HWLOC_DECLSPEC int | hwloc_linux_parse_cpumap_file (FILE *file, hwloc_cpuset_t set) |
Convert a linux kernel cpumap file file into hwloc CPU set. | |
HWLOC_DECLSPEC int | hwloc_linux_set_tid_cpubind (hwloc_topology_t topology, pid_t tid, hwloc_const_cpuset_t set) |
Bind a thread tid on cpus given in cpuset set . | |
HWLOC_DECLSPEC int | hwloc_linux_get_tid_cpubind (hwloc_topology_t topology, pid_t tid, hwloc_cpuset_t set) |
Get the current binding of thread tid . |
This includes helpers for manipulating linux kernel cpumap files, and hwloc equivalents of the Linux sched_setaffinity and sched_getaffinity system calls.
HWLOC_DECLSPEC int hwloc_linux_get_tid_cpubind | ( | hwloc_topology_t | topology, | |
pid_t | tid, | |||
hwloc_cpuset_t | set | |||
) |
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.
HWLOC_DECLSPEC int hwloc_linux_parse_cpumap_file | ( | FILE * | file, | |
hwloc_cpuset_t | set | |||
) |
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.
HWLOC_DECLSPEC int hwloc_linux_set_tid_cpubind | ( | hwloc_topology_t | topology, | |
pid_t | tid, | |||
hwloc_const_cpuset_t | set | |||
) |
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.
