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_getaffinity 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.
