Ukuze unike amandla ukubuka kochungechunge kokuphumayo okuphezulu, ncenga phezulu ngenketho ethi “-H”. Lokhu kuzoklelisa yonke imicu ye-Linux. Ungaphinda uvule noma uvale imodi yokubuka intambo ngenkathi i-top isebenza, ngokucindezela inkinobho ethi 'H'. Qaphela ukuthi esibonelweni esingenhla inani lemicu kusistimu lifakwe kanjani ohlwini.
Mingaki imicu enginayo i-Linux?
Uzothola ukuthi zingaki izintambo ongazisebenzisa emshinini wakho ngokusebenzisa i-htop noma i-ps command ebuyisela inombolo yenqubo emshinini wakho. Ungasebenzisa ikhasi lomuntu mayelana nomyalo we-'ps'. Uma ufuna ukubala inombolo yazo zonke izinhlelo zabasebenzisi, ungasebenzisa owodwa wale miyalo: ps -aux| wc -l.
Ngiyibheka kanjani imicu?
Ukubuka imicu ngenqubo nge-Process Explorer, khetha inqubo bese uvula izakhiwo zenqubo (chofoza kabili kunqubo noma uchofoze Into yemenyu Inqubo, Izakhiwo). Bese uchofoza kuthebhu ethi Imicu. Le thebhu ibonisa uhlu lochungechunge lwenqubo kanye namakholomu amathathu olwazi.
Mingaki imicu eminingi kakhulu?
Uma ukusetshenziswa kwakho kwentambo kufinyelela ku-3, kusho ukuthi i-100 inkulu kakhulu. Uma ihlala ku-100 isikhathi esiningi sosuku, iqhume ifike ku-200 futhi ubone ukuthi kwenzekani.
Mingaki imicu esetshenziswa imidlalo ngo-2020?
Ungathengi lutho olunemicu engaphansi kwe-16 ngo-2020. Lokho ngokuvamile kusho ama-cores angu-8 nemicu engu-16. Isizathu salokhu ukuthi ama-consoles amasha kakhulu kulindeleke ukuthi abe nama-CPU wentambo ayi-16. Lokhu kusho ukuthi imidlalo kusuka ngo-2020 kuya phambili izothuthukiswa kangcono kakhulu kuyo.
Ihlelwa kanjani imicu ku-Linux?
I-Linux isebenzisa i-algorithm ye-Completely Fair Scheduling (CFS), ewukuqaliswa komugqa olungile onesisindo (WFQ). Cabanga ngesistimu ye-CPU eyodwa ongaqala ngayo: Isikhathi se-CFS sisika i-CPU phakathi kwemicu esebenzayo. Kunesikhawu sesikhathi esimisiwe lapho uchungechunge ngalunye ohlelweni kufanele lusebenze okungenani kanye.
Ngabe inqubo inamachungechunge amangaki?
Inqubo ingaba nanoma yikuphi ukusuka kuchungechunge olulodwa kuya emicu eminingi. Lapho inqubo iqala, inikezwa inkumbulo nezinsiza. Uchungechunge ngalunye lwenqubo lwabelana ngaleyo nkumbulo nezinsiza. Ezinqubweni ezinomucu owodwa, inqubo iqukethe intambo eyodwa.
Ingabe imicu ithola eyabo i-PID?
Ku-kernel, intambo ngayinye ine-ID yayo, ebizwa ngokuthi i-PID, nakuba kungase kube umqondo owengeziwe ukubiza lokhu nge-TID, noma i-ID yentambo, futhi bane-TGID (ID yeqembu lezintambo) okuyi-PID yokuqala. intambo eyadalwa ngenkathi inqubo idalwa.
Ithini inombolo efanelekile yochungechunge?
Ngokufanelekile isamba sokubala sentambo yayo yonke imisebenzi kufanele kube inombolo yamacores wesistimu, ngaphandle kwakumasistimu asekela i-hyper-threading, lapho kufanele ibe kabili inani lama-cores. Ngakho-ke uma isistimu ingenayo i-hyper-threading, kunezibalo ezingu-8 ezisebenzayo, ngayinye kufanele isebenze ngochungechunge olulodwa.
Mingaki imicu ephezulu ongayidala?
Ku-32-bit JVM, usayizi wesitaki ubonakala ukhawulela inani lemicu ongayidala. Lokhu kungase kube ngenxa yesikhala samakheli esilinganiselwe.
...
Ukudala imicu kubanensa.
| Ukuluma | Usayizi Wesitaki | Imicu eminingi |
|---|---|---|
| I-64-bit | 128K | 32,072 |
| I-64-bit | 512K | 32,072 |
Ingabe kungcono ukuba nama-cores amaningi noma imicu?
I-CPU enikeza ama-cores amaningi noma i-hyper-threading ingase isebenze kangcono kakhulu kune-single-core CPU yejubane elifanayo elingafaki i-hyper-threading. Futhi ama-PC anama-CPU amaningi angaba nenzuzo enkulu nakakhulu.
Ingabe ama-cores angu-6 nemicu engu-12 yanele?
Ukuba nama-cores ayi-6 kuphela, anamandla kakhulu kunemicu eyi-12 iyodwa, uzothola imiphumela engcono emidlalweni eminingi yanamuhla (hhayi okuningi) njengoba abathuthukisi bebukeka bengathuthukisi kahle ukusebenza uma usebenzisa izintambo, kepha iphrosesa izokwenza. ukwazi ukuhlala isikhathi eside futhi wenze kangcono emidlalweni ezayo.
Ingabe imicu engu-4 core 8 yanele ukusakaza?
Ngokudlala, uzodinga ubuncane be-quad-core okungama-CPU cores angu-4 kanye nesishiyagalombili noma ngaphezulu kumageyimu afakwe amakhodi ochungechunge oluphezulu. Ukuze usakaze thola iphrosesa ye-CPU enomongo onengqondo futhi esekela ukusebenza kwe-GPU ukuze uthole ukuzizwisa okuhamba phambili kwegeyimu nokulungiselelwa kwe-PC yokudlala.
Ingabe imicu emi-4 yanele ukudlala?
Emuva embuzweni wakho wasekuqaleni, yebo ama-cores angu-4 *anele* amageyimu njengamanje. Ungathola ukusebenza okungcono kwezinye izihloko (futhi ngokusobala nezinye izihloko kumamephu ahlukahlukene) nge-Cpu enemicu eminingi ephezulu. Kodwa-ke, nge-Gpu enhle ngokwanele, ama-cores ama-4 anela ngokwanele. Lokhu kuyiqiniso kuma-80% okwakhiwa kwabadlali bamageyimu.
