Distribute n
items over the topology under root
.
Array cpuset
will be filled with n
cpusets distributed linearly over the topology under root
.
This is typically useful when an application wants to distribute n
threads over a machine, giving each of them as much private cache as possible and keeping them locally in number order.
The caller may typicall want to additionally call hwloc_cpuset_singlify() before binding a thread, so that it doesn't move at all.
