Detailed Description

       This interface helps converting between Linux libnuma bitmasks and hwloc cpusets and nodesets.

       It also offers a consistent behavior on non-NUMA machines or non-NUMA-aware kernels by assuming that the
       machines have a single NUMA node.

       Note:
           Topology topology must match the current machine.

           The behavior of libnuma is undefined if the kernel is not NUMA-aware. (when CONFIG_NUMA is not set in
           the kernel configuration). This helper and libnuma may thus not be strictly compatible in this case,
           which may be detected by checking whether numa_available() returns -1.

Function Documentation

   static inline int hwloc_cpuset_from_linux_libnuma_bitmask (hwloc_topology_ttopology, hwloc_cpuset_tcpuset,
       const struct bitmask *bitmask) [static]
       Convert libnuma bitmask bitmask into hwloc CPU set cpuset. This function may be used after calling many
       numa_ functions that use a struct bitmask as an output parameter.

   static inline struct bitmask * hwloc_cpuset_to_linux_libnuma_bitmask (hwloc_topology_ttopology,
       hwloc_const_cpuset_tcpuset) [static]
       Convert hwloc CPU set cpuset into the returned libnuma bitmask. The returned bitmask should later be
       freed with numa_bitmask_free.

       This function may be used before calling many numa_ functions that use a struct bitmask as an input
       parameter.

       Returns:
           newly allocated struct bitmask.

   static inline int hwloc_nodeset_from_linux_libnuma_bitmask (hwloc_topology_ttopology, hwloc_nodeset_tnodeset,
       const struct bitmask *bitmask) [static]
       Convert libnuma bitmask bitmask into hwloc NUMA node set nodeset. This function may be used after calling
       many numa_ functions that use a struct bitmask as an output parameter.

   static inline struct bitmask * hwloc_nodeset_to_linux_libnuma_bitmask (hwloc_topology_ttopology,
       hwloc_const_nodeset_tnodeset) [static]
       Convert hwloc NUMA node set nodeset into the returned libnuma bitmask. The returned bitmask should later
       be freed with numa_bitmask_free.

       This function may be used before calling many numa_ functions that use a struct bitmask as an input
       parameter.

       Returns:
           newly allocated struct bitmask.
