MunaFebruary, Stanford yakaita musangano wepamusoro-performance computing (HPC). Vamiriri veVMware vakati kana vachishanda neGPU, sisitimu yakavakirwa pane yakagadziridzwa ESXi hypervisor haina kuderera mukumhanya kune isina simbi mhinduro.
Isu tinotaura nezve matekinoroji akaita kuti zvikwanise kuita izvi.

Performance issue
Maererano nevanoongorora, inenge 70% yemabasa akawanda munzvimbo dze data . Nekudaro, iyo 30% yasara ichiri kumhanya pane isina simbi isina hypervisors. Iyi 30% inonyanya kuve neyakakura-mutoro maapplication, akadai seaya ane chekuita nekudzidziswa neural network, uye kushandisa maGPU.
Nyanzvi dzinotsanangura maitiro aya nenyaya yekuti iyo hypervisor, seyepakati abstraction layer, inogona kukanganisa mashandiro ehurongwa hwese. Muzvidzidzo makore mashanu apfuura nezvekuderedza kukurumidza kwebasa ne10%. Naizvozvo, makambani uye data center operators havasi kukurumidza kuendesa HPC mitoro yebasa kunzvimbo chaiyo.
Asi virtualization tekinoroji dziri kuvandudza nekuvandudza. Pamusangano mwedzi wapfuura, VMware yakati iyo ESXi hypervisor haina kukanganisa kuita kweGPU. Kumhanya kwekombuta kunogona kudzikiswa nezvikamu zvitatu kubva muzana, izvo zvinofananidzwa nesimbi isina chinhu.
Sei basa iri
Kuvandudza mashandiro eHPC masisitimu ane maGPU, VMware yakaita shanduko dzinoverengeka kune hypervisor. Kunyanya, yakabviswa vMotion basa. Inodiwa pakuyera kuyera uye kazhinji inotamisa machina chaiwo (VMs) pakati pemaseva kana maGPU. Kudzima vMotion kwakakonzera kuti VM yega yega igoverwe chaiyo GPU. Izvi zvakabatsira kuderedza mari pakuchinjana data.
Chimwe chikamu chakakosha chehurongwa DirectPath I/O. Iyo inobvumira iyo CUDA parallel computing mutyairi kupindirana nemashini chaiwo zvakananga, ichipfuura iyo hypervisor. Paunenge uchida kumhanya akati wandei maVM pane imwe GPU kamwechete, iyo GRID vGPU mhinduro inoshandiswa. Iyo inokamura ndangariro yekadhi muzvikamu zvakati wandei (asi iyo computational kutenderera haina kukamurwa).
Iyo dhizaini yekushanda yemashini maviri chaiwo mune iyi kesi ichaita seizvi:
Mibairo uye zvakafanotaurwa
The company hypervisor nekudzidzisa mutauro modhi yakavakirwa pa . Kuita "kukuvadza" kwaingova 3-4% kana ichienzaniswa nesimbi isina chinhu. Mukudzoka, iyo system yakakwanisa kugovera zviwanikwa pane zvaidiwa zvichienderana nemutoro wazvino.
Iyo IT hofori zvakare nemidziyo. Mainjiniya ekambani akadzidzisa neural network kuona mifananidzo. Panguva imwecheteyo, zviwanikwa zveGPU imwe zvakagoverwa pakati pemidziyo ina VM. Nekuda kweizvozvo, kuita kwemashini ega ega kwakadzikira ne17% (ichienzaniswa neVM imwechete ine mukana wakazara weGPU zviwanikwa). Zvisinei, nhamba yemifananidzo inogadziriswa pasekondi katatu. Zvinotarisirwa kuti maitiro akadaro maapplication mukuongorora data uye kuenzanisira komputa.
Pakati pematambudziko anogona kusangana neVMware, nyanzvi pane vateereri vadiki vakananga. Nhamba shoma yemakambani ichiri kushanda nepamusoro-soro masisitimu. Kunyangwe muStatista kuti panosvika 2021, 94% yepasi rose data center workloads ichange yave virtualized. By Vaongorori, kukosha kwemusika weHPC kuchakura kubva pamakumi matatu nemaviri kusvika kumakumi mana nemashanu emadhora panguva kubva 32 kusvika 45.
