NAME¶
Linux-specific helpers -Functions¶
int hwloc_linux_parse_cpumap_file (FILE *file, 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. Note:This is equivalent to calling
hwloc_get_proc_cpubind() with HWLOC_CPUBIND_THREAD as flags.
int hwloc_linux_get_tid_last_cpu_location ( hwloc_topology_ttopology, pid_ttid, hwloc_bitmap_tset)¶
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.
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. Note:This is equivalent to calling
hwloc_set_proc_cpubind() with HWLOC_CPUBIND_THREAD as flags.
