Imibuzo Ebuzwa Rhoqo

Yintoni ukuhlelwa okungenasebe kwaye kutheni kubalulekile?

Ukuhlela okungenasebe kuphelisa amasebe anemiqathango (ukuba/enye iingxelo) ukusuka kwimisebenzi yothelekiso, kuvumela umbhobho weCPU ukuba uphumeze ngaphandle kwezohlwayo zokucingela kakubi. Iiprosesa zanamhlanje zixhomekeke kuqikelelo lwesebe, kwaye xa uqikelelo lusilela, umbhobho uyayeka. Uyilo olungenasebe lusebenzisa ubuchule be-arithmetic njengeentshukumo ezinemiqathango zokugcina idatha ihamba kakuhle, okukhokelela kumaxesha akhawulezayo okulungisa kwiiseti zedatha ezinkulu okanye ezingalindelekanga.

Kukhawuleza kangakanani ukuhlela okungenasebe xa kuthelekiswa neendlela zakwantu?

Iinzuzo zokusebenza zixhomekeke kwiimpawu zedatha, kodwa ukuhlelwa ngaphandle kwesebe kunokuba yi-2–5x ngokukhawuleza kwigalelo elingalindelekanga okanye elichaseneyo apho uqikelelo lwesebe lusilela rhoqo. Kwidatha ephantse yahlelwa, i-advanteji iyaba mxinwa kuba abaqikelelo baphatha iipateni kakuhle. Olona kuphumelela luza kwi-latency-sensitive applications njengeenkqubo zexesha langempela, ii-injini zemidlalo, kunye ne-high-frequency data processing apho yonke i-microsecond ye-pipeline esebenzayo ibala.

Ngaba ndingasebenzisa ubuchule obungenasebe kwiiprojekthi zam?

Ngokuqinisekileyo. Iipateni ezingenasebe zisebenza kwi-C, C++, Rust, kunye namaxesha okusebenza eJavaScript. Qala ngokutshintsha iimeko ezilula ngezibalo ezilinganayo—umzekelo, usebenzisa (a > b) * a + (a <= b) * b endaweni ye-if/else for max. Abaphuhlisi abasebenzisa i-platform ye-Mewayz banokuphonononga iimodyuli ezijoliswe ekusebenzeni kuzo zonke iimodyuli zayo ze-207 ezikhoyo, zonke zifikeleleke kwi-$ 19 / mo, ukudibanisa i-algorithms ephuculweyo kwimveliso yomsebenzi.

Ndingakuphepha nini ukuhlela okungenasebe?

Ukuhlela okungenasebe akusoloko lolona khetho lulungileyo. Kuluhlu oluncinci (phantsi kwe ~ 64 element), uhlobo lofakelo olunamasebe ludla ngokuphumelela ngenxa yentloko esezantsi. Xa idatha ihlelwa ikakhulu okanye ineepateni ezinokuqikelelwa, izibikezelo zesebe zifezekisa ukuchaneka okukufutshane-okugqibeleleyo, okwenza ukuba i-branchless overhead ingabi yimfuneko. Soloko uthelekisa nedata yakho yokwenyani phambi kokuba uzibophelele kwindlela engenamasebe-ukwenziwa kwangaphambi kwexesha ngaphandle kokwenza iprofayile kunokongeza ubunzima ngaphandle kwenzuzo enokulinganiswa.
