HTL_thread_executor_set_affinity

Interface Definition

int HTL_thread_executor_set_affinity(HTL_thread_executor_t executor, int num_cpuids, int *cpuids);

Description

HTL_thread_executor_set_affinity() is used to update the CPUs bound to the executor.

• If num_cpuids is greater than 0, the new executor is bound to the corresponding CPU IDs.
• If num_cpuids is 0, the CPUs bound to the executor are reset.

Parameters

Return Value

• HTL_THREAD_SUCCESS: success.
• Other values: failure. For details, see the error code descriptions.

Example

    int *cpuids = (int *)malloc(sizeof(int) * 16);
    int i;
    for (i = 0; i < 16; i++)
        cpuids[i] = i;        
    HTL_thread_executor_t self_executor;
    ret = HTL_thread_executor_self(&self_executor);
    ret = HTL_thread_executor_set_affinity(self_executor, 16, cpuids);
