NAME
Linux-only helpers - Functions int hwloc_linux_parse_cpumap_file (FILE *file, hwloc_cpuset_t set) int hwloc_linux_set_tid_cpubind (hwloc_topology_t topology, pid_t tid, hwloc_const_cpuset_t set) int hwloc_linux_get_tid_cpubind (hwloc_topology_t topology, pid_t tid, hwloc_cpuset_t set) Detailed Description This includes helpers for manipulating linux kernel cpumap files, and hwloc equivalents of the Linux sched_setaffinity and sched_getaffinity system calls. Function Documentation int hwloc_linux_get_tid_cpubind (hwloc_topology_ttopology, pid_ttid, hwloc_cpuset_tset) Get the current binding of thread tid. The behavior is exactly the same as the Linux sched_getaffinity system call, but uses a hwloc cpuset. int hwloc_linux_parse_cpumap_file (FILE *file, hwloc_cpuset_tset) Convert a linux kernel cpumap file file into hwloc CPU set. Might be used when reading CPU set from sysfs attributes such as topology and caches for processors, or local_cpus for devices. int hwloc_linux_set_tid_cpubind (hwloc_topology_ttopology, pid_ttid, hwloc_const_cpuset_tset) Bind a thread tid on cpus given in cpuset set. The behavior is exactly the same as the Linux sched_setaffinity system call, but uses a hwloc cpuset. Author Generated automatically by Doxygen for Hardware Locality (hwloc) from the source code.

NAME
Helpers for manipulating Linux libnuma nodemask_t - Functions static inline int hwloc_cpuset_to_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_const_cpuset_t cpuset, nodemask_t *nodemask) static inline int hwloc_nodeset_to_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_const_nodeset_t nodeset, nodemask_t *nodemask) static inline int hwloc_cpuset_from_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_cpuset_t cpuset, const nodemask_t *nodemask) static inline int hwloc_nodeset_from_linux_libnuma_nodemask (hwloc_topology_t topology, hwloc_nodeset_t nodeset, const nodemask_t *nodemask) Detailed Description Note: The Linux libnuma nodemask_t interface is deprecated and its implementation is at least incorrect with respect to sparse NUMA node ids. It is strongly advised to use struct bitmask instead of nodemask_t, or even to use hwloc directly. Function Documentation static inline int hwloc_cpuset_from_linux_libnuma_nodemask (hwloc_topology_ttopology, hwloc_cpuset_tcpuset, const nodemask_t *nodemask) [static] Convert libnuma nodemask nodemask into hwloc CPU set cpuset. This function may be used before calling some old libnuma functions that use a nodemask_t as an output parameter. static inline int hwloc_cpuset_to_linux_libnuma_nodemask (hwloc_topology_ttopology, hwloc_const_cpuset_tcpuset, nodemask_t *nodemask) [static] Convert hwloc CPU set cpuset into libnuma nodemask nodemask. This function may be used before calling some old libnuma functions that use a nodemask_t as an input parameter. static inline int hwloc_nodeset_from_linux_libnuma_nodemask (hwloc_topology_ttopology, hwloc_nodeset_tnodeset, const nodemask_t *nodemask) [static] Convert libnuma nodemask nodemask into hwloc NUMA node set nodeset. This function may be used before calling some old libnuma functions that use a nodemask_t as an output parameter. static inline int hwloc_nodeset_to_linux_libnuma_nodemask (hwloc_topology_ttopology, hwloc_const_nodeset_tnodeset, nodemask_t *nodemask) [static] Convert hwloc NUMA node set nodeset into libnuma nodemask nodemask. This function may be used before calling some old libnuma functions that use a nodemask_t as an input parameter.
