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.

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_ttopology, hwloc_const_cpuset_tcpuset) [static], [read] 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_ttopology, hwloc_nodeset_tnodeset, const struct bitmask *bitmask) [static] Convert libnuma bitmask bitmask into hwloc NUMA node set nodeset.
