In order to improve the colocation effect on CentOS 7.9 operating system kernel in the CPU resource dimension, Anolis community provides a plug-in solution, which is to use the plugsched to provide a scheduler plug-in package for CPU colocation technology. This plug-in can be directly installed on CentOS 7.9 without downtime and business migration. For more details about plugsched, please refer to the Blog.
- Kernel: The kernel must be the official CentOS 7.9 kernel.
- version == 3.10.0
- release >= 1160.81.1
Install the plug-in
# rpm -ivh https://github.com/koordinator-sh/koordinator/releases/download/v1.1.1/scheduler-bvt-noise-clean-$(uname -r).rpm
If you update the kernel version, you can use the following command to install the new plug-in.
# rpm -ivh https://github.com/koordinator-sh/koordinator/releases/download/v1.1.1/scheduler-bvt-noise-clean-$(uname -r).rpm --oldpackage
After installation, you can see the
cpu.bvt_warp_ns in cpu cgroup directory and the usage of it is compatible with Group Identity.
Removing the plug-in can use the
rpm -e command and the
cpu.bvt_warp_ns doesn't exist either. Please make sure that no tasks are still using
cpu.bvt_warp_ns before uninstalling.
Use Koordinator CPU QoS feature
