Apple: Ukulungisa ukuba semngciphekweni kweZombieLoad kunokunciphisa ukusebenza kweMac ngama-40%

U-Apple uthe ukujongana ngokupheleleyo nokuba sesichengeni kweZombieLoad kwi-Intel processors kunokunciphisa ukusebenza ukuya kuthi ga kwi-40% kwezinye iimeko. Ngokuqinisekileyo, yonke into iya kuxhomekeka kwiprosesa ethile kunye nemeko apho isetyenziswe khona, kodwa kuyo nayiphi na imeko oku kuya kuba yinto ephawulekayo ekusebenzeni kwenkqubo.

Ukuqala, masikukhumbuze ukuba ngenye imini yaziwa malunga nobunye ubuthathaka obufunyenwe kwiiprosesa ezininzi ze-Intel. Ibizwa ngokuba yiZombieLoad, nangona i-Intel ngokwayo ikhetha ukusebenzisa igama elingathathi hlangothi leMicroarchitectural Data Sampling (MDS) okanye iSampuli yeDatha yeMicroarchitectural. Sele sithethile ngeenkcukacha ezithile malunga ingxaki ngokwayo kwaye iyafumaneka iindlela zokuyicombulula.

Ngoku i-Apple ipapashe ingxelo yayo malunga ne-MDS, kuba zonke iikhompyuter zayo zeMac zakhiwe kwi-Intel chips, kwaye ke zinokuhlaselwa. Inkampani ikwabonelela ngendlela enzima, kodwa esebenzayo, ngokutsho kwayo, indlela yokukhusela ikhompyuter yakho.

"I-Intel ifumene ubuthathaka obubizwa ngokuba yi-microarchitectural data sampling (MDS) echaphazela i-desktop kunye neekhompyuter zelaptop ezine-Intel processors, kubandakanya zonke iiMacs zanamhlanje.

Ngeli xesha lokubhala, akukho zenzo zaziwayo ezichaphazela abathengi bethu. Nangona kunjalo, abasebenzisi abakholelwa ukuba ikhomputha yabo isengozini enkulu yokuhlaselwa banokusebenzisa isicelo seSiteminali ukwenza umyalelo owongezelelweyo we-CPU kunye nokukhubaza iteknoloji ye-Hyper-Threading ngokwabo, eya kubonelela ngokhuseleko olupheleleyo kule miba yokhuseleko.

Olu khetho luyafumaneka kwiMacOS Mojave, iSierra ephezulu kunye neSierra. Kodwa inokuba nempembelelo enkulu ekusebenzeni kwekhompyuter yakho.

Uvavanyo olwenziwe yi-Apple ngoMeyi ka-2019 lubonise ukwehla kokusebenza ukuya kuthi ga kwi-40%. Uvavanyo luquke imithwalo yomsebenzi enemisonto emininzi kunye nebenchmarks ezifumaneka esidlangalaleni. Iimvavanyo zentsebenzo zenziwa kusetyenziswa iikhompyuter ezikhethiweyo zeMac. Iziphumo ezizizo zinokwahluka ngokuxhomekeke kwimodeli, ulungelelwaniso, ukusetyenziswa kwemeko kunye nezinye izinto."

Qaphela ukuba inkampani Intel yatsho ukuba ukukhubaza i-Hyper-Threading akuyomfuneko. Kufuneka nje usebenzise isoftware eqinisekisiweyo. Ngokwenyani, i-Apple iphinde yashiya umsebenzisi ukhetho: zikhusele ngokupheleleyo kwaye zinciphise ukusebenza, okanye zishiye yonke into njengoko injalo. I-Intel ikwaqaphele ukuba sele isebenzise iipetshi zehardware ngokuchasene ne-MDS kwiprosesa yayo yesibhozo neyesithoba, kunye nakwisizukulwana sesibini iXeon-SP processors (iCascade Lake), ke abasebenzisi bezi chips abanaxhala malunga nokuba sesichengeni okutsha. .

Kodwa ngokubanzi, kuyavela ukuba ukuqinisekisa ukhuseleko olupheleleyo kwiZombieLoad, kufuneka uhlaziye ulungelelwaniso lwenkqubo kwaye usebenzise iprosesa yamva nje kuyo, okanye ukhubaze i-Hyper-Threading, ngaloo ndlela unciphisa kakhulu ukusebenza kwenkqubo. Nangona le yokugqibela ayiyi kukhusela kwezinye izoyikiso ezisebenzisa umyalelo oqikelelwayo wokubulawa. Kukho, nangona kunjalo, enye inketho - ukusebenzisa inkqubo kwiprosesa ye-AMD. Kodwa kwimeko yeekhompyuter ze-Apple oku akunakwenzeka.
