NAME

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_setaffinity 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.
