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
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.
|HWLOC_DECLSPEC int hwloc_linux_parse_cpumap_file
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.
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.
