How to display multi-core mode in Linux

Article Title: how to display multi-core mode in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

During installation, the client does not choose to install kernel-smp. The system is installed as a single-processor core by default. You can upgrade the system by adding a multi-processor core module.

Procedure:

1. Start Red Hat Linux as 4 and Log On as root to enter the character interface.

2, unzip the kernel-smp-2.2.14-5.0.i386.rpm package, (a lot of methods can enter the drive directly decompress, you can also copy the drive to the shared directory)

# Rpm -- install the kernel-smp-2.2.14-5.0.i386.rpm to load the multi-processor (smp) module.

3. # mkinitrd-v-f/boot/initrd-2.2.14-5.0smp.img 2.2.14-5.0smp, create the initialization program.

4. # vi/etc/lilo. conf, add the multi-processor startup option, for example

Image =/boot/vmlinuz-2.2.14-5.0smp

Label = smp

Initrd =/boot/initrd-2.2.14-5.0smp.img

Read-only

Root =/dev/sda2

5. # lilo-v: restart the machine. After "boot:" appears, type "smp" and press enter to enter the multi-processor core.
