Incamake
NVLink hamwe nibihuza bifitanye isano nihuta ryihuta ryemerera GPU nyinshi kuvugana muburyo butaziguye kandi vuba. Nibyingenzi kuko imyitozo no gukorera moderi nini ya AI bisaba amagana cyangwa ibihumbi bya GPU gukora nka moteri yihuta.
NVLink na GPU Ihuza ni tekinoroji yubaka tekinike igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo.
Kwibira cyane
GPU imwe ntishobora gufata moderi nini, bityo igabanijwemo chip nyinshi zigomba guhora zihana amakuru, nkibiro, gradients, hamwe nibikorwa. Bisi isanzwe ya PCIe iratinda cyane kubwibi, NVIDIA rero yashizeho NVLink, ihuza GPU-na-GPU itaziguye itanga umurongo mwinshi cyane kandi utinda cyane. Chip ya NVSwitch yagura ibi mubitambaro kugirango buri GPU muri seriveri ibashe kugera kubindi byose kumuvuduko wuzuye, ihindura GPU umunani mububiko bunini hamwe na pisine. Ku gipimo cya rack, sisitemu nka NVL72 ya NVIDIA ihuza GPU nyinshi kumurongo umwe wa NVLink. Kurenga kumurongo umwe, tekinoroji yo guhuza imiyoboro nka InfiniBand na Ethernet (akenshi hamwe na RDMA) ihuza ibihumbi nibihumbi muri cluster. Ubwiza bwibi buhuza bugabanya ingano nini nuburyo bwihuta bwerekana imyitozo.
Ubushishozi
NVLink itanga umurongo wihariye-ku-ngingo hagati ya GPUs hamwe numuyoboro mugari inshuro nyinshi za PCIe nubukererwe buke, kureka GPUs igasomana murwibutso nkaho ari hafi. NVSwitch ikora nkumuvuduko wihuse wihuta kuburyo GPUs zose muri node zitumanaho zidahagarika kumurongo wuzuye. Ibikorwa rusange nka all-kugabanya, igiteranyo cya gradients muri GPUs mugihe cyamahugurwa, ikora vuba cyane hejuru yiyi myenda, niyo mpamvu umurongo mugari uhuza imbaraga bigira uruhare runini muburyo bwo gupima umunzani kuri chip nyinshi.
Kumenya NVLink na GPU Guhuza
NVLink hamwe nibihuza bifitanye isano nihuta ryihuta ryemerera GPU nyinshi kuvugana muburyo butaziguye kandi vuba. Nibyingenzi kuko imyitozo no gukorera moderi nini ya AI bisaba amagana cyangwa ibihumbi bya GPU gukora nka moteri yihuta. NVLink na GPU Ihuza ni tekinoroji yubaka tekinike igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo. Kugirango wubake byimbitse, fata NVLink na GPU Ihuza nkicyitegererezo gikora, ntabwo ari ikintu kimwe: gusobanura ibyagezweho, gusobanura ibitekerezo, no gutandukanya ibyo sisitemu ishobora gukora byizewe nibisaba guca imanza zinzobere.
Mu myitozo, amakipe akomeye akoresha NVLink na GPU Imikoranire ihuza imyubakire, amakuru, hamwe nibikorwa remezo birwanya kwizerwa nigiciro. Bandika ibipimo ngenderwaho byerekana intsinzi, bagerageza kurwanya amakuru afatika hamwe nakazi keza, kandi bagasubiramo bashingiye kubikorwa byagaragaye ko batsinzwe aho gutsinda inshuro imwe. Aha niho imyumvire yubumenyi ihinduka mubushobozi burambye kubicuruzwa, politiki, nibikorwa.
Ibyemezo byubwubatsi bitwara imikorere nigiciro cyimikorere kumyaka. Mugihe kimwe, Guhindura igipimo kimwe gishobora guhisha intege nke za sisitemu. Uburyo bukomeye cyane ni uguhuza umuvuduko wikigereranyo hamwe na disipuline yimiyoborere: kuyobora abaderevu, gufata ibimenyetso, gutangaza ibyemezo byicyemezo, no gukomeza kuvugurura uburyo bwo kwirinda nkimyitwarire yicyitegererezo, ibyo abakoresha bategereje, nibisabwa n'amategeko bigenda bihinduka.
