pthread_attr_setaffinity_np函数定义在pthread.h头文件中,其函数原型为: int pthread_attr_setaffinity_np(pthread_attr_t *attr, size_t cpusetsize, const cpu_set_t *cpuset); int pthread_attr_getaffinity_np(const pthread_attr_t *attr, size_t cpusetsize, cpu_set_t *cpuset); 这两个函数用于...
pthread_setname_np (pthread_t pthread, const char *name) int Sets the thread name. pthread_getaffinity_np (pthread_t td, size_t size, cpu_set_t *set) int Obtains the affinity of a thread. pthread_setaffinity_np (pthread_t td, size_t size, cpu_set_t *set) int Sets the...

Thepthread_setaffinity_np() function sets the CPU affinity mask of the threadthreadto the CPU set pointed to bycpuset. If the call is successful, and the thread is not currently running on one of the CPUs incpuset, then it is migrated to one of those CPUs. Thepthread_getaffinity_np()...
[E:onnxruntime:Default,ThreadMain] pthread_setaffinity_np failed for thread: 531, index: 6, mask: {7, 39, }, error code: 22 error msg: Invalidargument. Specify the number of threads explicitly so the affinity is not set. 这个错误的原因在于开源的onnx在分配cpu时只能从0开始,因此如果一个...
注意的地方:如果用CPU_SET这个宏来设置那么可以直接用0,1,2作为cpu的id。如果直接对mask赋值,需要注意是按照bit来的:30 unsigned long mask = 1; /* processor 0 */ 31 32 /* bind process to processor 0 */ 33 if (sched_setaffinity(0, sizeof(mask), &mask) <0) { 34 perror("sched_...
linux下将不同线程绑定到不同core和cpu上——pthread_setaffinity_np,注意的地方:如果用CPU_SET这个宏来设置那么可以直接用0,1,2作为cpu的id。如果直接对mask赋值,需要注意是按照bit来的:
