Parallel Python yog a python module uas muab mechanism rau thaum uas tig mus kev ua ntawm python code ntawm SMP (cov kab ke nrog ntau lub processors lossis cores) thiab pawg (cov khoos phis tawj txuas nrog lub network). Nws yog lub teeb, yooj yim rau nruab thiab sib xyaw nrog lwm yam python software.

Ib yam li ntawd, nws raug nug, dab tsi yog qhov sib npaug ntawm kev suav hauv Python?

Parallel processing yog hom kev ua haujlwm uas cov haujlwm tau ua tiav ib txhij hauv ntau lub processors hauv tib lub computer. Nws yog txhais tau tias kom txo tag nrho ua sij hawm. Hauv python , multiprocessing module yog siv los khiav ywj siab thaum uas tig mus cov txheej txheem los ntawm kev siv subprocesses (tsis yog threads).

Python puas tuaj yeem ua haujlwm sib luag? Khiav Function hauv Parallel nrog Python Ua ntej, koj tuaj yeem ua tiav ua haujlwm hauv thaum uas tig mus siv lub multiprocessing module. Qhov thib ob, lwm txoj hauv kev rau cov txheej txheem yog cov xov. Technically, cov no yog cov txheej txheem sib sib zog nqus, thiab nyob sab nraud ntawm cov kab lus no.

Tsis tas li ntawd, qhov piv txwv ntawm kev ua vaj huam sib luag yog dab tsi?

Parallel processing yog lub peev xwm ntawm lub hlwb ua ntau yam (aka, txheej txheem) ib zaug. Rau piv txwv , thaum ib tug neeg pom ib yam khoom, lawv tsis pom ib yam, tab sis ntau yam sib txawv uas ua ke pab tus neeg txheeb xyuas qhov khoom tag nrho.

Puas yog multithreading ua tau hauv python?

Python puas muaj built-in tsev qiv ntawv rau feem ntau concurrent programming constructs - multiprocessing thiab multithreading . Tej zaum koj yuav xav tias, txij li thaum Python txhawb ob leeg, vim li cas Jein? Yog vim li cas, multithreading hauv Python tsis yog tiag multithreading , vim GIL Python.
