XNUMX. Misali

Don sanin ko tsarin ku yana ƙarƙashin nauyi mai nauyi, dole ne ku fahimci abin da matsakaicin nauyi ke nufi.

Na gaba,Chen WeiliangZa a yi bayanin wannan tambayar a cikin mafi kyawun harshe mai yiwuwa.

Na farko, muna ɗauka cewa a cikin mafi sauƙi, kwamfutarka tana da CPU guda ɗaya kawai, kuma dukkanin ayyuka dole ne a yi ta wannan CPU.

Bari mu yi tunanin Matsakaicin nauyin wannan CPU a matsayin gada:

Hanya daya ce kacal a kan gadar kuma dole ne dukkan motocin su ketare wannan layin.

(Tabbas, gadar za a iya amfani da ita kawai a hanya ɗaya.)

Lokacin da nauyin tsarin ya kasance 0, yana nufin babu mota a kan gada ▼

Nauyin tsarin shine 0.5, wanda ke nufin akwai rabin motocin akan gada ▼

Nauyin tsarin shine 1.0, wanda ke nufin akwai motoci akan dukkan sassan gadar, wanda ke nufin gadar ta "cika" ▼

• Amma dole ne a nuna cewa har yanzu ana iya wuce gadar a nan lafiya.

Nauyin tsarin shine 1.7, wanda ke nufin akwai motoci da yawa kuma gada ta cika (100%).

• Motocin da ke jiran gadar sun kai kashi 70% na motocin gadar.

Ta hanyar kwatance, da sauransu, nauyin tsarin shine 2.0:

• Ma'ana akwai motoci da yawa da ke jira kamar yadda akwai gada.
• Nauyin tsarin 3.0 yana nufin akwai motocin da yawa da ke jira a kan gada kamar bene.
• Lokacin da nauyin tsarin ya fi 1, dole ne motar baya ta jira;
• Mafi girman nauyin tsarin, yana da tsayin lokacin jira don ketare gada▼

• Nauyin tsarin CPU daidai yake da ƙarfin gadar analog da aka ambata a sama, wanda shine matsakaicin nauyin aikin CPU.
• Motar da ke kan gada wani tsari ne da ke jiran CPU yayi aiki.

Idan CPU yana aiwatar da matsakaicin matakai 100 a cikin minti daya, nauyin tsarin shine 0.2, wanda ke nufin cewa CPU kawai yana aiwatar da matakai 1 a cikin wannan minti 20;

Nauyin tsarin 1.0 yana nufin cewa CPU tana ɗaukar matakai 1 a cikin wannan minti 100;

1.7 Wannan yana nufin cewa baya ga matakai 100 da CPU ke sarrafa, akwai matakai 70 da ake jira a sarrafa su ta CPU.

Domin gudanar da kwamfutar a hankali, nauyin tsarin bai kamata ya wuce 1.0 ba, don haka babu buƙatar jira kowane tsari kuma ana iya aiwatar da dukkan matakai da farko.

Babu shakka, 1.0 shine maɓalli mai mahimmanci.

Idan wannan ƙimar ta wuce, tsarin ba shi da kyau.Dole ne ku shiga tsakani.

XNUMX. Nawa ne matsakaicin nauyin nauyin tsarin ya dace?

Shin 1.0 shine madaidaicin ƙima don nauyin tsarin?

Ba lallai ba ne, sysadmins yakan bar sarari kaɗan.

Lokacin da wannan ƙimar ta kai 0.7, yakamata ku san wani abu kamar haka:

Hudu, masu sarrafa CPU da yawa

Abin da ke sama yana ɗauka cewa kwamfutarka (kwamfuta) tana da CPU guda ɗaya kawai.

Me zai faru idan kwamfutarka (kwamfuta) na da CPUs guda 2?

2 CPUs yana nufin cewa ikon sarrafa kwamfuta (kwamfuta) ya ninka sau biyu, kuma adadin hanyoyin da ake iya sarrafa su a lokaci guda suna ninka sau biyu.

Chen WeiliangHar yanzu ana amfani da gadar a matsayin misali a nan, 2 CPUs yana nufin cewa gadar tana da tashoshi 2, kuma ƙarfin zirga-zirga yana ninka sau biyu ▼

• Don haka, 2 CPUs yana nufin cewa nauyin tsarin zai iya kaiwa 2.0, kuma kowane CPU ya kai nauyin aiki 100%.
• Don kwamfuta mai n.0 CPUs, nauyin tsarin da aka yarda ya kai CPUs n.0.

Biyar, Multi-core CPU processor

Masu samar da guntu yawanci suna ƙunshe da maɓallan CPU masu yawa a cikin 1 CPU, wanda ake kira "Multi-core CPU".

Multi-core CPU yayi kama da Multi-CPU dangane da nauyin tsarin.

Don haka, lokacin la'akari da nauyin tsarin, dole ne ku yi la'akari da yawan CPUs da kwamfutarku ke da su?Kuma guda nawa kowanne CPU ke da shi?

Sannan, ta hanyar rarraba tsarin tsarin da jimlar keɓantuttukan tsakiya, muddin nauyin da ke nauyin ba ya wuce 1.0, kwamfutar zata wuce kamar yadda aka saba.

Yadda za a san adadin CPU cores na kwamfuta?
