Top / numactl
Control NUMA policy for processes or shared memory
usage: numactl [--all | -a] [--interleave= | -i <nodes>] [--preferred= | -p <node>]
[--physcpubind= | -C <cpus>] [--cpunodebind= | -N <nodes>]
[--membind= | -m <nodes>] [--localalloc | -l] command args ...
numactl [--show | -s]
numactl [--hardware | -H]
numactl [--length | -l <length>] [--offset | -o <offset>] [--shmmode | -M <shmmode>]
[--strict | -t]
[--shmid | -I <id>] --shm | -S <shmkeyfile>
[--shmid | -I <id>] --file | -f <tmpfsfile>
[--huge | -u] [--touch | -T]
memory policy | --dump | -d | --dump-nodes | -D
memory policy is --interleave | -i, --preferred | -p, --membind | -m, --localalloc | -l
<nodes> is a comma delimited list of node numbers or A-B ranges or all.
Instead of a number a node can also be:
netdev:DEV the node connected to network device DEV
file:PATH the node the block device of path is connected to
ip:HOST the node of the network device host routes through
block:PATH the node of block device path
pci:[seg:]bus:dev[:func] The node of a PCI device
<cpus> is a comma delimited list of cpu numbers or A-B ranges or all
all ranges can be inverted with !
all numbers and ranges can be made cpuset-relative with +
the old --cpubind argument is deprecated.
use --cpunodebind or --physcpubind instead
<length> can have g (GB), m (MB) or k (KB) suffixes
