The above command returned the following output: pid 2363's current affinity mask: 3. So hexadecimal value '3' here means the process can run on any of the 4 processor cores: 0,1,2,3. If you want the output to be in terms of CPU range, you can add the -c command line option.

WebAug 1, 2024 · I find the use case invalid. If the user specifies NUMAMask=, it's the kernel scheduler's job to balance tasks so that they converge to the CPUs closest to the used memory (if you don't observe that despite CONFIG_NUMA_BALANCING, then it's possibly a bug).. Note that there can be CPU-less NUMA nodes making the proposed semantics … WebApr 23, 2024 · 1. Remove the cpu that you want to dedicate for your realtime process, using the kernel boot parameter isolcpus: Remove the specified CPUs, as defined by the cpu_number values, from the general kernel SMP balancing and scheduler algroithms. The only way to move a process onto or off an "isolated" CPU is via the CPU affinity syscalls. religious uprising meaning

WebNov 28, 2016 · taskset is used to set or retrieve the CPU affinity of a running pro cess 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 on the system. The Linux scheduler will honor the given CPU affinity and the process will not run on any other CPUs.
