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