GPU ak orkestraasioŋ cluster
GPU scheduling mooy dogal ban liggéey mooy dox ci ban accelerator ak kañ, ci noonu la orchestration di koordine liggéey yooyu ci benn cluster masin.
Résumé
Together they keep expensive GPUs busy, fair, and reliable for many users and workloads.

What is GPU Scheduling and Cluster Orchestration?
GPU scheduling mooy dogal ban liggéey mooy dox ci ban accelerator ak kañ, ci noonu la orchestration di koordine liggéey yooyu ci benn cluster masin. Ñoom ñépp dañuy tëye GPU yu seer yi, gëna jub, te wóor ci jëfandikukat yu bari ak ay liggéey yu bari.
Lan moo waral waajal gañkat yi am solo ci liggéey yuñ séddale ci tàggat yaram?
Taggat buñ séddale dafay laaj rang yépp di dox benn yoon; benn-or-non gang schedule dafay tere xaaj bu xaaj biy tëju.
naka lañuy jagleel GPU yi ni ay jumtukaay ci scheduler yi?
GPU yi dañu leen di faral di jàppee ni ay yunit yuñ mëna lim, wuute nañu ak CPU yiñ mëna dagg ci anam wu ñu ko bëggee.
Lan la topologie-aware di jéema gëna baaxal?
Dafay boole rang yiy weccoo ay done ngir ñu jëfandikoo lëkkalekaay yu am bandwidth bu kawe, dagg latency jokkoo bi yépp.
Ban yokk-on lañuy gëna jëfandikoo ak Kubernetes ngir waajal ay liggéey ci IA?
Volcano (ak Kueue) yokk nañu ay mënin ngir waajal ay mbir yu bari te Kubernetes amul ci ay liggéey yu bari ci IA.
Lan mooy preemption bi ñuy jëfandikoo ci ab waajal GPU?
Preemption dafay noppalu wala di saytu liggéey yu gëna ndaw, kon liggéey yu gëna am solo mën nañu laaj GPU yi.
