서버 접속하셔서
cat /proc/cpuinfo
cat /proc/meminfo
fdisk -l
확인하시면 됩니다.
추가 Cpu 조사
할 때 좀더 상세히
Cpu 개수와 core 개수가 헷갈리신다면
해당 cat
/proc/cpuinfo 하시면 physical id 가 나옵니다.
예) physical id : 0 0번이 4개 있으면 즉 종류가 1종류
이 값이 1종류
라면 실제 물리적 cpu개수는 1개라는 뜻입니다.
Cpu core 수는
예) cpu cores :
4 요런 형식으로 나오구요 코어는 4개가 되겠조?
즉각 개수 파악 명령어
cat /proc/cpuinfo |
grep "physical id" | uniq -dc | wc -l
추가로 간혹~! 좋은 cpu 일때 processor 개수가 실제 core 수랑 맞지 않는 경우도 있습니다.
이 경우는
siblings : 4 == 즉 동기
cores가 4개인데
siblings 값은 8이면 즉
HyperThread 라는 뜻입니다.그게 아니라면
둘다 값이 똑같겟조?
요렇게 파악 하시면 됩니다.
하드 개수 파악은
fdisk –l
으로 파악 하시면 됩니다.!
개수 및 용량이 나오겟조 ^^~
추가
1) Physical ID = Number assigned to each Processor on MotherBoard
2) Sibling ID = Number of logical processor provided by each Physical Processor
3) Core ID = Number of core in the Physical Processor
Note: If core Id is equal to sibling ID it means there is no Hyperthreading
If sibling ID is double that of core ID it supports Hyperthreading
Command: cat /proc/cpuinfo
Case 1:
Single-processor, Single-core, HT
processor 0 1
physical id 0 0
siblings 2 2
core id 0 0
cpu cores 1 1
The cpu cores value is "1", so this system uses single-core processors.
The cpu cores value does not match the siblings value, so this system has hyperthreading.
There is one physical id listed, so this is a single-processor, single-core system with hyperthreading.
Case 2:
Single-processor, Dual-core, non-HT
processor 0 1
physical id 0 0
siblings 2 2
core id 0 1
cpu cores 2 2
The cpu cores value is "2" so the system uses dual-core processors.
The cpu cores value matches the siblings value, so this system does not have hyperthreading.
There is one physical id listed, so this is a single-processor, dual-core system without hyperthreading.
Case 3:
Dual-processor, Dual-core, HT
processor 0 1 2 3 4 5 6 7
physical id 0 0 0 0 1 1 1 1
siblings 4 4 4 4 4 4 4 4
core id 0 0 1 1 0 0 1 1
cpu cores 2 2 2 2 2 2 2 2
The cpu cores value is "2" so this system uses dual-core processors.
The cpu cores value does not match the siblings value, so this system has hyperthreading.
There are two physical IDs listed, so this is a dual-processor, dual-core machine with hyperthreading
Case 4:
Dual-processor, Quad-core, non-HT
processor 0 1 2 3 4 5 6 7
physical id 0 1 0 1 0 1 0 1
siblings 4 4 4 4 4 4 4 4
core id 0 0 1 1 2 2 3 3
cpu cores 4 4 4 4 4 4 4 4
The cpu cores value is "4", so the system uses quad-core processors.
The cpu cores value matches the siblings value, so this system does not have hyperthreading.
There are two physical IDs listed, so this is a dual-processor, quad-core system without hyperthreading
Case 5:
Dual-processor, Quad-core, HT
processor 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
physical id 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1
siblings 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8
core id 0 0 1 1 2 2 3 3 0 0 1 1 2 2 3 3
cpu cores 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
The cpu cores value is "4", so the system uses quad-core processors.
The cpu cores value does not match the siblings value, so this system has hyperthreading.
There are two physical IDs listed, so this is a dual-processor, quad-core system with hyperthreading.
