5. Taskset and Processor Sets: On some Linux systems, the “taskset” command can also be used in conjunction with processor sets (psets). Processor sets allow system administrators to group CPU cores together and assign them to specific processes. The “taskset” command can be used to bi...
taskset - Unix, Linux Command - taskset is used to set or retrieve the CPU affinity of a running process given its PID or to launch a new COMMAND with a given CPU affinity. CPU affinity is a scheduler property that bonds a process to a given set of CPUs
let i=0 for PID inPIDS;doCPU=PIDS;doCPU=(echo “$i % $CPUS” | bc) taskset -pc $CPU $PID let i++ done
let i=0 for PID inPIDS;doCPU=PIDS;doCPU=(echo “$i % $CPUS” | bc) taskset -pc $CPU $PID let i++ done
Unsurprisingly, it uses the command: top The names of all running commands are on the right side of the screen. The corresponding Process IDs are on the left. Write down your PID as you’ll use it in a moment. For this example, we’ll use VLC, which is in the middle of playing a...
In summary, taskset is a useful tool for managing the CPU affinity of processes on a Linux system. It can help you optimize the performance of your system by dedicating specific CPU cores to specific processes. More information about the command can be found in the manual page by typing “...
Our benchmark tasks must be modified to add a taskset command to pin the CPU the benchmark will run on. This is needed because now CPUs come with performance cores and energy efficient cores, making it harder to have reliable results oth...

一、在Linux上修改进程的“CPU亲和力” 在Linux上,可以通过taskset命令进行修改。以Ubuntu为例,运行如下命令可以安装taskset工具。 # apt-get install schedutils 对运行中的进程,文档上说可以用下面的命令,把CPU#1 #2 #3分配给PID为2345的进程: # taskset -cp 1,2,3 2345 ...
