Long output (-l)
The -l option displays a long format listing with the following additional fields:
FREE CPU LIST
List of free CPUs in the cpuset
For example:
0-2
NFREECPUS ON EACH NODE
Number of free CPUs on each node
For example:
2/0,1/1
STATIC CPUSETS
List of static cpuset names
For example:
NO STATIC CPUSETS
CPU_RADIUS
Available CPUs with a given radius. CPU radius is determined by the processor
topology of the system and is expressed in terms of the number of router hops
between CPUs. The CPU radius is displayed as a comma-separated list of the
number of free CPUs available with radius 0, radius 1, radius 2, and so on:
For example:
2,3,3,3,3,3,3,3
✧ 2 CPUs are available within radius 0
✧ 3 CPUs are available within radius 1, 2, 3, 4, 5, 6, and 7.
CPUs grouped within a smaller radius can be thought of as being closer
together and therefore have better communications performance.
