NAME

       hwlocality_linux - Linux-specific 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)
       int hwloc_linux_get_tid_last_cpu_location (hwloc_topology_t topology, pid_t tid,
           hwloc_bitmap_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_t topology, pid_t tid, hwloc_cpuset_t set)
       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.

       Note:
           This is equivalent to calling hwloc_get_proc_cpubind() with HWLOC_CPUBIND_THREAD as
           flags.

   int hwloc_linux_get_tid_last_cpu_location (hwloc_topology_t topology, pid_t tid,
       hwloc_bitmap_t set)
       Get the last physical CPU where thread tid ran.

       Note:
           This is equivalent to calling hwloc_get_proc_last_cpu_location() with
           HWLOC_CPUBIND_THREAD as flags.

   int hwloc_linux_parse_cpumap_file (FILE * file, hwloc_cpuset_t set)
       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_t topology, pid_t tid, hwloc_const_cpuset_t
       set)
       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.

       Note:
           This is equivalent to calling hwloc_set_proc_cpubind() with HWLOC_CPUBIND_THREAD as
           flags.
