Mount Mayhem ku Netflix: Kukulitsa Zotengera pa Ma CPU Amakono

Kuweta Phiri: Netflix's Toolbox for CPU Efficiency

Kuti mugonjetse "Mount Mayhem" iyi, mainjiniya a Netflix apanga njira zapamwamba zomwe zimapitilira kukonza zotengera. Njira yawo ndi yaukadaulo pakuwongolera zida za granular, matekinoloje owonjezera omwe amapangidwa mu Linux kernel ndi zigawo zawo zoyimba. Chofunikira pamalingaliro awo ndikumvetsetsa kuti CPU pachimake sichinthu chosavuta kukonza. Amayang'ana kwambiri mbali zingapo zofunika:

• CPU Pinning: Kupereka zotengera zinazake ku CPU cores kuti muchepetse kusinthana kwamutu ndikusintha malo osungira.
• Load Balancing: Kugawa mwanzeru zonyamulira zonyamulira pakati pa ma cores kuti mupewe vuto lililonse kuti lisasokonezeke.
• Kuthana ndi Zosokoneza: Kuwongolera kusokoneza kwa hardware kuonetsetsa kuti sikusokoneza ma cores ofunikira kwambiri omwe akuyendetsa ntchito zomwe zimayang'ana ogwiritsa ntchito.
• Chidziwitso pa Cache: Kukonza zotengera zodziwitsa za kachesi ya CPU, kupanga magulu okhudzana ndi ntchito kuti muchulukitse kugunda kwa cache.

Ntchito yakuzama iyi ndi yomwe imalola Netflix kutsitsa makanema apamwamba kwambiri kwa olembetsa opitilira 200 miliyoni nthawi imodzi, kupangitsa zovuta zomwe zingachitike kukhala chitsanzo chakuchita bwino.

Amafunikira nsanja yomwe imachotsa zovuta zotsika za CPU ndandanda ndi kasamalidwe ka zinthu, kulola magulu kuti aziganizira kwambiri zomanga ndi kutumiza mapulogalamu awo.

"Kusinthika kwa cloud computing kusuntha vuto la makulitsidwe kuchoka pakupereka makina enieni kupita kukukonzekera mwanzeru zolemetsa za kernel. Ndiko kuvina kovutirapo pakati pa logic yogwiritsira ntchito ndi hardware."
