Tag nrho lub tswv yim qab Parallel . ForEach () yog hais tias koj muaj ib txheej ntawm threads thiab txhua threads txheej txheem ib feem ntawm kev sau. Raws li koj pom, qhov no tsis ua haujlwm nrog async - tos, qhov twg koj xav tso xov rau lub sij hawm ntawm lub async hu. ForEach (), uas txhawb nqa asynchronous Task s zoo.
Hais txog qhov no, yuav ua li cas koj tos rau parallel foreach kom tiav?
Koj tsis tas yuav ua dab tsi tshwj xeeb, Parallel . Foreach () yuav tos mus txog rau tag nrho nws cov hauj lwm ceg ua kom tiav . Los ntawm kev hu xov tooj koj tuaj yeem kho nws li ib nqe lus synchronous thiab piv txwv li qhwv nws hauv sim / ntes. Koj tsis xav tau nrog Parallel.
Ib yam li ntawd, yog foreach asynchronous? Nws tsis yog asynchronous . Nws yog thaiv. Cov neeg uas thawj zaug kawm ib hom lus xws li Java, C, lossis Python ua ntej lawv sim JS yuav tsis meej pem thaum lawv sim tso qhov kev txiav txim siab ncua lossis API hu rau hauv lawv lub voj voog.
Dhau li ntawm no, ua li cas koj txuas ntxiv mus rau qhov sib npaug?
Thaum koj hloov koj lub voj mus rau hauv lub ntsiab txhais tau zoo rau lub Parallel . Foreach logic, koj tau mus ua cov lus lub cev lambda. Zoo, qhov ntawd yog ib qho kev ua uas tau hu los ntawm tus Parallel muaj nuj nqi. Yog li, hloov txuas ntxiv nrog rov qab, thiab tawg nrog Stop() lossis Break() nqe lus.
Puas yog txoj hauj lwm Thaum Txhua qhov sib luag?
Daim ntawv thov ntawm Thaum Tag Nrho rov ib leeg txoj hauj lwm uas tsis tiav kom txog rau thaum txhua txoj hauj lwm nyob rau hauv kev sau ua tiav. Cov hauj lwm zoo li khiav hauv thaum uas tig mus , tab sis tsis muaj xov ntxiv yog tsim. Cov hauj lwm tuaj yeem ua tiav hauv txhua qhov kev txiav txim.

Koj puas tuaj yeem xaim qhov hluav taws xob nyob rau hauv parallel?
Nws yog ib qho uas yuav piav txog cov khoom siv phab ntsa hauv tsev uas tau xaim ua ke siv cov khoom siv terminals li wired hauv series. Tab sis, qhov tseeb, tag nrho cov khoom siv hauv tsev yog ib txwm xaim nyob rau hauv tib lub sijhawm, thiab tsis nyob hauv koob. Nyob rau hauv ib lub voj voog, tam sim no yuav tsum dhau los ntawm kev thauj khoom ntawm txhua lub cuab yeej
Parallel Python yog dab tsi?
Parallel Python yog ib qho python module uas muab cov txheej txheem rau kev ua kom zoo sib xws ntawm python code ntawm SMP (cov kab ke nrog ntau lub processors lossis cores) thiab pawg (cov khoos phis tawj txuas nrog network). Nws yog lub teeb, yooj yim rau nruab thiab koom ua ke nrog lwm cov python software
Puas yog NUnit cov kev xeem khiav nyob rau hauv parallel?
Lub NUnit 3.0 lub moj khaum tuaj yeem khiav cov kev xeem sib npaug hauv kev sib dhos. Qhov no yog qhov chaw sib cais tag nrho los ntawm Cav Parallel Test Execution, txawm hais tias nws muaj peev xwm siv ob qho tib si hauv tib qhov kev xeem khiav. Los ntawm lub neej ntawd, tsis muaj qhov sib luag ua tiav
Puas yog kev cog lus async?
Async functions siv ib tug implicit Promise rov qab nws cov txiaj ntsig. Txawm hais tias koj tsis xa rov qab cov lus cog tseg kom meej meej async muaj nuj nqi ua kom koj cov cai dhau los ntawm kev cog lus. tos tsuas yog thaiv cov lej ua tiav hauv async muaj nuj nqi. Nws tsuas yog ua kom paub tseeb tias kab tom ntej raug ua tiav thaum cov lus cog tseg
Parallel ForEach C# yog dab tsi?
Foreach voj nyob rau hauv C # sau raws li ib tug xov tooj thiab kev ua yuav ua tau ib tug sequentially ib los ntawm ib tug. Foreach voj yog qhov tseem ceeb ntawm C# thiab nws muaj los ntawm C# 1.0. Nws qhov kev ua tiav qeeb dua li Parallel
