To not forget anymore…. All the new CPU support the 64 bit architecture. But If I have an almost-old CPU ? How can I check ?
…using the command lscpu.
[root@localhost ~]# lscpu Architecture: i686 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 CPU socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 15 Stepping: 13 CPU MHz: 1995.167 BogoMIPS: 3989.80 L1d cache: 32K L1i cache: 32K L2 cache: 2048K NUMA node0 CPU(s): 0,1
The line to look is CPU op-mode(s).
