Together they keep expensive GPUs busy, fair, and reliable for many users and workloads.
Kudzika Kwakadzika
Mune yakagovaniswa AI cluster, akawanda evashandisi anokwikwidza kushomeka maGPU anogona kuita makumi ezviuru zvemadhora imwe neimwe. Anoronga anowirirana nezvinodiwa zvebasa rega rega (nhamba yeGPUs, ndangariro, topology) kune iripo Hardware, inosimbisa zvinokosheswa uye zvakaringana-gova quotas, uye mitsetse inoshanda kana sumbu razara. Orchestration inoenderera mberi: inoisa midziyo, inokwirisa data, inobata kutadza, inotangisazve vashandi vakaputsika, uye inosona pamwechete akawanda-node akagoverwa kudzidziswa. Kubernetes ine NVIDIA mudziyo plugin uye ma-add-ons seVolcano kana Kueue anobata kuronga kwechikwata, uko vashandi vese vebasa rakagoverwa vanofanirwa kutanga pamwe chete kana kusaita. Kuronga kwakanaka kunoremekedzawo GPU interconnect topology, kubatanidza nzvimbo dzekutsvaga dzinoda kukurumidza NVLink kutaurirana kudzivirira kunonoka kuyambuka-node mabhodhoro.
Kuitwa muNyika yeChokwadi
Lab yekutsvagisa inoshandisa fair-share quotas saka hapana timu imwe chete inogona kutakura maGPU ese vamwe vakamirira mumutsara.
Kubernetes nechikwata cheVolcano-anoronga 32-GPU basa rekudzidzisa kuitira kuti mushandi wese atange kamwechete, kudzivirira chikamu-chekugoverwa-chikafa.
Anoronga anofanotungamira kuyedza kwakaderera, kutarisisa, uye kusunungura maGPU kuitira kukurumidza kugadzirwa kwekudzidzira kumhanya.
Topology-inoziva kuiswa pamwe-inowana masere masere pane imwe NVLink-yakabatana node kuti ikurumidze gradient kudzikisa zvese.
Ramangwana reGPU Kuronga uye Cluster Orchestration
Vagadziri vari kuwedzera hungwaru nezve maGPU akapatsanurwa uye akagovaniswa nguva, MIG-inoziva bin-packing, uye preemption iyo inotarisisa mabasa kudzoreredza simba repamusoro-basa rekutanga. Tarisira kubatanidzwa kwakadzama nesimba uye kuvandudza mutengo, kushandisazve kugona, uye otomatiki kuronga kwechikwata chekudzidzira elastic inokura kana kuderedza nhamba yevashandi. Sezvo masumbu anokwira kusvika kumakumi ezviuru zveGPU, kutadza-kushivirira orchestration inopona kazhinji kukundikana kwehardware inova yakakosha.
Kuzvishandisa

- Mutengo uye bhajeti. Zvisarudzo zvezvivakwa zvinotyaira kuita uye mutengo wekushandisa kwemakore.
- Sarudzo dzakajeka. Dzidzo yehunyanzvi inobatsira zvikwata kusarudza murwi wakakodzera, kwete iwo mutsva chete.
- Kudzora kwemhando yepamusoro. Sarudzo dzeinjiniya dziri nani dzinoderedza zviitiko zvekuvimbika mukugadzira.

- Kugadzirisa imwe bhenji kunogona kuvanza yakafara system kushaya simba.
- Infrastructure uye mari yekugadzirisa inowanzotarisirwa pasi.
- Chengetedzo uye kucherechedzwa mapundu anogona kukura sezvo masisitimu anowedzera kuoma.

What is GPU Scheduling and Cluster Orchestration?
Kuronga kweGPU kunosarudza kuti ndeapi mabasa anomhanya pane accelerator uye rinhi, nepo orchestration inoronga mabasa aya muboka rose remichina. Pamwe chete vanochengeta maGPU anodhura akabatikana, akanaka, uye akavimbika kune vakawanda vashandisi uye mitoro yebasa.
Why coordinate resource admission for a fixed-size distributed training worker group?
Gang-style admission helps obtain the needed worker group. It does not prove all partial allocations deadlock or provide exact simultaneous process starts.
How does Kubernetes normally express a device-plugin GPU resource request?
Device plugins advertise countable resources. Configured MIG or sharing mechanisms affect which resources are exposed.
Chii chinonzi topology-inoziva kuronga inoedza kukwirisa?
Iyo inobatana-inotsvaga masanji ekuchinjana data saka ivo vanoshandisa yakakwira-bandwidth zvinongedzo, kucheka zvese-kuderedza kutaurirana latency.
Ndeipi yekuwedzera-inowanzo shandiswa neKubernetes kune batch uye kuronga kwezvikwata zveAI mabasa?
Volcano (uye Kueue) wedzera batch uye gang-kuronga kugona izvo vanilla Kubernetes inoshaikwa kune AI mabasa.
What must a training application provide if a preempted job should resume its previous progress?
Preemption reclaims resources; it does not inherently save training progress. Checkpointing and restart logic are needed for continuation.
