona kuvakwa kuti zvibatsirwe nekuwedzera kwekuita kunoitwa neCUDA cores. Iwe unogona kuona runyora rwezvidzidzo izvi pane peji yeNdidia's GPU Applications.
CUDA mapepa akafanana neA AMD's Stream processors; ivo vachangotumidzwa zvakasiyana. Zvisinei, haugoni kuenzanisa 300 CUDA Nvidia GPU ine 300 Stream Processor AMD GPU.
Kusarudza Kadhi yeVhidhiyo neCUDA
Nhamba yakakwirira yeCUDA cores inoreva kuti kadhi yevhidhiyo inopa hurumende kushanda zvakakwana. Zvisinei, nhamba yeCUDA cores inongova chimwe chezvinhu zvakasiyana siyana zvinofanira kutariswa pakusarudza kadhi yevhidhiyo .
Nvidia inopa huwandu hwemakadhi anoratidza se mashoma se 8 CUDA cores, semuGeForce G100, kusvika kune 5760 CUDA yekare muGeForce GTX TITAN Z.
Mifananidzo yemakadhi ane Tesla, Fermi, Kepler, Maxwell, kana Pascal architecture inotsigira CUDA.
