Iqela le Kukhululwe abaphandi beYunivesithi yaseIllinois kutshanje ziye zaphuhliswa indlela entsha yokuhlasela ishaneli esecaleni evumela ukuba kusebenze ukuvuza kolwazi ngokudibana kwendandatho Iiprosesa zeIntel.
Malunga nolu hlobo lutsha lohlaselo Zintathu izinto ezicetywayo ezicetywayo evumela ukuba wenze oku kulandelayo:
- Ukufumana iibits nganye Ukubethela amaqhosha xa usebenzisa iRSA kunye nokuphunyezwa kwe-EdDSA okusemngciphekweni kuhlaselo lwecandelo (ukuba ukulibaziseka kokubala kuxhomekeke kwidatha eqhutywayo). Umzekelo, ukuvuza kancinci kolwazi malunga ne-vector ye-nonD ye-EdDSA kwanele ukusebenzisa uhlaselo ukubuyisa ngokulandelelana isitshixo sabucala. Olu hlaselo kunzima ukuluqhuba ngendlela kwaye lunokwenziwa ngenani elikhulu loovimba. Umzekelo, ukusebenza ngempumelelo kuboniswa ngokukhubaza i-SMT (HyperThreading) kunye nokwahlula i-LLC cache phakathi kwe-CPU cores.
- Chaza iiparameter kulibaziseko phakathi kwamaqhosha. Ulibaziseko luxhomekeke kwindawo yamaqhosha kwaye vumela, ngohlalutyo lwamanani, ukuphinda wenze idatha efakwe kwikhibhodi ngokunokwenzeka (umzekelo, uninzi lwabantu luthanda ukuthayipha "s" emva "kwe" ngokukhawuleza okukhulu kune "g" emva koko "s").
- Lungiselela ijelo lonxibelelwano ngasese ukuhambisa idatha phakathi kweenkqubo kwisantya esimalunga ne-4 megabits ngomzuzwana, engasebenzisi imemori ekwabelwana ngayo, i-cache processor, okanye izakhiwo ezithile zeprosesa kunye nezixhobo ze-CPU. Kuqatshelwe ukuba indlela ecetywayo yokudala ijelo eliyimfihlo kunzima kakhulu ukuyivimba ngeendlela ezikhoyo zokuzikhusela ekuhlaselweni ngamajelo asecaleni.
Abaphandi bakwachaza ukuba ukuxhaphaza akufuneki amalungelo aphakamileyo kwaye kunokusetyenziswa ngabasebenzisi abaqhelekileyo ngaphandle kwamalungelo, bakwakhankanya ukuba uhlaselo inokuthi yenzelwe ukulungelelanisa ukuvuza kwedatha phakathi koomatshini ababonakalayo, kodwa le ngxaki ibingaphaya kobubanzi bophando kwaye iinkqubo zokwenza ubunyani azange kuvavanywe.
Ikhowudi ecetywayo iye yavavanywa kwi-Intel i7-9700 CPU kwindawo ye-Ubuntu 16.04. Ngokubanzi, indlela yokuhlasela iye yavavanywa kwi-Intel Coffee Lake kunye neeprosesa ze-desktop ze-Skylake, kwaye inokubakho kwi-processor ye-Broadwell Xeon.
Itekhnoloji ye-Interconnect yeRingi ivele kwiiprosesa esekwe kubuchwephesha beSandy Bridge kwaye ineebhasi ezininzi ezisemva ezisetyenziselwa ukudibanisa ikhomputha kunye nemizobo yemizobo, Northbridge kunye ne-cache. Ingundoqo yendlela yokuhlaselwa kukuba ngenxa ye-bandwidth enomda webhasi yokukhwela, ukusebenza kwememori kwinkqubo enye kulibazisa ukufikelela kwimemori yenye inkqubo. Nje ukuba iinkcukacha zokumiliselwa ziphinde zenziwe ngobuchwephesha, umhlaseli unokuvelisa umthwalo okhokelela kulibaziseko lokufikelela kwimemori kwenye inkqubo kwaye usebenzise idatha yokulibaziseka njengejelo esecaleni lokufumana ulwazi.
Ukuhlaselwa kweebhasi zangaphakathi ze-CPU kuthintelwa kukusilela kolwazi malunga noyilo kunye neendlela zokusebenza zebhasi, kunye nenqanaba eliphezulu lengxolo elenza kube nzima ukukhupha idatha eluncedo. Kwakunokwenzeka ukuba uqonde imigaqo yebhasi ngokusebenzisa ubunjineli obubuyiselweyo beeprothokholi ezisetyenzisiweyo xa kugqithiswa idatha ngaphezulu kwebhasi. Ukwahlula ulwazi oluluncedo kwingxolo, imodeli yokuhlelwa kwedatha esekwe kwiindlela zokufunda ngomatshini yasetyenziswa.
Imodeli ecetywayo yenze ukuba kube nako ukulungiselela ukubekwa kweliso kulibaziseko lwekhompyuter kwinkqubo ethile, kwiimeko apho iinkqubo ezininzi ngaxeshanye zinokufikelela kwimemori kwaye inxenye yedatha ibuyisiwe kwi-cache cache.
Okokugqibela, ukuba ufuna ukwazi ngakumbi ngayo, ungajonga kwi uxwebhu olulandelayo.
