hwlocality...ma_bitmask(3) Library Functions Manual hwlocality...ma_bitmask(3)

NAME
       hwlocality_linux_libnuma_bitmask	- Interoperability with	Linux libnuma
       bitmask

SYNOPSIS
   Functions
       static struct bitmask * hwloc_cpuset_to_linux_libnuma_bitmask
	   (hwloc_topology_t topology, hwloc_const_cpuset_t cpuset)
       static struct bitmask * hwloc_nodeset_to_linux_libnuma_bitmask
	   (hwloc_topology_t topology, hwloc_const_nodeset_t nodeset)
       static int hwloc_cpuset_from_linux_libnuma_bitmask (hwloc_topology_t
	   topology, hwloc_cpuset_t cpuset, const struct bitmask *bitmask)
       static int hwloc_nodeset_from_linux_libnuma_bitmask (hwloc_topology_t
	   topology, hwloc_nodeset_t nodeset, const struct bitmask *bitmask)

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

       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 int hwloc_cpuset_from_linux_libnuma_bitmask (hwloc_topology_t
       topology, hwloc_cpuset_t	cpuset,	const struct bitmask * bitmask)
       [inline],  [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.

       Returns
	   0 on	success.

	   -1 with errno set to	ENOMEM if some internal	reallocation failed.

   static struct bitmask * hwloc_cpuset_to_linux_libnuma_bitmask
       (hwloc_topology_t topology, hwloc_const_cpuset_t	cpuset)	[inline],
       [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, or NULL on error.

   static int hwloc_nodeset_from_linux_libnuma_bitmask (hwloc_topology_t
       topology, hwloc_nodeset_t nodeset, const	struct bitmask * bitmask)
       [inline],  [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.

       Returns
	   0 on	success.

	   -1 with errno set to	ENOMEM if some internal	reallocation failed.

   static struct bitmask * hwloc_nodeset_to_linux_libnuma_bitmask
       (hwloc_topology_t topology, hwloc_const_nodeset_t nodeset) [inline],
       [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, or NULL on error.
