NAME

Helpers for manipulating Linux libnuma unsigned long masks -  

Functions


static __hwloc_inline int hwloc_cpuset_to_linux_libnuma_ulongs (hwloc_topology_t topology, hwloc_const_cpuset_t cpuset, unsigned long *mask, unsigned long *maxnode)
Convert hwloc CPU set cpuset into the array of unsigned long mask.
static __hwloc_inline int hwloc_cpuset_from_linux_libnuma_ulongs (hwloc_topology_t topology, hwloc_cpuset_t cpuset, const unsigned long *mask, unsigned long maxnode)
Convert the array of unsigned long mask into hwloc CPU set.  

Function Documentation

 

static __hwloc_inline int hwloc_cpuset_from_linux_libnuma_ulongs (hwloc_topology_t topology, hwloc_cpuset_t cpuset, const unsigned long * mask, unsigned long maxnode) [static]

Convert the array of unsigned long mask into hwloc CPU set. mask is a array of unsigned long that will be read. maxnode contains the maximal node number that may be read in mask.

This function may be used after calling get_mempolicy or any other function that takes an array of unsigned long as output parameter (and possibly a maximal node number as input parameter).  

static __hwloc_inline int hwloc_cpuset_to_linux_libnuma_ulongs (hwloc_topology_t topology, hwloc_const_cpuset_t cpuset, unsigned long * mask, unsigned long * maxnode) [static]

Convert hwloc CPU set cpuset into the array of unsigned long mask. mask is the array of unsigned long that will be filled. maxnode contains the maximal node number that may be stored in mask. maxnode will be set to the maximal node number that was found, plus one.

This function may be used before calling set_mempolicy, mbind, migrate_pages or any other function that takes an array of unsigned long and a maximal node number as input parameter.
