This article mainly introduces the Linux kernel how to achieve multi-core mode, the article is very detailed, has a certain reference value, interested friends must read it!

In today's Microsoft Windows 7 popular, do you still insist on using the Linux operating system? If you are a regular user of the Linux operating system. The problems explained here will help you with your Linux kernel. The name of the Linux kernel is also Linux. At the time of installation, the customer does not choose to install kernel-smp, the system will be installed as a single processor core by default, and users can upgrade the system by adding multi-processor core modules.

Specific steps:

1. Start Red Hat Linux as 4, log in as root, and enter the character interface.

2. Extract the kernel-smp-2.2.14-5.0.i386.rpm package (many methods can be used to directly decompress the CD-ROM drive, or copy the contents of the CD-ROM drive to a shared directory)

# rpm-- install kernel-smp-2.2.14-5.0.i386.rpm to load the multiprocessor (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 multiprocessor boot options, such as

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, and after "boot:" appears, type "smp" to enter the multiprocessor core.

So you know the Linux kernel.
