Chii chinonzi branchless sorting uye nei zvine basa?

Kuronga zvisina bazi kunobvisa mapazi anemiganho (kana/zvimwe zvirevo) kubva pakuenzanisa mashandiro, zvichibvumira pombi yeCPU kuita pasina zvirango zvekusafungira. Ma processor emazuva ano anovimba nekufanotaura kwebazi, uye kana fungidziro ikatadza, pombi inomira. Madhizaini asina bazi anoshandisa masvomhu semafambisirwo ane mafambisirwo ekuita kuti data rirambe richiyerera zvakanaka, zvichikonzera nguva yekuronga nekukurumidza pamaseti makuru kana asingafungidzike.

Kuronga zvisina bazi kunomhanya zvakadii kana zvichienzaniswa nemaitiro echinyakare?

Kubudirira kwemaitiro kunoenderana nehunhu hwedata, asi kurongedza pasina bazi kunogona kuita 2–5x nekukurumidza pane zvisina tsarukano kana zveanopikisa apo kufanotaura kwebazi kunokundikana kazhinji. Pa data rinenge rakarongedzwa, mukana wacho unoderera sezvo vanofanotaura vachibata mapatani zvakanaka. Iko kuhwina chaiko kunouya mune latency-sensitive application senge-chaiyo-nguva masisitimu, injini dzemitambo, uye yakakwirira-frequency data processing apo yega yega microsecond yepombi inoshanda zvakanaka.

Ndingashandisa nzira dzisina bazi kumapurojekiti angu here?

Chokwadi. Mapaiti asina bazi anoshanda muC, C++, Rust, uye kunyange optimized JavaScript runtimes. Tanga nekutsiva zvimiso zvakapfava nemasvomhu akaenzana—somuenzaniso, kushandisa (a > b) * a + (a <= b) * b panzvimbo pekuti if/else for max. Vagadziri vachishandisa Mewayz papuratifomu vanogona kuongorora maitiro-akatarisana mamodules mukati mayo mazana maviri nenomwe anowanikwa mamodule, ese anowanikwa pamadhora gumi nemapfumbamwe / mo, kubatanidza akagadziridzwa algorithms mukugadzira workflows.

Ndirini pandinofanira kudzivirira kusarongeka kusina branch?

Kuronga zvisina bazi haisiriyo sarudzo yakanaka nguva dzose. Kune madiki arrays (pasi ~ 64 element), yekuisa mhando nemapazi kazhinji inokunda nekuda kwekudzika pamusoro. Kana data ichinyanya kurongedzwa kana kuti ine maitiro anofanotaurwa, fungidziro yebazi inosvika pedyo-yakakwana, ichiita isina bazi kumusoro kusakosha. Gara uchienzanisa nedata rako chairo usati wazvipira kune imwe nzira isina bazi- kukurumidza optimization pasina profiling kunogona kuwedzera kuomarara pasina kuyerwa pfuma.
