Hello, In http://linuxrealtime.org/index.php/Improving_the_Real-Time_Properties#chapter331 there is information how to isolate rt and non rt tasks. It says: " Now it is possible to run a real-time task in the real-time partition: 1. $ echo pid_of_task > /sys/fs/cgroup/cpusets/rt/tasks Since we have an RT partition with more then one CPU we might want to choose a specific CPU to run on. 2. Change the task affinity to only include CPU3 in the real-time partition: $ taskset -p 0x8 pid_of_task ... 3. This is how the non-isolated benchmark was executed: $ ./stress -d 4 --hdd-bytes 20M -c 4 -i 4 -m 4 --vm-bytes 15M & $ ./cyclictest -m -p 99 -l 300000 -q; " If only in step 3 we run the RT threads (in cyclictest), how can we know aleady in step 1, and step 2, what is the pid_of_task ? Thank you, Ran
