CpuSet is small C-written application providing a frontend to mechanism for assigning a set of CPUs and Memory
|
|
|
|
Nodes to a set of tasks. Cpusets constrain the CPU and Memory placement of tasks to only the resources within
|
|
|
|
a task's current cpuset by utilizing a cgroups mechanism.
|
|
|
|
|
|
|
|
This small application is designed to be used with QEMU. Available arguments:
|
|
|
|
* -e: Enables the 'host' cgroup and moves all possible tasks into it, except the parent process. Thanks to that,
|
|
|
|
the console stays at root group and allows to launch qemu outside of the group with limited resources.
|
|
|
|
* -d: Disabled to 'host' group and reverts all changes.
|
|
|
|
* -c: Specifies the CPU cores assigned for 'host' group
|
|
|
|
* -m: Memory Node assigned for 'host' group

## Usage Example
|
|
|
|
#!/bin/sh
|
|
|
|
cpuset -e -c 0-1,8-9 -m 0
|
|
|
|
qemu-system-x86_64 (...)
|
|
|
|
cpuset -d
|
|
|
|
|
|
|
|
If script is not being launched as root, cpuset binary needs to have SETUID enabled!
