Detailed Description

Function Documentation

static inline int hwloc_cpuset_from_linux_libnuma_bitmask ( hwloc_topology_t  topology,
hwloc_cpuset_t  cpuset,
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_t  topology,
hwloc_const_cpuset_t  cpuset 
)
staticread

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_t  topology,
hwloc_nodeset_t  nodeset,
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_t  topology,
hwloc_const_nodeset_t  nodeset 
)
staticread

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.
