Detailed Description

       Hwloc uses bitmaps to represent two distinct kinds of object sets: CPU sets
       (hwloc_cpuset_t) and NUMA node sets (hwloc_nodeset_t). These types are both typedefs to a
       common back end type (hwloc_bitmap_t), and therefore all the hwloc bitmap functions are
       applicable to both hwloc_cpuset_t and hwloc_nodeset_t (see The bitmap API).

       The rationale for having two different types is that even though the actions one wants to
       perform on these types are the same (e.g., enable and disable individual items in the
       set/mask), they're used in very different contexts: one for specifying which processors to
       use and one for specifying which NUMA nodes to use. Hence, the name difference is really
       just to reflect the intent of where the type is used.

Typedef Documentation

   typedef hwloc_const_bitmap_t hwloc_const_cpuset_t
       A non-modifiable hwloc_cpuset_t.

   typedef hwloc_const_bitmap_t hwloc_const_nodeset_t
       A non-modifiable hwloc_nodeset_t.

   typedef hwloc_bitmap_t hwloc_cpuset_t
       A CPU set is a bitmap whose bits are set according to CPU physical OS indexes. It may be
       consulted and modified with the bitmap API as any hwloc_bitmap_t (see hwloc/bitmap.h).

   typedef hwloc_bitmap_t hwloc_nodeset_t
       A node set is a bitmap whose bits are set according to NUMA memory node physical OS
       indexes. It may be consulted and modified with the bitmap API as any hwloc_bitmap_t (see
       hwloc/bitmap.h).

       When binding memory on a system without any NUMA node (when the whole memory is considered
       as a single memory bank), the nodeset may be either empty (no memory selected) or full
       (whole system memory selected).
