linux如何查看cpu核數(shù)
當(dāng)我的linux系統(tǒng)想要查看下cpu的核數(shù)!用什么方法好呢?下面由學(xué)習(xí)啦小編給你做出詳細(xì)的linux查看cpu核數(shù)方法介紹!希望對(duì)你有幫助!
linux查看cpu核數(shù)方法一
1.查看邏輯CPU個(gè)數(shù):
#cat /proc/cpuinfo |grep "processor"|sort -u|wc -l
24
2.由于有超線程技術(shù)有必要查看一下物理CPU個(gè)數(shù):
#grep "physical id" /proc/cpuinfo|sort -u|wc -l
2
#grep "physical id" /proc/cpuinfo|sort -u
physical id : 0
physical id : 1
查看每個(gè)物理CPU內(nèi)核個(gè)數(shù):
#grep "cpu cores" /proc/cpuinfo|uniq
cpu cores : 6
每個(gè)物理CPU上邏輯CPU個(gè)數(shù):
#grep "siblings" /proc/cpuinfo|uniq
siblings : 12
判斷是否開(kāi)啟了抄超線程:
如果多個(gè)邏輯CPU的"physical id"和"core id"均相同,說(shuō)明開(kāi)啟了超線程
或者換句話說(shuō)
邏輯CPU個(gè)數(shù) > 物理CPU個(gè)數(shù) * CPU內(nèi)核數(shù) 開(kāi)啟了超線程
邏輯CPU個(gè)數(shù) = 物理CPU個(gè)數(shù) * CPU內(nèi)核數(shù) 沒(méi)有開(kāi)啟超線程

當(dāng)我的linux系統(tǒng)想要查看下cpu的核數(shù)!用什么方法好呢?下面由學(xué)習(xí)啦小編給你做出詳細(xì)的linux查看cpu核數(shù)方法介紹!希望對(duì)你有幫助!
linux查看cpu核數(shù)方法一
1.查看邏輯CPU個(gè)數(shù):
#cat /proc/cpuinfo |grep "processor"|sort -u|wc -l
24
2.由于有超線程技術(shù)有必要查看一下物理CPU個(gè)數(shù):
#grep "physical id" /proc/cpuinfo|sort -u|wc -l
2
#grep "physical id" /proc/cpuinfo|sort -u
physical id : 0
physical id : 1
查看每個(gè)物理CPU內(nèi)核個(gè)數(shù):
#grep "cpu cores" /proc/cpuinfo|uniq
cpu cores : 6
每個(gè)物理CPU上邏輯CPU個(gè)數(shù):
#grep "siblings" /proc/cpuinfo|uniq
siblings : 12
判斷是否開(kāi)啟了抄超線程:
如果多個(gè)邏輯CPU的"physical id"和"core id"均相同,說(shuō)明開(kāi)啟了超線程
或者換句話說(shuō)
邏輯CPU個(gè)數(shù) > 物理CPU個(gè)數(shù) * CPU內(nèi)核數(shù) 開(kāi)啟了超線程
邏輯CPU個(gè)數(shù) = 物理CPU個(gè)數(shù) * CPU內(nèi)核數(shù) 沒(méi)有開(kāi)啟超線程
