Ukuhlela kwe-GPU ne-Cluster Orchestration
Ukuhlela i-GPU kunquma ukuthi yimiphi imisebenzi esebenza kuma-accelerator futhi nini, kuyilapho i-orchestration ixhumanisa le misebenzi kuyo yonke iqoqo lemishini.
Uhlolojikelele
Together they keep expensive GPUs busy, fair, and reliable for many users and workloads.
I-Deep Dive
Kuqoqo le-AI okwabelwana ngalo, inqwaba yabasebenzisi baqhudelana ngama-GPU ayindlala angabiza amashumi ezinkulungwane zamadola lilinye. Umhleli ufana nezidingo zomsebenzi ngamunye (inombolo yama-GPU, inkumbulo, i-topology) kuzingxenyekazi zekhompuyutha ezitholakalayo, uphoqelela izinto ezibalulekile kanye nezabelo zokwabelana ngokufanelekile, futhi ulayini uyasebenza lapho iqoqo ligcwele. I-orchestration iqhubekela phambili: ibeka iziqukathi, ikhweze idatha, ibambe ukwehluleka, iqale kabusha izisebenzi eziphahlazekile, futhi ithunge ndawonye ukuqeqeshwa okusatshalaliswa kwamanodi amaningi. I-Kubernetes ene-plugin yedivayisi ye-NVIDIA nezengezo ezifana ne-Volcano noma i-Kueue iphatha ukuhlela kwamaqembu ezigelekeqe, lapho bonke abasebenzi bomsebenzi osabalalisiwe kufanele baqale ndawonye noma bangakwenzi lutho. Ukuhlela okuhle futhi kuhlonipha i-GPU interconnect topology, amarenki okuhlanganisa ndawonye adinga ukuxhumana okusheshayo kwe-NVLink ukuze kugwenywe izithiyo ezihamba kancane ze-cross-node.
I-Technical Insight
Ama-GPU adalulwa njengezisetshenziswa ezibalekayo, ezingahlukaniseki, ngakho abahleli bawalandelela njengamanani aphelele kunemijikelezo ye-CPU eyabiwayo. Ukuhlela kweqembu (noma ngokubambisana) kubalulekile: umsebenzi wokuqeqesha osabalalisiwe onamazinga angu-64 okuvala uma kuphela ama-GPU angu-60 anikezwe, ngakho umhleli kufanele abele konke noma lutho. Ukubekwa kwe-Topology-aware kufunda izakhiwo ze-NVLink ne-InfiniBand ukuze kugcinwe amazinga okuxhumana eduze, kuncishiswe ukubambezeleka kokunciphisa konke okubusa ukuqeqeshwa kwamamodeli amakhulu.
I-Strategic Impact

Izinqumo zezakhiwo ziqhuba ukusebenza kanye nezindleko zokusebenza iminyaka.
Izinqumo ezicacile
Imfundo yobuchwepheshe isiza amaqembu ukuthi akhethe isitaki esifanele, hhayi nje esisha.
Ukulawulwa kwekhwalithi
Izinketho ezingcono zobunjiniyela zinciphisa izehlakalo ezinokwethenjelwa ekukhiqizeni.
Ikusasa Lokuhlela i-GPU ne-Cluster Orchestration
Abashejuli baya ngokuya behlakanipha mayelana nama-GPU ama-fractional kanye nesikhathi abelwene ngaso, ukupakishwa kwemigqomo okuqaphela i-MIG, kanye nokulungiselela okuhlola imisebenzi ukuze kubuyiselwe umthamo womsebenzi obaluleke kakhulu. Lindela ukuhlanganiswa okujulile namandla nokuthuthukisa izindleko, ukusetshenziswa kabusha komthamo, kanye nokuhlela okuzenzakalelayo kwamaqembu ezigelekeqe ukuze uthole ukuqeqeshwa okunwebekayo okukhulayo noma okunciphisa ukubalwa kwezisebenzi. Njengoba amaqoqo afinyelela emashumini ezinkulungwane zama-GPU, i-orchestration ebekezelela amaphutha esinda ekwahlulekeni kwehadiwe okuvamile iba ibalulekile.
Ukuqaliswa Komhlaba Wangempela
Ilebhu yocwaningo isebenzisa ama-quota esabelo esifanelekile ukuze kungabikho iqembu elilodwa elingakwazi ukudonsa wonke ama-GPU kuyilapho abanye belindile kulayini.
U-Kubernetes neqembu le-Volcano-uhlela umsebenzi wokuqeqesha we-32-GPU ukuze wonke umsebenzi aqale ngesikhathi esisodwa, avimbele ukuvala ingxenye ethile yesabelo.
Umhleli ulungiselela ukuhlolwa okungabalulekile kakhulu, akuhlole, futhi akhulule ama-GPU ukuze aqalise ukuqeqeshwa kabusha kokukhiqiza okuphuthumayo.
Ukubekwa kwe-Topology-aware kuhlanganisa amarenki ayisishiyagalombili endaweni eyodwa exhunywe ku-NVLink ukuze kusheshiswe ukuncishiswa kwe-gradient.

Imibuzo evame ukubuzwa
What is GPU Scheduling and Cluster Orchestration?
Ukuhlela i-GPU kunquma ukuthi yimiphi imisebenzi esebenza kuma-accelerator futhi nini, kuyilapho i-orchestration ixhumanisa le misebenzi kuyo yonke iqoqo lemishini. Ndawonye bagcina ama-GPU abizayo ematasa, alungile, futhi anokwethenjelwa kubasebenzisi abaningi nemithwalo yomsebenzi.
Kungani ukuhlela kwezigelekeqe kubalulekile emisebenzini yokuqeqeshwa esabalalisiwe?
Ukuqeqeshwa okusatshalaliswayo kudinga wonke amarenki asebenze kanyekanye; ishejuli yeqembu lezigelekeqe elisho konke noma lutho livimbela ukwaba ingxenye elengayo.
Ama-GPU ngokuvamile amodelwa kanjani njengesisetshenziswa ngabahleli?
Ama-GPU ngokuvamile aphathwa njengamayunithi aphelele angabalwa, ngokungafani namasheya e-CPU angasikwa ngokungekho emthethweni.
Yini ukuhlela okuqaphela i-topology ezama ukuyithuthukisa?
Ithola ngokuhlanganyela amarenki ashintshanisa idatha ukuze asebenzise izixhumanisi zomkhawulokudonsa ophezulu, ukusika konke ukunciphisa ukubambezeleka kokuxhumana.
Isiphi isengezo esivame ukusetshenziswa ne-Kubernetes ekuhleleni inqwaba nemisebenzi ye-AI?
I-Volcano (kanye ne-Kueue) yengeza inqwaba namakhono okuhlela amaqembu ezigelekeqe i-vanilla Kubernetes angenawo ngomthwalo we-AI.
Kusetshenziselwani ukukhululwa kusihleli se-GPU?
Ukuzilungiselela kuyaphumula noma izindawo zokuhlola imisebenzi ebaluleke kancane ukuze umsebenzi ophuthumayo, obaluleke kakhulu ukwazi ukufuna ama-GPU.
