hwlocality_linux


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)
 

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 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.

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.

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 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.
