This includes helpers for manipulating Linux kernel cpumap files, and hwloc equivalents of the Linux sched_setaffinity and sched_getaffinity system calls.
Get the current binding of thread
set (previously allocated by the caller) is filled with the list of PUs which the thread was last bound to.
The behavior is exactly the same as the Linux sched_getaffinity system call, but uses a hwloc cpuset.
- This is equivalent to calling hwloc_get_proc_cpubind() with HWLOC_CPUBIND_THREAD as flags.
||const char *
Convert a linux kernel cpumask file
path into a hwloc bitmap
Might be used when reading CPU set from sysfs attributes such as topology and caches for processors, or local_cpus for devices.
- This function ignores the HWLOC_FSROOT environment variable.
Bind a thread
tid on cpus given in cpuset
The behavior is exactly the same as the Linux sched_setaffinity system call, but uses a hwloc cpuset.
- This is equivalent to calling hwloc_set_proc_cpubind() with HWLOC_CPUBIND_THREAD as flags.
