Deadlock yog ib qho xwm txheej uas txheej txheej txheej txheem raug thaiv vim tias txhua tus txheej txheem tuav cov peev txheej thiab tos lwm qhov peev txheej tau txais los ntawm qee qhov txheej txheem. Tuav thiab Tos: Ib txheej txheem tuav tsawg kawg ib qho peev txheej thiab tos cov peev txheej.
Hauv qhov no, piv txwv txog kev tuag yog dab tsi?
Ib txheej txheej txheem los yog xov yog tuag lawm thaum txhua tus txheej txheem lossis xov yog tos kom muaj peev txheej tau tso tawm uas yog tswj hwm los ntawm lwm cov txheej txheem. Ntawm no yog ib qho piv txwv ntawm qhov xwm txheej qhov twg kev tuag tuaj yeem tshwm sim. Ob txoj xov yog thaiv; txhua tus tab tom tos qhov xwm txheej uas yuav tsis tshwm sim.
Ib yam li ntawd, dab tsi yog deadlock koj yuav ua li cas zam nws? Deadlocks tuaj yeem tiv thaiv los ntawm kev tiv thaiv tsawg kawg yog ib qho ntawm plaub yam uas yuav tsum tau muaj:
- 7.4.1 Kev Sib Koom Tes. Cov peev txheej sib koom xws li cov ntaub ntawv nyeem nkaus xwb tsis ua rau muaj kev tuag.
- 2 Tuav thiab Tos.
- 3 Tsis muaj preemption.
- 4 Lub voj voog tos.
Kuj Paub, dab tsi yog deadlock thiab nws hom?
Ob hom ntawm kev tuag tuaj yeem txiav txim siab: 1. Cov peev txheej Deadlock . tshwm sim thaum cov txheej txheem tab tom sim kom nkag mus rau cov khoom siv tshwj xeeb, cov ntaub ntawv, xauv, servers, lossis lwm yam kev pabcuam. Hauv Resource kev tuag qauv, ib txheej txheem tos kom txog thaum nws tau txais tag nrho cov peev txheej uas nws tau thov.
Dab tsi yog deadlock piav qhia txog kev tiv thaiv kev tuag?
Hauv computer science, kev tiv thaiv kev tuag algorithms yog siv nyob rau hauv concurrent programming thaum ntau cov txheej txheem yuav tsum tau txais ntau tshaj ib qho kev sib koom. A kev tiv thaiv kev tuag algorithm npaj cov peev txheej siv los ntawm txhua tus txheej txheem los xyuas kom meej tias yam tsawg kawg ib txheej txheem ib txwm muaj peev xwm tau txais tag nrho cov peev txheej uas nws xav tau.
